[Bug target/31344] [4.3 regression] Bootstrap failure to compile decLibrary.c

[hjl at lucon dot org]

------- Comment #7 from hjl at lucon dot org  2007-03-26 03:15 -------
It looks like expr.c and i386.c don't agree how to generate push
instuction. i386.c has gen_push and expr.c has emit_single_push_insn.
If emit_single_push_insn is called, it will generate invalid patten:

(insn 10 9 11 3 (set (reg/f:SI 64)
        (pre_dec:SI (reg/f:SI 7 sp))) -1 (nil)
    (nil))

from emit_single_push_insn in expr.c

3519      if (GET_MODE_SIZE (mode) == rounded_size)
3520        dest_addr = gen_rtx_fmt_e (STACK_PUSH_CODE, Pmode,
stack_pointer_rtx);
