History
Andrew Kelley c86589a738 disable f128 compiler_rt tests failing on windows 
These were never working with native CPU features. In this branch,
we fix native CPU features not being enabled on Windows, and regress
f128 language features. In the llvm10 branch, all this is fixed,
and the tests are re-enabled.

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.
