--- Comment #3 from Martin Liška <marxin at gcc dot gnu.org> ---
The issue is that it uses always_inline for a function that uses -msse3 and you
use -march=native and -mtune=generic.
If I configure postgres with :
CFLAGS="-mtune=generic -march=x86-64"
CXXFLAGS=...
LDFLAGS=...
then it builds fine. The file should not be built with the flags.
Clang has nicer error message:
error: always_inline function '_mm_crc32_u64' requires target feature 'ssse3',
but would be inlined into function 'pg_comp_crc32c_sse42' that is compiled
without support for 'ssse3'
