The code fragment below causes an ICE if k = 1. No ICE occurs if k = 0 or the optimization level is -O0 or -O1. troutmask:kargl[205] gcc -O2 -c c.c c.c: In function `ice': c.c:11: unrecognizable insn: (insn 179 170 188 (set (reg:SI 85) (ashift:SI (reg/v:SI 62) (const_int 1 [0x1]))) -1 (nil) (nil)) c.c:11: Internal compiler error in extract_insn, at recog.c:2150 Please submit a full bug report, with preprocessed source if appropriate.
