[Bug target/29339] New: TImode ICE with -m32 -msse -mtune=i386

["jsm28 at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Compile the following (derived from gcc.dg/format/unnamed-1.c) on
x86_64-unknown-linux-gnu with -m32 -msse -mtune=i386.

extern void g (const char *, ...);

void
f (void)
{
  g ("", 0xffffffffffffffffffffffffffffffff);
}

You get an ICE (with both mainline as of 20061003 and older compilers):

u.c:6:10: warning: integer constant is too large for its type
u.c: In function 'f':
u.c:6: warning: integer constant is too large for 'long' type
u.c:7: error: unrecognizable insn:
(insn 8 7 9 3 (set (mem/i:TI (pre_dec:SI (reg/f:SI 7 sp)) [0 S16 A128])
        (reg:TI 58)) -1 (nil)
    (nil))
u.c:7: internal compiler error: in extract_insn, at recog.c:2077
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

(The choice of x86_64 -m32 is because this ICE requires 64-bit HOST_WIDE_INT;
32-bit i?86 configurations that use 64-bit HOST_WIDE_INT should show this as
well.)
