This compiler-rt library is ported from [LLVM](http://compiler-rt.llvm.org/).
|
||
|
|
|
||
|
|
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.
