Author: jakub Date: Thu Jan 15 08:07:38 2009 New Revision: 143387 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=143387 Log: PR rtl-optimization/38245 * calls.c (expand_call): Add stack arguments to CALL_INSN_FUNCTION_USAGE even for pure calls (when ACCUMULATE_OUTGOING_ARGS) and even for args partially passed in regs and partially in memory or BLKmode arguments. (emit_library_call_value_1): Add stack arguments to CALL_INSN_FUNCTION_USAGE even for pure calls (when ACCUMULATE_OUTGOING_ARGS). * dce.c: Include tm_p.h. (find_call_stack_args): New function. (deletable_insn_p): Call it for CALL_P insns. Add ARG_STORES argument. (mark_insn): Call find_call_stack_args for CALL_Ps. (prescan_insns_for_dce): Walk insns backwards in bb rather than forwards. Allocate and free arg_stores bitmap if needed, pass it down to deletable_insn_p, don't mark stores set in arg_stores bitmap, clear the bitmap at the beginning of each bb. * Makefile.in (dce.o): Depend on $(TM_P_H). * gcc.dg/pr38245-3.c: New test. * gcc.dg/pr38245-3.h: New file. * gcc.dg/pr38245-4.c: New file. * gcc.dg/pr38364.c: New test.
