LDC 1.40.1-beta1

Big news

• Frontend and druntime bumped to version 2.110.0 final. (#4854, #4868)
• LLVM for prebuilt packages bumped to v19.1.7. (#4822)
• New prebuilt package for Alpine Linux x86_64 with musl libc. It's currently generated on Alpine v3.21, using its default LLVM 19. Most bundled executables are fully static and can be run on ~all distros. (#4826, #4862)
• Revived dynamic-compile (JIT) functionality (formerly unsupported since LLVM 12), supporting LLVM 18+ now. (#4774)
• ldc2.conf: %%ldcversion%% placeholder added, allowing to refer to version-specific directories.
• Windows: The prebuilt packages now bundle an official libcurl build (from https://curl.se/windows/), currently v8.12.1. The static library (curl_a.lib) isn't available anymore. (#4855)

Platform support

• Supports LLVM 15 - 19.
• Initial compiler and runtime support for ppc64 and ppc64le systems that use IEEE 754R 128-bit floating-point as the default 128-bit floating-point format. (#4833, #4840)
• Initial support for Windows on ARM64. The prebuilt Windows multilib package/installer bundles prebuilt arm64 druntime and Phobos; cross-compiling works out of the box via -mtriple=aarch64-windows-msvc, but you currently need to set up a suited MSVC arm64 build environment before yourself (e.g., by running vsdevcmd.bat -arch=arm64 -host_arch=x64). (#4835, #4846)

Bug fixes

• Prebuilt macOS universal package: Fix automatic bundled libLTO.dylib usage when linking with LTO. (#4857)
• Building multi-file D applications with control-flow protection will no longer cause LDC to throw an internal compiler error. (#4828)

LDC 1.40.0

(No relevant changes since 1.40.0-beta6.)

Big news

• Frontend, druntime and Phobos are at version ~2.110.0. (#4707, #4737, #4749, #4768, #4784, #4792, #4798)
• Support for LLVM 19. The prebuilt packages use v19.1.3 (incl. macOS arm64). (#4712, #4735, #4763, #4772)
• Objective-C: The compiler now properly supports Objective-C classes and protocols, as well as swift stub classes (via the @swift UDA). (#4777)
• Android: NDK for prebuilt package bumped from r26d to r27c. (#4711, #4772)
• 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)

Platform support

• Supports LLVM 15 - 19.

Bug fixes

• Fix potentially corrupt IR layouts for bit fields. (#4646, #4708)
• Fix potentially corrupt IR layouts for explicitly under-aligned aggregates, a regression introduced in LDC v1.31. (#4734, #4736)
• ELF: Emit (most) instantiated symbols in COMDATs for proper link-time culling. (#3589, #4748)
• Support scalar right-hand-sides when bit-shifting vectors. (#3606, #4781)
• Fix LLVM data layout for the SPIR-V target used in D-Compute on LLVM 19+. (#4772)
