[Bug target/28132] New: [4.1 Regression] ICE instantiate_virtual_regs_in_insn when -fforce-addr -O1 used

[vapier at gentoo dot org]

building spidermonkey-1.5 with -O1 -fforce-addr with gcc-4.1.1 and gcc ICEs:
jsmath.c: In function 'math_round':
jsmath.c:394: error: unrecognizable insn:
(insn 61 93 62 4 (parallel [
            (set (mem/i:DF (reg/f:SI 95) [0 S8 A32])
                (neg:DF (mem/i:DF (reg/f:SI 96) [0 S8 A32])))
            (use (const_int 0 [0x0]))
            (clobber (reg:CC 17 flags))
        ]) -1 (nil)
    (nil))
jsmath.c:394: internal compiler error: in instantiate_virtual_regs_in_insn, at
function.c:1555

this sort of looks like PR23196, but that is fixed in my 4.1.1

verified on Gentoo and Debian

------- Comment #2 from rguenth at gcc dot gnu dot org  2006-06-22 09:26 -------
Confirmed.  Requires -O -fforce-addr -march=i686.

void math_round()
{
        double x;
        foo(x, __builtin_copysign(bar(), x));
}

works on the mainline.

A regression hunt using the testcase and options from comment #2 with an
i686-linux cross compiler identified the following patch which fixed the bug on
mainline:

P2, rather than P1, due to use of relatively obscure command-line option.

Closing 4.1 branch.  Not updating known-to-fail since logs suggest it might in
fact be fixed there.
