Remove unnecessary argument. Replace it with this: * cse.c (count_reg_usage): In INSN, JUMP_INSN and CALL_INSN cases, if flag_non_call_exceptions is set and the insn may trap, pass pc_rtx as dest for recursion. In SET_SRC part of SET case, if dest is already set, pass it down unchanged. 2005-07-15 J"orn Rennecke <[EMAIL PROTECTED]> PR rtl-optimization/21848 http://gcc.gnu.org/ml/gcc-patches/2005-07/msg01142.html * calls.c (emit_library_call_value_1): For const functions, add USEs of the stack slots to CALL_INSN_FUNCTION_USAGE. 2005-07-15 J"orn Rennecke <[EMAIL PROTECTED]> PR rtl-optimization/20370 http://gcc.gnu.org/ml/gcc-patches/2005-07/msg01148.html * ifcvt.c (dead_or_predicable): Before calling propagate_block, call allocate_reg_info if necessary.
