I have attached code, hopefully suitable for a testsuite item, derived from gcc/gcc/find-reloads.c. Compiling this with -m<any k6 option> -Os causes an ICE. A loop insn is generated (compiling with say -mi586 generates a jump insn instead), the target of which is outside of the +/-127 range of the loop. Release: 3.2.2 Environment: not significant How-To-Repeat: run the attached file with -m<any k6 option> -Os
State-Changed-From-To: open->analyzed State-Changed-Why: Confirmed on 3.2 branch. 3.3 and mainline are not affected.
Responsible-Changed-From-To: unassigned->ebotcazou Responsible-Changed-Why: Already fixed something very similar.

Please correct me if I'm wrong. At present I can't get either one. I'm still getting: cvs server: Updating gcc cvs server: [10:47:02] waiting for anoncvs's lock in /cvsroot/gcc/gcc I haven't seen that before, and don't know what is going on there. I'll try again later and hope it clears. I'd like to build and test whatever branch/release you checked in to, and then advise Martin the Gentoo GCC guy to pick it up.
