* rtlanal.c (insn_rtx_cost): New function, moved and renamed from combine.c's combine_insn_cost. * rtl.h (insn_rtx_cost): Prototype here. * combine.c (combine_insn_cost): Delete function. (combine_validate_cost): Update callers of combine_insn_cost to call insn_rtx_cost instead. (combine_instructions): Likewise. Use NONJUMP_INSN_P to avoid requesting the rtx_cost of call and/or jump instructions. * ifcvt.c (total_bb_rtx_cost): Use insn_rtx_cost instead of calling rtx_cost directly. Don't request/use the cost of call or jump instructions. Return -1 if the cost of any instruction can't be determined (or the BB contains a function call). (find_if_case_1): Abort transformation if total_bb_rtx_cost returns -1 (i.e. can't determine the cost of any instruction or the basic block contains a subroutine call). (find_if_case_2): Likewise.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
