Bug 388835 – [ICE/4.5/4.6/4.7] arch/x86/crypto/aesni-intel_glue.c:221:1: internal compiler error: in move_insn, at haifa-sched.c:2314

Linux .config producing ICE with gcc 4.5.3

Building Linux 3.0.4 with gcc-4.5.3 results in an ICE:

arch/x86/crypto/aesni-intel_glue.c: In function 'aes_decrypt':
arch/x86/crypto/aesni-intel_glue.c:221:1: internal compiler error: in move_insn, at haifa-sched.c:2314

Older kernels (i.e. 2.6.39) are affected, too.

gcc-4.4.5 works fine.

The error can also be avoided by enabling CONFIG_CC_OPTIMIZE_FOR_SIZE.

run in your kernel dir:
  make arch/x86/crypto/aesni-intel_glue.o

if that fails, run:
  make arch/x86/crypto/aesni-intel_glue.o V=1 >& log
  make arch/x86/crypto/aesni-intel_glue.i

and then post the "log" and "arch/x86/crypto/aesni-intel_glue.i" files as attachments

[Comment 4 SpanKY 2011-11-03 18:36:45 UTC]

thanks, i can reproduce with your test cases now

just need someone to open a PR upstream ;)

[Comment 7 Roger Luethi 2011-11-12 13:41:23 UTC]

Alright, it's at:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51106

Thanks!

[Comment 8 SpanKY 2011-12-06 23:52:08 UTC]

i don't have perms on the gcc bugzilla, but you'll want to edit the bug and add:
  Known to fail: 4.5.3 4.6.2 4.7-20110827
  Known to work: 4.3.6 4.4.5
  Target: i686-pc-linux-gnu
  Host: i686-pc-linux-gnu

[Comment 9 Roger Luethi 2011-12-07 07:05:23 UTC]

The gcc bugzilla won't let me add 4.7-20110827 ("4.7 [...] is not a valid version"), but the rest is there now.
