History
LemonBoy d03e9d0b83 compiler-rt: Fix f16 API declarations to be consistent 
LLVM and compiler-rt must agree on how the parameters are passed, it
turns out that in LLVM13 something changed and broke the test case for
AArch64 systems.

It has nothing to do with fma at all.

Closes #9900

README.md

This compiler-rt library is ported from LLVM.

It's needed because LLVM emits library calls to compiler-rt when hardware lacks functionality, for example, 64-bit integer multiplication on 32-bit x86.

This library is automatically built as-needed for the compilation target and then statically linked and therefore is a transparent dependency for the programmer.

Any bugs should be solved by trying to duplicate the bug upstream.

  • If the bug exists upstream, get it fixed with the LLVM team and then port the fix downstream to Zig.
  • If the bug only exists in Zig, something went wrong porting the code, and you can run the C code and Zig code side by side in a debugger to figure out what's happening differently.
