/tools/linux/gcc-4.1.0/bin/g++ -c ice.i
tmp.f_000000.cxx: In member function 'void
CarbonDesignSystems__design::c_top::f_$block_selfcycle3_v_L7_253_()':
tmp.f_000000.cxx:26432: error: unrecognizable insn:
(insn 176 175 177 12 (set (reg:QI 119)
(const_int 128 [0x80])) -1 (nil)
(nil))
tmp.f_000000.cxx:26432: internal compiler error: in extract_insn, at
recog.c:2084
P
I don't understand why the instruction recogizer doesn't match the '*movqi_1'
pattern in expectation of generating a 'movb #128,pseudo119'
