[Bug target/18353] New: ICE with "movaps" in inline asm when using -masm=intel

[dannysmith at users dot sourceforge dot net]

Compiling following:

/* movaps.c */
struct v4f { float f[4];} __attribute__ ((aligned (16),packed));

void foo (void)
{
  struct v4f a = {{1.0f, 2.0f, 3.0f, 4.0f}};
  __asm__ __volatile__ ("movaps %0, %%xmm0"::"X"(a));
}

with gcc -c -msse2 -masm=intel movaps.c

gives:

> movaps.c: In function `void foo()':
> movaps.c:7: internal compiler error: in print_operand, at 
config/i386/i386.c:6564

The code compiles without error, using default asm syntax

gcc version 4.0.0 20041101 (experimental)

3.3.3 and 3.4.3 releases also ICE with -masm=intel

I think this is invalid, the operand is wrong, you cannot pass a struct to an operand of an asm, see PR 
8788 for another example of where the problem can come into play.

Confirmed.
