Bug#1022169: llvm-toolchain-15: FTBFS on mips*el: static assertion failed: struct_kernel_stat_sz == sizeof(stat)

[Simon McVittie]

Source: llvm-toolchain-15
Version: 1:15.0.2-1
Severity: serious
Tags: ftbfs
Justification: fails to build from source, making mesa unbuildable
User: debian-mips at lists.debian.org
Usertags: mipsel mips64el
X-Debbugs-Cc: debian-mips at lists.debian.org, mesa at packages.debian.org
Control: affects -1 + src:mesa

Quoting from mips64el buildd logs, but mipsel has a similar failure:

> /<<PKGBUILDDIR>>/compiler-rt/lib/sanitizer_common/sanitizer_platform_limits_linux.cpp:67:1: error: static assertion failed due to requirement 'struct_kernel_stat_sz == sizeof(stat)':
> COMPILER_CHECK(struct_kernel_stat_sz == sizeof(struct stat));

Strictly speaking this is not a regression because llvm-toolchain-15 was
never built successfully on mips*el, but I think it should be treated as
RC anyway, because older llvm-toolchain-* were buildable on mips*el (and
mesa is already using llvm-toolchain-15, making it a key package).
