This lays the groundwork for #2879. This library will be built and linked when a static libc is going to be linked into the compilation. Currently, that means musl, wasi-libc, and MinGW-w64. As a demonstration, this commit removes the musl C code for a few string functions and implements them in libzigc. This means that those libzigc functions are now load-bearing for musl and wasi-libc. Note that if a function has an implementation in compiler-rt already, libzigc should not implement it. Instead, as we recently did for memcpy/memmove, we should delete the libc copy and rely on the compiler-rt implementation. I repurposed the existing "universal libc" code to do this. That code hadn't seen development beyond basic string functions in years, and was only usable-ish on freestanding. I think that if we want to seriously pursue the idea of Zig providing a freestanding libc, we should do so only after defining clear goals (and non-goals) for it. See also #22240 for a similar case. |
