vegecode c24a49a1a7 Fixes to divsf3 (#2186) 
* Fixes to divsf3

Embarrassingly failed to notice a section that was unchanged from where
it was copied from mulXf3.zig. The test cases for this function series
div{s,d,t}f3 are very incomplete and don't exercise all code paths.

Remove unnecessary switch from divsf3 left during development from when
I tried to make it generic to support f32, f64, and f128 in one go.

Make runtime safety dependent on whether a test is being run.

* divsf3: switch plus to minus

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.
