"""LLVM libc starlark rules for tests.
|
|
|
|
libc functions are created though the libc_build_rules.bzl:libc_function.
|
|
They come in two flavors:
|
|
- the internal one that is scoped into the `LIBC_NAMESPACE` namespace.
|
|
- the libc one that is the regular C function.
|
|
|
|
When performing tests we make sure to always use the internal version.
