             Bug #: 51876
           Summary: [4.7 regression] Recent extra neon related testsuite
                    regressions on arm-linux-gnueabi
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ramana@gcc.gnu.org


A noticed a few of the neon tests are failing for arm-linux-gnueabi started
failing recently. Skimming through some results on gcc-testresults I see that 
http://gcc.gnu.org/ml/gcc-testresults/2012-01/msg01284.html have these failures 
while this set of results
http://gcc.gnu.org/ml/gcc-testresults/2012-01/msg00370.html that these tests
were passing. Therefore this is a recent regression.

A git bisect shows this to be in the range of 183050 - 183052 , 

Richard : can you take a look ?

Created attachment 26349
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26349
gcc47-pr51876.patch

Untested fix (well, tested that the ICEs are gone on all these tests with a
cross).  vswp just seems to swap two vector registers, so it doesn't matter
which one is the first and which is the second, and the pattern only has two
operands, not 3.
Ramana, could you please bootstrap/regtest it on some real hw?

Doesn't matter which order you do the vswp it's just a swap of 2 vector
registers. 

Looks obvious to me.

I'd take that as an approval.

I did, but I'm waiting for testing results from Ramana.
