LDC 1.40.0-beta4

(Changes since 1.40.0-beta3 are marked with (new).)

Big news

• Frontend, druntime and Phobos are at version ~2.110.0. (#4707, #4737, #4749, #4768) (new)
• 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)
• Add support for building against a system copy of zlib through -DPHOBOS_SYSTEM_ZLIB=ON. (#4742)
• Emscripten: The compiler now mimicks a musl Linux platform wrt. extra predefined versions (linux, Posix, CRuntime_Musl, CppRuntime_LLVM). (#4750)

Bug fixes

LDC 1.39.0

(Changes since 1.39.0-beta1 are marked with (new).)

Big news

• Frontend, druntime and Phobos are at version 2.109.1. (#4660, #4692) (new)
• LLVM for prebuilt packages bumped to v18.1.6 (except for macOS arm64). (#4678)
• Added CI testing of Alpine Linux with musl libc (including some bug fixes). Removed the libunwind dependency when linking with musl libc. (#4650, #4691) (new)

Platform support

• Supports LLVM 15 - 18. Support for LLVM 11 - 14 was dropped. The CLI options -passmanager and -opaque-pointers were removed.

LDC 1.38.0

(Changes since 1.38.0-beta1 are marked with (new).)

Big news

• Frontend, druntime and Phobos are at version 2.108.1. (#4591, #4615, #4619, #4622, #4623, #4640) (new)
• Support for LLVM 18. The prebuilt packages use v18.1.5 (except for macOS arm64). (#4599, #4605, #4607, #4604, #4628, #4642) (new)
• 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.

Platform support

• Supports LLVM 11 - 18.

Bug fixes

• Android: Support the lld linker. (#3918)
