Note that this problem does not occur on arm-elf... I have somewhat reduced the testcase, and included it. I've verified that the backtrace of the crash of the new testcase is the same to that of the old one (well, almost completely the same). Looks like move2add_note_store is getting passed NULL data from note_stores, and that in turn is getting NULL data from reload_cse_move2add. Hope this information is helpful to someone :-) Dara Backtrace: 0x00237b9c in move2add_note_store (dst=0xe7b0c0, set=0xe79654, data=0x0) at reload1.c:9293 9293 reg_set_luid[REGNO (XEXP (dst, 0))] = 0; (gdb) bt #0 0x00237b9c in move2add_note_store (dst=0xe7b0c0, set=0xe79654, data=0x0) at reload1.c:9293 #1 0x001c6afc in note_stores (x=0xe79654, fun=0x237a64 , data=0x0) at rtlanal.c:1637 #2 0x002379b0 in reload_cse_move2add (first=0xe2b8f0) at reload1.c:9249 #3 0x00233c28 in reload_cse_regs (first=0xe2b8f0) at reload1.c:8154 #4 0x000b0ecc in rest_of_compilation (decl=0xe62620) at toplev.c:3335 #5 0x00020670 in c_expand_body (fndecl=0xe62620, nested_p=0, can_defer_p=1) at c- decl.c:6567 #6 0x00020250 in finish_function (nested=0, can_defer_p=1) at c-decl.c:6407 #7 0x00003bf4 in yyparse () at c-parse.y:403 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
