* [Bug target/27829] New: ICE/abort in shift_op, at config/arm/arm.c:7917 with asm from testsuite/gcc.dg/pr21255-2-mb.c

Calling an ARM-targeted GCC 3.4.4 on the testsuite file gcc.dg/pr21255-2-mb.c
results in "internal compiler error: in shift_op, at config/arm/arm.c:7917".
A slightly reduced version of the file is:
double d;
double
f (void)
{
double r;
asm ("mov %S1,%S0; mov %R1,%R0" : "=&r" (r) : "m" (d));
return r;
}
The relevant source seems to be:
if (GET_CODE (XEXP (op, 1)) == REG || GET_CODE (XEXP (op, 1)) == SUBREG)
*amountp = -1;
else if (GET_CODE (XEXP (op, 1)) == CONST_INT)
*amountp = INTVAL (XEXP (op, 1));
else
abort ();
CodeSourcery versions 3.4.4 (release) (CodeSourcery ARM 2005q3-2) and
2006q1/4.1.0 give a similar error.
x86 GCC 3.3.5 (Debian 1:3.3.5-8ubuntu2), and a checking=all build of 4.1.0
instead give an apparently reasonable rejection message: "error: invalid `asm':
invalid operand code `R'".
================
Here's the session; I'll attach the preprocessed source.

Does this happen in 3.4.5 or 3.4.6?
Also 3.4.x is no longer being maintainer, does this happen in 4.0.x or 4.1.x?

It does happen in CodeSourcery's version of 4.1.0 (which I've filed noted above
and with them). I don't have access to an ARM-targeted 3.4.5, 3.4.6, 4.0.x,
nor a non-CodeSourcery 4.1.x.
