[Bug target/32389] New: [4.1/4.2/4.3 Regression] ICE in extract_constrain_insn_cached when using -msse

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

this was noticed while compiling the CAPS audio plugins

gcc-3.4.6 and gcc-4.0.4 work, but gcc-4.1.0 and newer releases fail ... also
tested with current snaps (4.1-20070611, 4.2-20070613, 4.3-20070615)

$ gcc -c -msse test.i -m32
test.i: In function 'f2':
test.i:5: error: insn does not satisfy its constraints:
(insn 35 33 36 (set (reg:SI 1 dx)
        (reg/f:SI 54 virtual-stack-vars)) 40 {*movsi_1} (nil)
    (expr_list:REG_DEAD (reg/f:SI 54 virtual-stack-vars)
        (nil)))
test.i:5: internal compiler error: in extract_constrain_insn_cached, at
recog.c:1994
Please submit a full bug report,
