LDC 1.38.0-beta1

Big news

• Frontend, druntime and Phobos are at version 2.108.0+. (#4591, #4615, #4619, #4622, #4623)
• Support for LLVM 18. The prebuilt packages use v18.1.3 (except for macOS arm64). (#4599, #4605, #4607, #4604)
• 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)

Platform support

• Supports LLVM 11 - 18.

Bug fixes

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

LDC 1.37.0

Big news

• Frontend, druntime and Phobos are at version 2.107.1. (#4563, #4577, #4587)

Bug fixes

• Fix if-statement elision on constant true/false condition. (#4556, #4559)

LDC 1.36.0

(Changes since 1.36.0-beta1 are marked with (new).)

Big news

• Frontend, druntime and Phobos are at version 2.106.1. (#4522, #4539, #4551) (new)
• Support for LLVM 17. The prebuilt packages use v17.0.6. (#4533, #4540)
• New command-line options -fno-{exceptions,moduleinfo,rtti} to selectively enable some -betterC effects. (#4522)
• New command-line option -fprofile-sample-use for using sample-based profile data for optimization. Functionality and usage is identical to Clang's option with same name. (#4531)
• New ldc-profgen tool for sample-based PGO, a copy of LLVM's llvm-profgen. (#4536)

Platform support

• Supports LLVM 11.0 - 17.0.

Big news

• Frontend, druntime and Phobos are at version 2.105.2+. (#4476, #4498, #4513) (new)
• The Windows installer now supports non-admin installs without an explicit /CURRENTUSER switch. (#4495) (new)

Platform support

• Initial compiler support for LoongArch64. druntime support is pending. (#4500) (new)

Bug fixes

• ImportC:
  • Fix static linkage. (#4484, #4487) (new)
  • Make gcc builtins available. (#4483) (new)
  • Apple: Support weird asm("_" "<name>") mangling stuff. (#4485, #4486) (new)
• AArch64: Fix an ABI-related ICE. (#4489, #4490) (new)
• Fix GC2Stack optimization regression introduced in v1.24. (#4510, #4511) (new)
• Fix druntime ABI divergence when compiling with sanitizers support. (#4508, #4509) (new)
• Windows: Fix an instance of missed backslash-escaping in -ftime-trace JSON. (#4506, #4507) (new)

LDC 1.35.0-beta1

• Frontend, druntime and Phobos are at version 2.105.1+. (#4476)

LDC 1.34.0

(Changes since 1.34.0-beta2 are marked with (new).)

Big news

• Frontend, druntime and Phobos are at version 2.104.2. (#4440)
• 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=1000000000 in etc/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).

Platform support

• Supports LLVM 11.0 - 16.0. Support for LLVM 9 and 10 was dropped.
• 64-bit RISC-V: Now defaults to -mattr=+m,+a,+f,+d,+c ('rv64gc' ABI) for non-bare-metal targets, i.e., if the target triple includes a valid operating system. (#4390) (new)

Bug fixes

• Fix function pointers/delegates on Harvard architectures (e.g., AVR). (#4432, #4465)
