            Bug ID: 20284
           Summary: GDB failures in gdb trunk
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

The following tests started failing on gdb 7.5 with the patch that enables
-gcolumn-info by default
(http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20140707/109641.html).

         FAIL: gdb.reverse/step-precsave.exp: reverse step out of called fn
         FAIL: gdb.reverse/step-precsave.exp: reverse next over call
         FAIL: gdb.reverse/step-precsave.exp: reverse step test 1
         FAIL: gdb.reverse/step-precsave.exp: reverse next test 1
         FAIL: gdb.reverse/step-precsave.exp: reverse next test 2
         FAIL: gdb.reverse/step-reverse.exp: reverse step out of called fn
         FAIL: gdb.reverse/step-reverse.exp: reverse next over call
         FAIL: gdb.reverse/step-reverse.exp: reverse step test 1
         FAIL: gdb.reverse/step-reverse.exp: reverse next test 1
         FAIL: gdb.reverse/step-reverse.exp: reverse next test 2

I tried running the gdb testsuite from gdb trunk, and these failures reproduce
there with or without my -gcolumn-info patch.  I think that these tests were
working in 7.5 by chance.

I've XFAIL'd them for now in clang-tests-external.
