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

["vapier at gentoo dot org" <gcc-bugzilla at gcc dot gnu 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
