- LLVM for prebuilt packages bumped to v18.1.8 (incl. macOS arm64). (#4712)
- Android: NDK for prebuilt package bumped from r26d to r27. (#4711)
- ldc2.conf: %%ldcconfigpath%% placeholder added - specifies the directory where current configuration file is located. (#4717)

- Supports LLVM 15 - 18. Support for LLVM 11 - 14 was dropped. The CLI options
-passmanagerand-opaque-pointerswere removed.

- Support for LLVM 18. The prebuilt packages use v18.1.5 (except for macOS arm64). (#4599, #4605, #4607, #4604, #4628, #4642)
- Android: Switch to native ELF TLS, supported since API level 29 (Android v10), dropping our former custom TLS emulation (requiring a modified LLVM and a legacy ld.bfd linker). The prebuilt packages themselves require Android v10+ (armv7a) / v11+ (aarch64) too, and are built with NDK r26d. Shared druntime and Phobos libraries are now available (
-link-defaultlib-shared), as on regular Linux. (#4618)- Please don't use the official macOS arm64 package (incl. the universal package on arm64) to cross-compile to Android. That package still uses our previous LLVM v17.0.6, which still includes the custom TLS emulation, but druntime expects native TLS now on Android. Resort to the x86_64 package in that case.

- Support for LLVM 16. The prebuilt packages use v16.0.6. (#4411, #4423)
- We have come across miscompiles with LLVM 16's newly-enabled-by-default function specializations (on Win64 and macOS). To be on the safe side, LDC disables them by default for all targets via
-func-specialization-size-threshold=1000000000inetc/ldc2.conf(and separately for LTO on Posix platforms). To enable the function specializations, explicitly override it with e.g.-func-specialization-size-threshold=100(the LLVM 16 default) and, for LTO on Posix, a similar LTO plugin option in the linker cmdline (see linker cmdline with-v).

- Frontend, druntime and Phobos are at version 2.103.1, incl. new command-line option
-verror-supplements. (#4345) - The
--plugincommandline option now also accepts semantic analysis plugins. Semantic analysis plugins are recognized by exporting the symbol:extern(C) void runSemanticAnalysis(Module m). The plugin'srunSemanticAnalysisfunction is called for each module, after all other semantic analysis steps (also after DCompute SemA), just before object codegen. (#4430) - New tool
ldc-build-pluginthat helps compiling user plugins. It downloads the correct LDC source version (if it's not already available), and calls LDC with the correct commandline flags to build a plugin. (#4430) - New commandline option
-femit-local-var-lifetimethat enables variable lifetime (scope) annotation to LLVM IR codegen. Lifetime annotation enables stack memory reuse for local variables with non-overlapping scope. (#4395) - C files are now automatically preprocessed using the external C compiler (configurable via
-gccor theCCenvironment variable, and-Xccfor extra flags). Extra preprocessor flags (e.g., include dirs and manual defines) can be added via new command-line option-P. (#4417)- Windows: If
clang-cl.exeis onPATH, it is preferred over Microsoft'scl.exeby default (e.g., to avoid printing the C source file name to stderr during preprocessing).
- Windows: If
- Less pedantic checks for conflicting C(++) function declarations when compiling multiple modules to a single object file ('Error: Function type does not match previously declared function with the same mangled name'). The error now only appears if an object file actually references multiple conflicting functions. (#4420)
- New command-line option
--fcf-protection, which enables Intel's Control-Flow Enforcement Technology (CET). (#4437)
- Supports LLVM 9.0 - 15.0.
- Handle potential lambda mangle collisions across separately compiled object files (and the linker then silently picking an arbitrary implementation). Lambdas (and their nested global variables) are now internal to each referencing object file (
staticlinkage in C). (#4415)
- New command-line option
--fwarn-stack-size=<threshold>with LLVM 13+. (#4378) - New command-line option

- Linker-level dead code elimination is enabled by default for Apple, wasm and all ELF targets too now. (#4320)
- Vector comparisons (==, !=, <, <=, >, >=) now yield a vector mask. Identity comparisons (
is,!is) still yield a scalarbool. (3a59ee81) - New
timetrace2txttool for easier inspection of--ftime-traceoutput. (#4335) --ftime-tracenow also traces CTFE execution: the start expression of CTFE and function calls during CTFE. (#4339)
- Supports LLVM 9.0 - 15.0.

- Fix compiler crash. (#4130, #4135)
- The former druntime and dmd-testsuite git submodules are now part of the LDC repo directly, leaving Phobos as single remaining submodule. We are now using a subset of the DMD repo (which includes druntime since v2.101), rewritten via
git filter-repoand exposed asdmd-rewrite-*branches/tags in the LDC repo, to merge newer frontend+druntime+tests from upstream DMD. Thetests/d2/dmd-testsuitedir was moved totests/dmd. (#4274, #4276)
- Frontend, druntime and Phobos are at version 2.100.1. (#3970, #4008, #4009)
- LLVM for prebuilt packages bumped to v14.0.3. (#3952, #3979)
- All LLVM targets are enabled now (=> more targets for cross-compilation).
- For the Mac package, the minimum supported macOS version has been raised to v10.12.
- The minimum D version for bootstrapping has been raised to v2.079 (for GDC: v9.4), in line with DMD. (#3956)
- The minimum LLVM version has been raised to v9.0. (#3960)
- New LeakSanitizer support via
-fsanitize=leak(not (yet?) supported on Windows). (#4005) - New prebuilt universal macOS package, runnable on both x86_64 and arm64, and enabling x86_64/arm64 macOS/iOS cross-compilation targets out of the box (
-mtriple={x86_64,arm64}-apple-{macos,ios12.0}). The x86_64 package doesn't bundle any arm64 libs anymore; the arm64 package newly bundles iOS libs (arm64). (#3958)- Avoid an external x86_64-only dub, use the bundled universal dub executable instead.
- Supports LLVM 9.0 - 14.0.
- Enable output of variable names in ASan and MSan error reporting. (#4004)
- Report unexpected type repaints as fatal ICEs instead of crashing. (#3990, #3991)
- Main CI was moved from Azure Pipelines to GitHub Actions. Any fork on GitHub can trivially reuse the fully automated prebuilt packages generation & upload to a GitHub release. (#3978)
- Frontend, druntime and Phobos are at version 2.099.1. (#3917, #3893, #3937, #3953)
- Support for LLVM 13 and 14. The prebuilt packages use v13.0.1. (#3842, #3951)
- On Linux, LDC doesn't default to the
ld.goldlinker anymore. The combination of LLVM 13+ and older gold linkers can apparently cause problems. We recommend using LLD, e.g., via-linker=lldor by setting your default/usr/bin/ldsymlink; it's significantly faster too. -linkonce-templatesis less aggressive by default now and IMHO production-ready. (#3924)- When linking manually (not via LDC) against shared druntime, it is now required to link the bundled
lib/ldc_rt.dso.o[bj]object file into each binary. It replaces the previously Windows-specificdso_windows.obj. (#3850) - Breaking
extern(D)ABI change for all targets: formal parameters of non-variadic functions aren't reversed anymore, in line with the spec. For 32-bit x86, the first parameter is accordingly now potentially passed in EAX, not the last one. So non-variadicextern(D)functions with multiple explicit parameters will break if expecting parameters in specific registers or stack slots, e.g., naked DMD-style inline assembly.

- Frontend, druntime and Phobos are at version 2.097.1+. (#3741, #3770, #3771, #3790, #3794, #3796, #3799) (new)
- LLVM for prebuilt packages bumped to v12.0.1, and Linux base image to Ubuntu 18.04. Unfortunately, the dynamic-compile (JIT) functionality is lost this way - it needs some more work to adapt to a newer LLVM API. (#3701, #3789)
- Prebuilt packages now bundle reggae, a meta build tool to generate ninja/make build files for dub projects (and more). Building large projects with many dependencies can be significantly sped-up via parallelization and dependency tracking for incremental builds. (#3739)
Basic usage, in a dub project dir (containing a
dub.{sdl,json}file):reggae -b ninja|make --dc=ldc2 # only needed the first time or when adding source files ninja|make [-j<N>] - Greatly improved DLL support on Windows, making it almost as easy as on Posix:
-fvisibility=publicnow also affects Windows, exporting all defined symbols as on Posix, without explicitexportvisibility. Compiling a DLL with-sharednow defaults to-fvisibility=publicfor consistency with Posix. (#3703)- This paved the way for druntime and Phobos DLLs, now bundled with prebuilt Windows packages and linkable via
-link-defaultlib-shared(default with-shared, consistent with Posix targets). Previous hacks to partially accomodate for multiple, statically linked druntimes and Phobos in a single process (GC proxy etc.) aren't required any longer. With-link-defaultlib-shared, LDC now defaults to-mscrtlib=msvcrt, linking against the shared MSVC runtime. (ldc-developers/druntime#197, #3704, ldc-developers/druntime#198) - Limitation: TLS variables cannot be accessed directly across DLL boundaries. This can be worked around with an accessor function, e.g., ldc-developers/druntime@5d3e21a35d.
- Non-TLS
extern(D)global variables not defined in a root module aredllimported (with-fvisibility=public, or - restricted to druntime/Phobos symbols - with-link-defaultlib-shared). Compiling all modules of a DLL at once thus avoids linker warnings about 'importing locally defined symbol'. When linking a DLL against a static library, the static library may likely need to be compiled with-fvisibility=publicto make its globals importable from the DLL. There's a new-dllimportoption for explicit control. (#3763) - Caveat: symbols aren't uniqued across the whole process, so can be defined in multiple DLLs/executables, each with their own address, so you cannot rely on TypeInfos, instantiated symbols and functions to have the same address for the whole process.
- When linking manually (not via LDC), binaries linked against druntime DLL need to include new
lib\dso_windows.obj. - To restore the previous behavior of
-shared, add-fvisibility=hidden -link-defaultlib-shared=false.
- Windows: ANSI color codes can now be enforced for redirected stderr via
-enable-color. (#3744) - Prebuilt Linux and Mac packages now use the mimalloc allocator, significantly increasing compiler performance in some cases. (#3758, #3759)
- The prebuilt macOS x64 package now bundles shared druntime/Phobos libs for iOS too. (#3764)
- Possibly more performant shared Phobos library by compiling to a single object file with implicit cross-module inlining. (#3757)
- New
-cov-incrementoption for more performant coverage count execution. (#3724) -fsanitize=memory: Bundle according LLVM compiler-rt library and add new-fsanitize-memory-track-originsoption. (#3751)- New LDC-specific language addition:

extern(D): Pass/return Homogeneous Vector Aggregates in SIMD registers. (#3610)
-linkonce-templatescomes with a new experimental template emission scheme and is now suited for projects consisting of multiple object files too. It's similar to C++, emitting templated symbols into each referencing compilation unit with optimizer-discardablelinkonce_odrlinkage. The consequences are manifold - each object file is self-sufficient wrt. templated symbols, naturally working around any template-culling bugs and also meaning increased opportunity for inlining and less need for LTO. The probably biggest advantage is that the optimizer can discard unusedlinkonce_odrsymbols early instead of optimizing and forwarding to the assembler. So this is especially useful to decrease compilation times with-Oand can at least in some scenarios greatly outweigh the (potentially very much) higher number of symbols defined by the glue layer - on my box, building optimized dub (all-at-once) is 28% faster with-linkonce-templates, and building the optimized Phobos unittests (per module) 56% faster. Libraries compiled with-linkonce-templatescan generally not be linked against dependent code compiled without-linkonce-templates; the other way around works. (#3600)- Emit function/delegate literals as
linkonce_odr, as they are emitted into each referencing compilation unit too. (#3650) - Exploit ABI specifics with

- Traverse full chain of nested aggregates when resolving a nested variable. (#3556, #3558)
- CI: Linux AArch64 is now also tested by a Travis job, because Shippable has sadly become unreliable. (#3469)
- Building LDC with an LDC host compiler might be somewhat faster now (requires
-DLDC_LINK_MANUALLY=OFFin the CMake command-line on non-Windows hosts). (#3575)
- Frontend, druntime and Phobos are at version 2.093.1+, incl. new command-line option
-vtemplates. (#3476, #3538, #3541) - Min required LLVM version raised to v6.0, dropping support for v3.9-5.0. (#3493)
- LLVM for prebuilt packages bumped to v10.0.1. (#3513)
- The prebuilt Mac package now also includes prebuilt druntime/Phobos for the iOS/x86_64 simulator, making cross-compilation work out of the box with
-mtriple=x86_64-apple-ios12.0. (#3478) - Windows: New
-gdwarfCLI option to emit DWARF debuginfos for MSVC targets, e.g., for debugging with gdb/lldb. (#3533) - New
-platformlibCLI option to override the default linked-with platform libraries, e.g., when targeting bare-metal. (#3374, #3475)
- Supports LLVM 6.0 - 10.0.
- Fix regression since v1.22: shared druntime potentially overriding libstdc++ symbols and breaking exceptions in C++ libraries. (#3530, #3537)
- Fix naked DMD-style asm emission for non-Mac x86 Darwin targets (e.g., iOS simulators). (#3478)
-betterC: Don't use unsupported EH for handling clean-ups. (#3479, #3482)- dcompute: Fix wrong address space loads and stores. Thx Rob! (#3428)
- Fix ICE wrt. missing IR declarations for some forward-declared functions. (#3496, #3503)
- Fix ICE wrt. inline IR and empty parameter types tuple. (#3509)
- Fix PGO issues. (#3375, #3511, #3512, #3524)
- Improve support for LLVM's ThreadSanitizer. (#3522)
- Fix linker cmdline length limitation via response files. (#3535, #3536)
- Compiler performance wrt. string literals emission has been improved. Thx @looked-at-me! (#3490, #3492)
- Link libstdc++ statically for
libldc-jit.soof prebuilt Linux packages, to increase portability. (#3473, #3474) - Set up Visual D when using the Visual Studio CMake generator, making LDC compiler development on Windows a smooth out-of-the-box experience. (#3494)
- Frontend, druntime and Phobos are at version 2.092.1+. (#3413, #3416, #3429, #3434, #3452, #3467)
- AArch64: All known ABI issues have been fixed. C(++) interop should now be on par with x86_64, and variadics usable with
core.{vararg,stdc.stdarg}. (#3421) - Windows hosts: DMD's Visual C++ toolchain detection has been adopted. As that's orders of magnitude faster than the previous method involving the MS batch file, auto-detection has been enabled by default, so if you have a non-ancient Visual C++ installation, it will now be used automatically for linking. The environment setup has been reduced to the bare minimum (
LIBandPATH). (#3415) - FreeBSD x64: CI with CirrusCI is now fully green and includes automated prebuilt package generation. The package depends on the
llvmports package and should currently work on FreeBSD 11-13. (#3453, #3464) - Link-time overridable
@weakfunctions are now emulated for Windows targets and work properly for ELF platforms. For ELF, LDC doesn't emit any COMDATs anymore. (#3424) - New
ldc.gccbuiltins_{amdgcn,nvvm}for AMD GCN and NVIDIA PTX targets. (#3411) - druntime: Significant speed-up for
core.math.ldexp. (#3440, #3446)
- Supports LLVM 3.9 - 10.0.
- Cross-module inlining (incl.
pragma(inline, true)): Enable emission into multiple object files. This may have a significant impact on performance (incl. druntime/Phobos) when not using LTO. (#3126, #3442) - Android: Fix TLS initialization regression (introduced in v1.21) and potential alignment issues. Unfortunately, the
ld.bfdlinker is required for our custom TLS emulation scheme, unless you're willing to use a custom linker script. So-linker=bfdis the new default for Android targets. (#3462) - Casting (static and dynamic) arrays to vectors now loads the data instead of splatting the first element. (#3418, #3419)
- Fix return statements potentially accessing memory from destructed temporaries. (#3426)
- Add proper support for
-checkaction=halt. (#3430, #3431) - druntime: Include
core.stdcpp.*modules. (#3103, #3158) - GCC-style asm: Add support for indirect input operands (
"m"). (#3438) - FreeBSD: Fix backtraces for optimized code by switching to external
libexecinfo. (#3108, #3453) - FreeBSD: Fix C math related issues (incl. CTFE math issues) by bringing
core.stdc.{math,tgmath}up to speed. (dlang/druntime#3119) - Fix ICE for captured parameters not passed on the LLVM level. (#3441)
- Convenience fixes for RISC-V and other exotic targets. (#3457, #3460)
- When printing compile-time reals to hex strings (mangling, .di headers), LDC now uses LLVM instead of the host C runtime, for proper and consistent results. (#3410)
- One limitation for exotic hosts wrt. C
long doubleprecision has been lifted. (#3414) - For AVR targets, the compiler now predefines
AVRand emits all TLS globals as regular__gsharedones. (#3420) - WebAssembly: New memory grow/size intrinsics. (ldc-developers/druntime#187)
- New
-fno-pltoption to avoid PLT external calls. (#3443) - iOS/arm64 CI, running the debug druntime & Phobos unittests on an iPhone 6S. Thx Jacob for this tedious work! (#3379, #3450)
- Frontend, druntime and Phobos are at version 2.091.1+, incl. new CLI switches
-verror-styleand-HC,-HCd,-HCf. (#3333, #3399) - iOS (incl. watchOS and tvOS) support has landed in druntime and Phobos (thanks Jacob!). All unittests are green on iOS/arm64. The prebuilt macOS package includes prebuilt druntime & Phobos libraries for iOS/arm64, for first
-mtriple=arm64-apple-ios12.0cross-compilation experiments. (#3373) - LLVM for prebuilt packages upgraded to v10.0.0. Android NDK version bumped to r21. (#3307, #3387, #3398)
- Initial support for GCC/GDC-style inline assembly syntax, besides DMD-style inline asm and LDC-specific
__asm, enabling to write inline asm that is portable across GDC/LDC and corresponds to the GCC syntax in C. See ldc-developers/druntime#171 for examples wrt. how to transition from__asmto similar GCC-style asm. (#3304) - Inline assembly diagnostics have been extended by the D source location. (#3339)
- Android:
- Revamped druntime initialization, fixing related issues for i686/x86_64 targets, enabling the usage of the
ld.goldlinker (bfd isn't required anymore) as well as getting rid of the Dmain()requirement. (#3350, #3357, ldc-developers/druntime#178) - Reduced size for shared libraries by compiling druntime and Phobos with hidden visibility. (#3377)
- Revamped druntime initialization, fixing related issues for i686/x86_64 targets, enabling the usage of the
- Supports LLVM 3.9 - 10.0.
- Fixed tail calls in thunks, affecting AArch64 (the debug libraries now work) and possibly other architectures. (#3329, #3332)
- Windows: Do not emit any column infos for CodeView by default (like clang) & add
-gcolumn-info. (#3102, #3388) - Windows: Do not leak MSVC-environment-setup into
-runchild processes. A newLDC_VSDIR_FORCEenvironment variable can be used to enforce MSVC toolchain setup. (#3340, #3341) - Windows: Fix memory leak when throwing exceptions in threads. (#3369, ldc-developers/druntime#181)
- Try to use
memcmpfor (in)equality of non-mutable static arrays and mutable slices. (#3400, #3401) ldc.gccbuiltins_*: Lift 256-bit vector limit, adding 174 AVX512 builtins for x86; 512-bit vector aliases have been added tocore.simd. (#3405, #3406)
core.bitop.{bts,btr,btc}are now CTFE-able. (ldc-developers/druntime#182)- Do not fallback to host for critical section size of unknown targets. (#3389)
- Linux: Possibility to avoid passing
-fuse-ldtoccvia-linker=. (#3382) - WebAssembly: Switch from legacy linked-list ModuleInfo registry to
__minfosection. (#3348) - Windows: Bundled libcurl upgraded to v7.69.1, incl. the option to link it statically. (#3378)
- Windows: Switch to wide
wmainC entry point in druntime. (#3351) - druntime unittests are now compiled with
-checkaction=context.
- When building LDC, old LDC 0.17.*/ltsmaster host compilers miscompile LDC ≥ 1.21, leading to potential segfaults of the built LDC. Ltsmaster can still be used to bootstrap a first compiler and then let that compiler compile itself. (#3354)
- Non-Windows: Revert to strong
ModuleInfo.importedModulesreferences for correct module constructors execution order. (#3346, #3347)
- Frontend, druntime and Phobos are at version 2.090.1+. (#3262, #3296, #3306, #3317, #3326)
- Codegen preparations for:
- iOS/tvOS/watchOS on AArch64. Thanks Jacob! (#3288)
- WASI (WebAssembly System Interface) (#3295)
- The config file for multilib builds has been restructured by adding a separate section for the multilib target. This avoids
--no-warn-search-mismatchfor the linker and enables support for LLD. (#3276) - Support for embedding
pragma({lib,linkerDirective}, ...)in Mach-O object files. (#3259) E.g.,pragma(linkerDirective, "-framework", "CoreFoundation");makes Apple's linker pull in that framework when pulling in the compiled object file. ELF object files newly embedpragma(lib, ...)library names in a special.deplibssection, but that only works with LLD 9+ for now. - The
ldc-build-runtimetool has been slightly revised;--dFlagsnow extends the base D flags instead of overriding them. (1200601d44280d5f948a577b444ffa2dd4f9e433) ModuleInfo.importedModulesare now emitted as weak references (except on Windows, for LLD compatibility), following DMD. (#3262)- Windows: Bundled MinGW-based libs now support wide
wmainandwWinMainC entry points. (#3311)
- Supports LLVM 3.9 - 10.0.
- Potential stack overflows on Linux in GC worker threads. (#3127, dlang/druntime#2904)

--mtripleand not ignoring--confand--lowmemany longer. (#3268, #3275) - Support for data directives in DMD-style inline asm. (#3299, #3301)
- Cherry-picked fixes for soft-float targets. (#3292, dlang/phobos#7362, dlang/phobos#7366, dlang/phobos#7377)
- ICE during debuginfo generation for function literals inside enum declarations. (#3272, #3274)
- Misc. tweaks for
dmd-testsuite: (#3287, #3306)- Significantly accelerated by skipping uninteresting permutations.
- Switch from Makefile to
run.d, incl. moving LDC-specific exceptions from Makefile to individual test files and support for extendedDISABLEDdirectives.
- Addition of (recommendable!) Cirrus CI service (incl. FreeBSD) and removal of Semaphore CI. (#3298)
- Some improvements for
gdmdhost compilers, incl. CI tests. (#3286)
- Frontend, druntime and Phobos are at version 2.089.1+. (#3192, #3210, #3215, #3232, #3242, #3255, #3261)
- LLVM for prebuilt packages upgraded to v9.0.1; our fork has moved to ldc-developers/llvm-project. The x86[_64] packages newly include the experimental AVR backend. (#3244)
- Android: A prebuilt AArch64 package has been added. It also includes prebuilt druntime/Phobos libraries for x86_64; the armv7a package includes the i686 libraries. So all 4 Android targets are covered with prebuilt druntime/Phobos. (#3244)
- Breaking
extern(D)ABI change for Posix x86[_64]: non-POD arguments are now passed by ref under the hood, just like they already were forextern(C++). Some superfluous implicit blits have been optimized away as well, for all targets. (#3204) - Posix: Defaults to
ccnow for linking, notgcc(orclangfor FreeBSD 10+) - if theCCenvironment variable isn't set. Override with-gcc=<gcc|clang>. (#3202) - Codegen elision of dead branches for
ifstatements with constant condition (not depending on enabled LLVM optimizations). (#3134) - druntime: New
llvm_sideeffectintrinsic, new@coldfunction UDA and extended CAS functionality incore.atomic(incl. support for weak CAS and separate failure ordering). (ldc-developers/druntime#166, ldc-developers/druntime#167, #3220) - Windows: Bundled MinGW-based libs have been upgraded to use the .def files from MinGW-w64 v7.0.0. They now also contain a default
DllMainentry point as well as_[v]snprintf. (libs, #3142)
- Supports LLVM 3.9 - 9.0.
- Misc. CMake issues with some LLVM 9 configurations. (#3079, #3198)
- Equality/identity comparisons of vectors with length ≥ 32. (#3208, #3209)
ldc.gccbuiltins_*druntime modules now available to non-installed compiler too. (#3194, #3201)- Potential ICE when applying
@assumeUsedon global union. (#3221, #3222) Context from outer function, but no outer function?regression introduced in v1.11 (inability to access outer context fromextern(C++)methods). (#3234, #3235)- Lvalue expressions with nested temporaries to be destructed yielding a wrong lvalue. (#3233)
- druntime: Cherry-picked fix wrt. GC potentially collecting objects still referenced in other threads' TLS area. (dlang/druntime#2558)
- Frontend, druntime and Phobos are at version 2.088.1. (#3143, #3161, #3176, #3190)

- Preliminary Android CI, incl. experimental prebuilt armv7a package generation (API level 21, i.e., Android 5+). (#3164)
- Bundled dub upgraded to v1.17.0+ with improved LDC support, incl. cross-compilation (e.g.,
--arch=x86_64-pc-windows-msvc). (dlang/dub#1755, Wiki) - Init symbols of zero-initialized structs are no longer emitted. (#3131)
- druntime: DMD-compatible
{load,store}Unalignedandprefetchadded tocore.simd. (ldc-developers/druntime#163) - JIT improvements, incl. multi-threaded compilation. (#2758, #3154, #3174)
- Supports LLVM 3.9 - 9.0.
- Don't error out when initializing a
voidvector. (#3130, #3139) - druntime: Fix exception chaining for latest MSVC runtime v14.23, shipping with Visual Studio 2019 v16.3. (ldc-developers/druntime#164)

- Frontend, druntime and Phobos are at version 2.087.1+. (#3093, #3124)
- The upstream fix wrt. local templates can now receive local symbols hasn't been ported yet. (#3125)
- LLVM for prebuilt packages upgraded to v8.0.1. (#3113)
- Breaking change: Init symbols, TypeInfos and vtables of non-
exported aggregates are now hidden with-fvisibility=hidden. (#3129) - LLVM 8+: New intrinsics
llvm_*_sat(saturation arithmetic) andllvm_{min,max}imum. Thanks Stefanos! (ldc-developers/druntime#161, ldc-developers/druntime#162)
- Supports LLVM 3.9 - 8.0.
- Fix for v1.16.0 regression when returning
voidexpressions. (#3094, #3095) -lowmem(and on Windows,--DRT-*options) in response files (e.g., used by dub) aren't ignored anymore. (#3086)- Windows: LDC and LDMD now internally use UTF-8 strings only, incl. command-line options and environment variables. The LDC install dir, source file names etc. can now contain non-ASCII chars. For proper console output, especially to stderr, you'll need Windows 10 v1809+ and may need to set a Unicode console font (e.g., Consolas). (#611, #3086)
- Android: Linker errors when building LDC/LDMD should be fixed. (#3128)
- Support for recent
gdmdas D host compiler. Thanks Moritz! (#3087) - Do not require gold plugin when linking with LLD. (#3105)
- Enable linker stripping on FreeBSD (with non-
bfdlinkers). (#3106) - Some JIT bind fixes. (#3099, #3100)
- If you encounter segfaults in GC worker threads with shared druntime on Linux that are fixed by disabling new parallel GC marking (e.g., via
--DRT-gcopt=parallel:0in executable cmdline), please let us know about it: #3127
- Frontend, druntime and Phobos are at version 2.086.1, incl. a DIP1008 fix. (#3062, #3076, #3091)
- Non-Windows x86: Faster
realversions ofstd.math.{tan,expi}. (#2855) - dcompute: New
__traits(getTargetInfo, "dcomputeTargets"). (#3090)
- Supports LLVM 3.9 - 8.0 (incl. 7.1).
- Make
pragma(LDC_no_typeinfo)actually elide TypeInfo emission for structs, classes and interfaces. (#3068) - Windows: Fix DLL entry point in MinGW-based libs. (https://github.com/ldc-developers/mingw-w64-libs/commit/8d930c129daa798379b3d563617847f8e895f43e)

- Improved error message on global variable collision. (#3080, #3081)
- Frontend, druntime and Phobos are at version 2.085.1, incl. new command-line options
-preview,-revert,-checkaction=context,-verrors-contextand-extern-std. (#3003, #3039, #3053)- The Objective-C improvements from DMD 2.085 are not implemented. (#3007)
- Support for LLVM 8.0. The prebuilt packages have been upgraded to LLVM 8.0.0 and include the Khronos SPIRV-LLVM-Translator, so that dcompute can now emit OpenCL too. (#3005)
- Compiler memory requirements can now be reduced via the new
-lowmemswitch, which enables the garbage collector for the front-end and sacrifices compile times for less required memory. In some cases, the overall max process memory can be reduced by more than 60%; see ldc-developers#2916 (comment) for some numbers. (#2916)- Note for package maintainers: this feature requires a recent D host compiler (most notably, it doesn't work with ltsmaster), ideally LDC 1.15 itself due to important GC memory overhead improvements in 2.085 druntime.
- Support for generic
@llvmAttr("name")parameter UDAs, incl. new@restrictwith C-like semantics. (#3043) - macOS: 32-bit support was dropped in the sense of not being CI-tested anymore and the prebuilt macOS package now containing x86_64 libraries only.
MACOSX_DEPLOYMENT_TARGETfor the prebuilt package has been raised from 10.8 to 10.9. - Prebuilt packages don't depend on libtinfo and libedit anymore. (#1827, #3019)
- x86: SSSE3 isn't required for the prebuilt packages and generated optimized binaries anymore. (#3045)
- Supports LLVM 3.9 - 8.0.
- Implicit cross-module-inlining of functions annotated with
pragma(inline, true)without explicit-enable-cross-module-inlininghas been restored. (#2552, #3014) - Propagate well-known length of newly allocated dynamic arrays for better optimizability. (#3041, #3042)
- JIT: Support implicit
__chkstkcalls for Windows targets, e.g., for large stack allocations. (#3051)
- Addition of Azure Pipelines as CI service. It is the new main CI service and responsible for creating all prebuilt x86(_64) packages. AppVeyor has been dropped completely and CircleCI rededicated. (#2998)
- Frontend, druntime and Phobos are at version 2.084.1, incl. new command-line options
-mixin,-{enable,disable}-switch-errorsand-checkaction. (#2946, #2977, #2999)- Options
-release,-d-debugand-unittestdon't override preceding, more specific options (-{enable,disable}-{asserts,invariants,preconditions,postconditions,contracts}) anymore.
- Options
- Linking WebAssembly doesn't require
-link-internally(integrated LLD) anymore; an external linker (default:wasm-ld, override with-linker) can be used as well. (#2951) - Prebuilt Windows packages include LTO-able 32-bit druntime/Phobos too (previously: Win64 only).
- AddressSanitizer support for fibers (requires rebuilding the runtime libraries with CMake option
RT_SUPPORT_SANITIZERS=ON). (#2975, ldc-developers/druntime#152) - Support
pragma(LDC_extern_weak)for function declarations - if the function isn't available when linking, its address is null. (#2984)
- Supports LLVM 3.9 - 7.0.
- Fix C++ mangling regression for functions with multiple
realparameters introduced with v1.13, preventing to build DMD. (#2954, dlang/dmd#9129) - Fix context of some nested aggregates. (#2960, #2969)
- Support templated LLVM intrinsics with vector arguments. (#2962, #2971)

- AArch64: Fix DMD-style profile measurements. (#2950)
- Be less picky about placement of pragmas (allow intermediate
extern(C)etc.). (#2599) - MSVC: Fix
realC++ mangling to match Visual C++long double. (#2974) - Fix bad ICE noticed when building protobuf-d. (#2990, #2992)
- Fix ICE when directly indexing vector return value. (#2988, #2991)
- Fix identity comparisons of complex numbers. (#2918, #2993)
- MIPS32 fix for
core.stdc.stdarg. (#2989, ldc-developers/druntime#153) - Fix
core.atomic.cas()for 64-bit floating-point values. (#3000, #3001)
- Buggy older
ld.bfdlinker versions may wrongly strip out required symbols, e.g., ModuleInfos (so that e.g. no module ctors/dtors are run). LDC defaults told.goldon Linux.
- Frontend, druntime and Phobos are at version 2.083.1. (#2878, #2893, #2920, #2933)
- The Windows packages are now fully self-sufficient, i.e., a Visual Studio/C++ Build Tools installation isn't required anymore, as we now ship with MinGW-w64-based libraries, similar to DMD. Check out the included README.txt for all relevant details. (dlang/installer#346, ldc-developers#2886, Wiki: Cross-compiling with LDC)
- Debug info improvements:
- For GDB: printing global and imported symbols, non-member and member function calls. (#2826)
- For Visual Studio and mago: names, by-value params, nested variables. (#2895, #2908, #2909, #2912)
- Associative arrays now showing up properly (at least with mago), not as opaque
void*anymore. (#2869) -gcnow translates D names to C++ ones, e.g., to use the regular Visual Studio debugger (bypassing mago) and as preparation for VS Code debugging with Microsoft's C/C++ plug-in (screenshots). Thanks to Oleksandr for this contribution and the AA fix! (#2869)
- New command-line option
-fvisibility=hiddento hide functions/globals not marked asexport(for non-Windows targets), primarily to reduce the size of shared libraries. Thanks to Andrey for stepping up! (#2894, #2923) - Dropped support for LLVM 3.7 and 3.8. (#2872)
- LLVM for prebuilt packages upgraded to v7.0.1.
- Linux: now defaulting to
ld.goldlinker in general, not just with-flto=thin, as buggy olderld.bfdversions may wrongly strip out required symbols (change with-linker). (#2870) - Improved support for Android/x86[_64], musl libc and FreeBSD/AArch64. (#2917, ldc-developers/druntime#146)
- LDC-specific druntime:
ldc.simd.inlineIRmoved/renamed toldc.llvmasm.__ir(with deprecated legacy alias). (#2931) - New CMake option
COMPILE_D_MODULES_SEPARATELYbuilds D files in the DDMD frontend separately to reduce the time required to build LDC with many CPU cores and/or for iterative development. (#2914)
- Supports LLVM 3.9 - 7.0.
- Alpine linux/x64: built against Musl libc to support Docker images based on the Alpine distro, requires the
llvm5-libs,musl-dev,binutils-goldandgccpackages to build and link D apps and thetzdataandcurl-devpackages for certain stdlib modules.
- 32-bit Android/ARM regression introduced in v1.12. (#2892)

- Frontend, druntime and Phobos are at version 2.082.1. (#2818, #2837, #2858, #2873)
- Significant performance improvements for some transcendental
std.mathfunctions in single and double precision, at least for x86. (dlang/phobos#6272 (comment))
- Significant performance improvements for some transcendental
- Support for LLVM 7, which is used for the prebuilt packages. Due to an LLVM 7.0.0 regression, the prebuilt x86[_64] LDC binaries require a CPU with SSSE3, and so will your optimized binaries (unless compiling with
-mattr=-ssse3). (#2850) - JIT compilation: new
ldc.dynamic_compile.bindfunction with interface similar to C++std::bind, allowing to generate efficient specialized versions of functions (much like Easy::jit for C++). (#2726) - LTO now working for Win64 too; the prebuilt package includes the required external LLD linker and the optional LTO default libs. Enable as usual with
-flto=<thin|full> [-defaultlib=druntime-ldc-lto,phobos2-ldc-lto]. (#2774) - Config file: new
lib-dirsarray for directories to be searched for libraries, incl. LLVM compiler-rt libraries. (#2790)
- Supports LLVM 3.7 - 7.0.
- Windows: Supports Visual Studio/C++ Build Tools 2015 and 2017.
- Alpine linux/x64: built against Musl libc to support Docker images based on the Alpine distro, requires the
llvm5-libs,musl-dev, andgccpackages to build and link D apps and thetzdataandlibcurlpackages for certain stdlib modules. - Android/ARM: This release slightly changes the way emulated TLS is interfaced, but is missing a patch for 32-bit ARM. See the wiki for instructions on patching that file manually before cross-compiling the runtime libraries for 32-bit Android/ARM.

- Win32 breaking ABI change: add extra underscore for mangled names of D symbols. (#2598)
- No breaking ABI change for 64-bit macOS wrt. C++ mangling of D
(u)long. It's still mangled as C++(unsigned) longin order not to breaksize_tandptrdiff_tinterop, whereas DMD 2.079 mangles it as(unsigned) long long(which, in combination with missingcore.stdc.config.cpp_(u)long, makes it impossible to represent a C++ size_t/ptrdiff_t with DMD 2.079 on 64-bit macOS).
- Support for LLVM 6. It's used for the prebuilt packages, except for the 32-bit Windows package (due to #2629). (#2608)
- Integrated LLD (enable with
-link-internally) now also able to (cross-)link ELF and Mach-O binaries, in addition to the existing Windows COFF support. (#2203) - Prebuilt Linux and macOS packages now ship with LTO default libs (druntime & Phobos). Keep on using
-flto=<thin|full>to restrict LTO to your code, or opt for-flto=<thin|full> -defaultlib=phobos2-ldc-lto,druntime-ldc-ltoto include the default libs. (#2640) - When linking against shared default libs, LDC now sets a default rpath (absolute path to the LDC lib dir(s); configurable in the

-dip1008and-transition=<intpromote|16997>as well aspragma(crt_{con,de}structor). (#2486) - New switch
-link-defaultlib-sharedto link against shared druntime/Phobos. It defaults to true for shared libraries (-shared), so it's primarily useful for executables. (#2443) - Support for plugins via
-plugin=...(see this example). The mechanism is identical to Clang's LLVM-IR pass plugins and thus supports those as well, e.g., the AFLfuzz LLVM-mode plugin, Easy::Jit. (#2554) - Support for LLVM IR-based Profile-Guided Optimization via
-fprofile-{generate,use}(not working on Windows yet). (#2474) - Basic support for LLVM XRay instrumentation via
-fxray-{instrument,instruction-threshold}. (#2465) - DMD-style function trace profiling via
-profile(LDMD) /-fdmd-trace-functions(LDC). (#2477) - New UDA
ldc.attributes.assumeUsedto prevent a symbol from being optimized away. (#2457) - The PGO helper library
ldc-profile-rtwas replaced by LLVM's vanilla profiling library. Our subset of LLVM compiler-rt libraries is now also shipped on Windows (excl. fuzzer). (#2527, #2544) - Cherry-picked upstream Musl C runtime support for Docker images based on Alpine and added a native Alpine/x64 compiler, which requires the
llvm5,musl-dev, andgccpackages to run and link D apps and thetzdataandlibcurlpackages for certain stdlib modules.

- @joakim-noah's Android fixes have finally been fully incorporated, enabling every host to (cross-)compile to Android. (https://github.com/ldc-developers/llvm/commit/8655f3208cce28bb7f903cadf5f58a3911392bdc) Instructions on using this ldc release to cross-compile D apps for Android are on the wiki, including how to try out the native Android/arm package, ie a D compiler that you can run on your Android smartphone or tablet.
- Improved support for AddressSanitizer. LDC will automatically link with the AddressSanitizer runtime library when
-fsanitize=addressis passed (when LDC can find the AddressSanitizer library). - libFuzzer sanitizer support using
-fsanitize=fuzzer(same as Clang). This flag implies-fsanitize-coverage=trace-pc-guard,indirect-calls,trace-cmpand automatically links-in the runtime libFuzzer library if LDC can locate the runtime library. (With LLVM 4.0, there is a dependency on sanitizer runtime, so manually link the ASan library or use-fsanitize=fuzzer,address.) - New
-fsanitize-blacklist=<file>command-line option to exclude functions from sanitizer instrumentation (identical to Clang). The file must adhere to the textual Sanitizer Special Case List format. - New
-fsanitize-coverage=...command-line option with the same functionality as Clang. - The config file sections now feature an additional
post-switcheslist for switches to be appended to the command line (the existingswitcheslist is prepended). E.g., this now allows the user to override the directory containing the runtime libraries via-L-L/my/runtime/libsin the command line. (#2281)
- The
-sanitizecommand-line option has been renamed to-fsanitize*, for clang conformance. - The semantics of an empty
-conf=command-line option have been changed from 'use default config file' to 'use no config file'. - The binary representations of the init values for
float/double/realhave been unified to a special quiet NaN, with both most significant mantissa bits set, on all hosts and for all targets. (#2207)
- Supports LLVM 3.7 - 5.0. Support for 3.5 and 3.6 has been dropped.
- Windows: Supports Visual Studio/C++ Build Tools 2015 and 2017, incl. the latest Visual Studio 2017 Update 15.3.
- Consistent usage of a minimally tailored LLVM 4.0.1.
- Newly enabled LLVM target
NVPTXin order to target CUDA via DCompute. - Linux x86_64:

- Shipping with the LLVM LTO plugin for the
- Windows/MSVC: Build environment upgraded from Visual Studio 2015 Update 3 to Visual Studio 2017 15.3.3 (WinSDK 10.0.15063).
- Misc. debuginfo issues, incl. adaptations to internal LLVM 5.0 changes: (#2315)
refparameters and closure parameters declared with wrong address and hence potentially showing garbage.- Win64: parameters > 64 bit passed by value showing garbage.
- Win64: debuginfos for closure and nested variables now finally available starting with LLVM 5.0.
- LLVM error
Global variable initializer type does not match global variable type!forT.initwith explicit initializers for dominated members in nested unions. (#2108) - Inconsistent handling of lvalue slicees wrt. visible side-effects of slice lower/upper bound expressions. (#1433)
- Misc. dcompute issues. (#2195, #2215)
- Potential LDC crashes due to dangling pointers after replacing IR globals (required in some cases if the type contains unions) almost fully mitigated. (#1829)

- Addition of high-performant SemaphoreCI (incl. enabled LLVM/LDC assertions).
- CircleCI upgraded to 2.0, testing with latest gcc.
- Compile all D files for (non-unittest) druntime/Phobos at once. May be disabled via CMake option
COMPILE_ALL_D_FILES_AT_ONCE=OFF. (#2231)
- ThinLTO may not work well with the
ld.bfdlinker, useld.goldinstead (-Xcc=-fuse-ld=gold). - When building with LLVM 5.0, you may need
-DLDC_WITH_LLD=OFFin the CMake command line. Otherwise, if the LLD headers are available and LDC is built with LLD integration, the produced LDC binary will refuse to work due to conflicting command-line options.
- Frontend, druntime and Phobos are at version 2.073.2.
- A first experimental version of DCompute for OpenCL/CUDA targets has landed. See announcement.

- LDC now ships with static and shared runtime libs on supported platforms. (#1960)
- LLVM 3.9+: Static libraries are now generated by LDC (LLVM) by default, not by system
arorlib.exe. This means that LDC can cross-compile and -archive static libs for all supported targets. Command-line option-arallows specifying an external archiver to be used. (#2030) - New command-line options
-dip1000,-mvand-mscrtlib(#2041). - Ships with dlang tools rdmd, ddemangle and dustmite.

- Frontend, druntime and Phobos are at version 2.072.2.
- New function attribute
@ldc.attributes.allocSize(#1610), see https://wiki.dlang.org/LDC-specific_language_changes#.40.28ldc.attributes.allocSize.29
- Supports LLVM 3.5 - 4.0.
- Exception backtrace robustness has been significantly improved.
- Emission of
realswith differing precision to the host platform'srealhas been fixed.
(The compiler still uses the host platform's D real type to represent compile-time floating-point values, so parsing of literals and CTFE is restricted to the host real precision. For instance, LDC on AArch64 with its quad-precision reals would now make for a universal cross-compiler. On the other hand, cross-compiling from ARM to x86 with 80 bit reals still does not work – for example,real.maxwould silently overflow at compile-time and be emitted as 80-bit infinity.)
- Compilation error with DMD 2.074 host compiler.
- LLVM error when accessing

- Building LDC requires a preinstalled D compiler.
- Linux: Always build C parts of standard library as PIC (#2009). This makes the binary packages usable on Ubuntu 16.10 (where executables are linked as position-independent code by default, in contrast to the older system used for preparing the packages).
- Frontend, druntime and Phobos are at version 2.071.2.
- Link-Time Optimization (LTO) with
-flto={thin|full}(LLVM ≥ 3.9). LTO requires linker support and is therefore currently only supported on Linux (ld.goldwith LLVM plugin) and OS X. For more details, please refer to LLVM's and Clang's documentation, for example Clang's ThinLTO documentation. (#1840) - Experimental cross-module inlining (#1577, enable with

- Linking against LLVM shared library is now supported.
- Added support for LLVM 6.0 and 7.0. (ldc-developers#2600, ldc-developers#2825)
- Backported AArch64 fixes from master; most tests passing on Linux/glibc and Android. (ldc-developers#2575, ldc-developers#2811, ldc-developers/phobos#49, ldc-developers/phobos#50, ldc-developers/phobos#51, ldc-developers/phobos#52, ldc-developers/phobos#53, ldc-developers/phobos#54, ldc-developers/phobos#55, ldc-developers/phobos#56)
- Fix generation of debug info. (ldc-developers#2594)

core.stdc.stdarg.va_*functionsnothrowto enable compiling the 2.082 frontend. (ldc-developers#2821) - CI updates.
- Added LLVM 5.0 support.
- druntime: fixes for Android and addition of
core.math.yl2x[p1]()for x86(_64) targets. - dmd-testsuite: backported
runnable/cppa.dfix for GCC > 5. - CI updates.
- Added LLVM 4.0 support.
- Full stdlib and dmd testsuite passes on Android/ARM.
- Fixes for PPC64-LE, MIPS64 and ARM/AArch64 ABIs (#1905)
- Support for LLVM 3.5 - 3.9.
- Fixed soft float and hard float issues on ARM.
- Fixed ABI error on Linux/PPC and Linux/PPC64.
- Fixed error in
core.stdc.stdargon Linux/PPC and Linux/PPC64. - Fixed issue with
__tls_get_addron Linux/PPC and Linux/PPC64.
- ARM platform is now a first class target for LDC. It passes most test cases (except 2 failures) and can successfully compile the D version of the compiler.
- ARM platform is now fully supported. (#1283, #489)
- Preliminary support for AArch64.
- Preliminary support for LLVM 3.9.
- Inline assembly regression with local variable references. (#1292)
- Compile error on Linux/PPC and Linux/PPC64 due to missing import in Phobos.
- Linking against LLVM shared library is now supported.
- Frontend, druntime and Phobos are at version 2.068.2.
- The exception handling runtime now no longer allocates GC memory (although it still uses C
mallocif there are more than 8 concurrent exceptions or nestedfinallyblocks per thread). Note: Creating theThrowables in user code (e.g.new Exception("…")) and theRuntime.traceHandlermay GC-allocate still. (Thanks for this goes to our newest contributor, @Philpax). - The
@ldc.attributes.section("…")attribute can now be used to explicitly specify the object file section a variable or function is emitted to. - The
@ldc.attributes.target("…")attribute can now be used to explicitly specify CPU features or architecture for a function. - The
-staticoption can be used to create fully static binaries on Linux (akin to the GCC option of the same name). core.atomic.atomicOp()now exploits LLVM read-modify-write intrinsics instead of using a compare-and-swap loop. As side-effect, the atomic intrinsics in moduleldc.intrinsicshave been renamed:llvm_atomic_cmp_swap=>llvm_atomic_cmp_xchgllvm_atomic_swap=>llvm_atomic_rmw_xchgllvm_atomic_load_*=>llvm_atomic_rmw_*
- Improved ARM support. (#1280)
- The compiler now supports NetBSD. (#1247) (Thanks for this goes to @nrTQgc.)
- The float ABI can now be derived from the second field of the triple. E.g. the hardfloat ABI is used if triple
armv7a-hardfloat-linux-gnueabiis given. (#1253) - Support for fibers on AArch64.
- Support for LLVM 3.8 and preliminary support for LLVM 3.9
- make install problem. (#1289)

- Can't build gtk-d 3.1.4. (#1112)
- x86 ABI: Fix Solaris regression and work around MSVC byval alignment issue. (#1230)
- Atomic RMW operations emit subpar x86 assembly. (#1195)
- align() not respected for local variable declarations. (#1154)
- Codegen optimizations are no longer disabled when
-gis given. (75b3270a) - Debug information is now generated for
refandoutparameters. (#1177) core.internal.converttests do not depend onrealpadding bytes any longer. (#788)
- LDC now requires LLVM 3.5–3.8 and thus also a C++11-capable compiler to build.
- The LDC-specific parts of the source code have received a big overhaul to make use of some C++11 features and to unify the style (the LLVM style as per
clang-formatis now used). - The groundwork for a code generation test suite working on the LLVM IR level has been laid, together with some first test cases for alignment issues.
- LDC now emits more optional LLVM IR attributes for more optimization opportunities. (#1232)
- LDC does not zero the padding area of a real variable. This may lead to wrong results if the padding area is also considered. See #770. Does not apply to real members inside structs etc.
- Phobos does not compile on MinGW platform.
