The following code causes an ICE when compiled with "gcc -march=athlon -O -c": --------------------------snip here---------------------- void foo () { int i, n; for ( i=0; i<n; ++i ) i=n^128; } --------------------------snip here---------------------- The error message is: bug.c: In function `foo': bug.c:7: error: unrecognizable insn: (insn 53 57 54 1 (nil) (parallel [ (set (strict_low_part (reg:QI 0 al [58])) (xor:QI (reg:QI 0 al [58]) (const_int -128 [0xffffff80]))) (clobber (reg:CC 17 flags)) ]) -1 (insn_list 57 (nil)) (expr_list:REG_UNUSED (reg:CC 17 flags) (nil))) bug.c:7: internal compiler error: Internal compiler error in extract_insn, at recog.c:2130 Please submit a full bug report, [etc.] The example compiles fine with gcc 3.1. The example was created from a file (psout.i) from a bug report of Sergei Pachkov (see PR 7063). Release: gcc 3.2 20020617 Environment: i686-pc-linux-gnu How-To-Repeat: gcc -march=athlon -O -c bug.c
