We already have a LICENSE file that covers the Zig Standard Library. We
no longer need to remind everyone that the license is MIT in every single
file.
Previously this was introduced to clarify the situation for a fork of
Zig that made Zig's LICENSE file harder to find, and replaced it with
their own license that required annual payments to their company.
However that fork now appears to be dead. So there is no need to
reinforce the copyright notice in every single file.
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.
