android-native-tools

In continuation to search a working llc.exe on Windows, we go back to 18.1.6 as we know that version, from an earlier release, works well. The only change, in relation to the previous 18.1.6 release, is the addition of llvm-objcopy to packaging.

The latest upstream release in the 18 series. There are no changes in it that affect us directly, but we've noticed that llc.exe from 18.1.7 crashes with an access violation on Windows CI bots and we hope to see the crash gone with this version.

What's Changed

The LLVM release doesn't contain any changes that affect us directly, we're updating the version just to
track the latest release.

However, taking this opportunity to add llvm-objcopy to the set of tools - it will be used at some point
to separate debugging information from the shared libraries we build at application build time.

LLVM 18.1.3 is out.

Changes: https://discourse.llvm.org/t/llvm-18-1-0-released/77448
Changes: https://discourse.llvm.org/t/llvm-18-1-1-released/77540
Changes: https://discourse.llvm.org/t/18-1-2-released/77821
Changes: https://discourse.llvm.org/t/18-1-3-released/78136

Changes interesting for us:

• AArch64 backend
  • Added support for Cortex-A520, Cortex-A720 and Cortex-X4 CPUs.
  • Assembler/disassembler support has been added for 2023 architecture extensions.
  • Support has been added for Stack Clash Protection. During function frame creation
    and dynamic stack allocations, the compiler will issue memory accesses at regular
    intervals so that a guard area at the top of the stack can’t be skipped over.
• x86 backend
  • The i128 type now matches GCC and clang’s __int128 type. This mainly benefits external
    projects such as Rust which aim to be binary compatible with C, but also fixes code
    generation where LLVM already assumed that the type matched and called into libgcc
    helper functions.
