           Summary: ICE in reload_cse_simplify_operands, at
                    postreload.c:403
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ams@gcc.gnu.org


Created attachment 23755
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23755
Reduced testcase.

Using a trunk (svn 171251) compiler, configured for ARMv7-a, I get the
following ICE:

gcc -marm -mfpu=neon -O2 -c lp723185.i 

lp723185.i: In function 'foo':
lp723185.i:29:1: error: insn does not satisfy its constraints:
(insn 30 79 31 5 (set (mem/s:DI (plus:SI (reg:SI 3 r3)
                (const_int -3 [0xfffffffffffffffd])) [4 unaligned_S_6->u64+0 S8
A64])
        (reg:DI 4 r4 [146])) lp723185.i:25 626 {*arm_movdi_vfp}
     (nil))
lp723185.i:29:1: internal compiler error: in reload_cse_simplify_operands, at
postreload.c:403
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.


It's possible that this is the same as bug #42949, but I'm not qualified to
judge.

Confirmed on trunk, r171212.

Works on latest 4.5 (r171282).

I don't think this is the same bug as PR42949 because that one has now ceased
to occur - for me at least.

Fixed on trunk . 

Needs backporting to 4.6 branch.

A backport to 4.6 shows the following failures -

-fomit-frame-pointer -funroll-all-loops -finline-functions  (internal compiler
error)

I was not able to reproduce these ICEs, tried backporting to both mainline
gcc-4_6-branch and a latest Linaro 4.6 pull.
