Hello,This patch fixes a couple of places where code motion machinery wrongly attempts to re-use a pointer to the last insn in a BB after control flow following that BB has been changed (so the last jump might have been removed or replaced). This is not too frequent, so the solution is to simply recompute the last instruction if we notice the CFG change. Bootstrapped and regtested on x86_64-linux together with other recently submitted sel-sched fixes; OK for trunk? (I forgot to mention this in two other e-mails; sorry). 2011-04-07 Dmitry Melnik<d...@ispras.ru> PR rtl-optimization/48235 * sel-sched.c (code_motion_process_successors): Recompute the last insn in basic block if control flow changed. (code_motion_path_driver): Ditto. Recompute the first insn as well. Update condition for ilist_remove. testsuite: gcc.dg/pr48235.c: New.
Ok, thanks.
