The bug can be reproduced with the following code snippet: -------------------------snip here----------------------- void foo() { unsigned int i, j; j = (i >> 0xf0); } -------------------------snip here----------------------- Compiling this with gcc-3.2.1-prerelease (or mainline) on i686-pc-linux-gnu I get: PR8588.c: In function `foo': PR8588.c:4: warning: right shift count >= width of type PR8588.c:5: unrecognizable insn: (insn 10 20 12 (set (reg:QI 58) (const_int 240 [0xf0])) -1 (nil) (nil)) PR8588.c:5: Internal compiler error in extract_insn, at recog.c:2148 Please submit a full bug report, [etc.] The code compiled fine under gcc 3.0.x, therefore we have a regression. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=8588
