Big news

Frontend, druntime and Phobos are at version2.084.1, incl. new command-line options-mixin,-{enable,disable}-switch-errorsand-checkaction. (#2946, #2977, #2999)(new)Options-release,-d-debugand-unittestdon't override preceding, more specific options (-{enable,disable}-{asserts,invariants,preconditions,postconditions,contracts}) anymore.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 optionRT_SUPPORT_SANITIZERS=ON). (#2975, ldc-developers/druntime#152)(new)Supportpragma(LDC_extern_weak)for function declarations - if the function isn't available when linking, its address is null. (#2984)(new)

Platform support

Supports LLVM 3.9 - 7.0.

Bug fixes

Fix C++ mangling regression for functions with multiplerealparameters 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)Avoid crashes with-allinst(fix emission of only speculatively nested functions). (#2932, #2940)Fix XRay support for LLVM 7+. (#2965)AArch64: Fix DMD-style profile measurements. (#2950)Be less picky about placement of pragmas (allow intermediateextern(C)etc.). (#2599)MSVC: FixrealC++ mangling to match Visual C++long double. (#2974)Fix bad ICE noticed when building protobuf-d. (#2990, #2992)(new)Fix ICE when directly indexing vector return value. (#2988, #2991)(new)Fix identity comparisons of complex numbers. (#2918, #2993)(new)MIPS32 fix forcore.stdc.stdarg. (#2989, ldc-developers/druntime#153)(new)Fixcore.atomic.cas()for 64-bit floating-point values. (#3000, #3001)(new)beta1 regression: 'Instruction does not dominate all uses' (#2996, #2997)(new)

Known issues

Buggy olderld.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.LDC does not zero the padding area of arealvariable. This may lead to wrong results if the padding area is also considered. See #770. Does not apply torealmembers inside structs etc.
