             Bug #: 50076
           Summary: FAIL: c-c++-common/cxxbitfields-3.c scan-assembler
                    movl.*, var on x86_64-apple-darwin10
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite

            Target: x86_64-apple-darwin10
             Build: x86_64-apple-darwin10


scan-assembler for c-c++-common/cxxbitfields-3.c fails on
x86_64-apple-darwin10. The assembly is

    .byte    0
    .align 3

The test has been introduced in revision 176824 and probably never succeeded. I
cannot tell if the test should be updated for darwin or if it is a bug in the
compiler.

Could someone look at this pr and decide if the code

    movq    _var@GOTPCREL(%rip), %rdx
    movl    (%rdx), %eax

is buggy (in this case I cannot help) or if the dg-final has to be adjusted for
darwin (then I can try to find a suitable regexp).

I will be contributing a testing harness that is back-end agnostic, so it won't
depend on scanning the assembly.  Stay tuned.

Any progress in this direction?

A "stronger" fix has been proposed at
http://gcc.gnu.org/ml/gcc-patches/2011-12/msg00895.html and approved at
http://gcc.gnu.org/ml/gcc-patches/2011-12/msg00897.html . Could it be applied?
TIA.

I can confirm that r184140 fixes the c-c++-common/cxxbitfields-3.c failures on
x86_64-apple-darwin11.
