When the file shade.i from stress-1.17 is compiled using the options:
-O2 -m4
the following error occurs:
shade.i
shade.i: In function `gl_color_shade_vertices':
shade.i:6106: error: unrecognizable insn:
(insn:HI 1078 1016 753 42 (nil) (set (reg/v:SF 486)
(reg:SF 614)) -1 (nil)
(expr_list:REG_DEAD (reg:SF 614)
(expr_list:REG_EQUAL (reg:SF 614)
(nil))))
shade.i:6106: internal compiler error: Internal compiler error in
extract_insn, at recog.c:2130
Looks like it's generating a 16-bit instruction to move data between
two single-precision floating-point registers?
Please email me to receive the testcase.
