             Bug #: 52665
           Summary: scan-assembler output produces wrong FAIL due to
                    matching .ident
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: aldot@gcc.gnu.org


I see this regression:
FAIL: gcc.target/i386/pr28946.c scan-assembler-not test

The culprit is the testsuite errnoeously matching my local branch name in the
assembler output's .ident.

$ grep scan ../../src/gcc-4.8/gcc/testsuite/gcc.target/i386/pr28946.c
/* { dg-final { scan-assembler-not "test" } } */

$ ./gcc/xgcc -B/scratch/obj.x86_64/gcc-4.8/gcc/
../../src/gcc-4.8/gcc/testsuite/gcc.target/i386/pr28946.c   -Os
-ffat-lto-objects -S  -o - | grep test
    .ident    "GCC: (GNU) 4.8.0 20120320 (experimental) [fixups-testsuite
revision 1dc2c94:40d1377:d28ff051e43bdf8f8aab692fbf6932a7211ca49d]"

Perhaps output for scan-assembler should be built with -fno-ident ?
