Bug 434852 – [ICE/4.5] sys-devel/gcc-4.5.2 crashes while building llvm in extract_insn, at recog.c:2103 (unrecognizable insn)

• Status: RESOLVED NEEDINFO
• Product: Gentoo Linux

[Description Wei-Ren Chen 2012-09-13 03:16:40 UTC]

I am compiling LLVM trunk on Gentoo (gcc 4.5.2), but seems it failed due to some GCC issues. See more details on attachment.

post `emerge --info` in all your bug reports

also, find the exact gcc command that is being run (post it here), change the '-c' to '-E', and then attach the output of running that command.

  done. The output of `gcc -E` is out of the 1MB limit, so I submit a tarball.

  Note, I also alias gcc to gcc-4.6.2, and has the same error as gcc-4.5.2.

The attachment "output of `gcc -E`" only contains garbage.

Previous one contains garbage.

Thanks. We need the exact gcc command flags that you use.
Please post the output of "make VERBOSE=1".

I cannot reproduce this ICE with vanilla 4.6.3 or 4.7 or 4.8.

  4.5.4 and 4.6.3 are O.K. Maybe it's 4.5.2 and 4.6.2's problem?
