Agreed.

We x86 arch maintainers definitely do not ignore warnings from the assembler. 
Assembler warnings were pretty good historically and seldom produce false positives.

Most of those are -Wunused-but-set-variable warnings, right? I'm definitely not 
ignoring the ones that affect the code i maintain - so they are very much useful.

But if GCC broke the build unnecessarily, just to over-eagerly warn about something 
that worked fine before, that would be extremely counter-productive! In such a 
situation the Linux kernel project would likely be fed up enough to build its own 
sane compiler/assembler/linker combo and would aim to become entirely independent in 
terms of its build environment.

Thanks,
