And add std.math.f128_* constants. The routines are: __fixdfdi, __fixdfsi, __fixdfti, __fixsfdi, __fixsfsi, __fixsfti, __fixtfdi, __fixtfsi, __fixtfti. These all call fixint which is a generic zig function that does the conversion: pub fn fixint(comptime fp_t: type, comptime fixint_t: type, a: fp_t) fixint_t There are also a set tests: __fixdfdi_test, __fixdfsi_test, __fixdfti_test, __fixsfdi_test, __fixsfsi_test, __fixsfti_test, __fixtfdi_test, __fixtfsi_test, __fixtfti_test. |

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.
