* add u3, u4, u5, u6, u7 and i3, i4, i5, i6, i7
* shift operations shift amount parameter type is
integer with log2 bit width of other param
- This enforces not violating undefined behavior on
shift amount >= bit width with the type system
* clean up math.log, math.ln, math.log2, math.log10
closes #403
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.
