           Summary: [4.4/4.6 Regression] unrecognized insn storing fp
                    (simd) reg in SImode to stack
           Product: gcc
           Version: 4.4.5
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hp@gcc.gnu.org
            Target: sparc64-unknown-linux-gnu


Created attachment 24148
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24148
preprocessed trivially reduced test-case

Most likely also 4.5 and "4.7" but I don't have a corresponding build tree
handy.
Flagged as a regression because 4.3.5 builds it.

Anyway, observe the following ICE with the attachment compiled with "cc1
-fpreprocessed -mptr64 -mstack-bias -mlong-double-128 -m64 -mcpu=ultrasparc
-mvis -O2 -o rc_stat.s rcs5.i" (for 4.4.5):
