* builtins.c: (expand_builtin_memset): Rewrite to support 'set_storage_via_setmem'. * expr.c: (enum insn_code setmem_optab): Define. (enum insn_code clrmem_optab): Remove. (set_storage_via_setmem): New function. (clear_storage_via_setmem): Remove. (clear_storage): Replace call to "clear_storage_via_clrmem" with "set_storage_via_setmem". * expr.h: (set_storage_via_setmem): Declare. (CLEAR_RATIO): Redefine using HAVE_setmemM. * optabs.h: (enum insn_code setmem_optab): Declare. (enum insn_code clrmem_optab): Remove. * optabs.c: (init_optabs): Initialize setmem_optab. (enum insn_code clrmem_optab): Remove. * genopinit.c: (otabs): Likewise. * doc/md.texi: Document new standard pattern 'setmem'. Remove 'clrmem'. * config/alpha/alpha.c: (alpha_expand_block_clear): Adjust 'operands' ordering. * config/frv/frv.c: (frv_expand_block_clear): Likewise. * config/rs6000/rs6000.c: (expand_block_clear): Likewise. * config/alpha/alpha.md: ("clrmemqi", "clrmemdi"): Rename to "setmemM". FAIL on operands[2]!=const0_rtx. Adjust 'operands' ordering. * config/avr/avr.md: ("clrmemhi"): Likewise. * config/frv/frv.md: ("clrmemsi"): Likewise. * config/i386/i386.md: ("clrmemsi", "clrmemdi"): Likewise. * config/pa/pa.md: ("clrmemsi", "clrmemdi"): Likewise. * config/rs6000/rs6000.md: ("clrmemsi"): Likewise. * config/s390/s390.md: ("clrmem<mode>"): Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@101386 138bc75d-0d04-0410-961f-82ee72b054a4
