We encounter the following error in 177.mesa from SPEC2000 with the 2013.05 64-bit toolchain when fast math is used.

eval.c: In function ‘gl_GetMapiv’:
eval.c:1787:14: internal compiler error: in emit_move_insn, at expr.c:3486

Thank you for the bug report. I had confirmed it with 2013.05.

Root cause: Wrong MODE is used to force_reg for operands[5] in function gen_aarch64_vcond_internalv4si.

2013.06 had fixed it.

The buggy code was not in FSF 4.8 and FSF trunk had fixed it.
