Re: can't build x86-32 libc on x86-64 with mainline binutils


Hi Alex,

Anyhow, here's the testcase:

.tfloat 0.3465735902799726547086160

Ah ha - difficult to reproduce but yes I now get:


  foo.s: Assembler messages:
  foo.s:1: Fatal error: failed sanity check

Note - this bug does not seem to have stopped me from building gcc with the mainline sources, but then I am not configuring with glibc in the same way as you and there are probably some other differences in our build environments as well.

I assume however that this must be a gcc bug - ie it has miscompiled gas. Have you investigated further yet ?

Cheers
  Nick
