Big news
- Frontend, druntime and Phobos are at version 2.093.0+, incl. new command-line option
-vtemplates. (#3476) - Min required LLVM version raised to v6.0, dropping support for v3.9-5.0. (#3493)
- 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)
Platform support
- Supports LLVM 6.0 - 10.0.
Bug fixes
- 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)
Internals
- 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)
Known issues
- 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)
- 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. - LDC does not zero the padding area of a
realvariable. This may lead to wrong results if the padding area is also considered. See #770. Does not apply torealmembers inside structs etc.
