Author: jakub Date: Tue Sep 8 09:25:47 2009 New Revision: 151500 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=151500 Log: PR rtl-optimization/41239 * sched-int.h (struct deps): Add last_function_call_may_noreturn field. * sched-rgn.c (deps_join): Join also last_function_call_may_noreturn lists. * sched-deps.c (sched_analyze_insn): Prevent moving trapping insns across calls, as the calls might not always return normally. (call_may_noreturn_p): New function. (deps_analyze_insn): Update last_function_call_may_noreturn list. (init_deps): Initialize it. (remove_from_deps): Also remove calls from last_function_call_may_noreturn list. * gcc.c-torture/execute/pr41239.c: New test.
