            Bug ID: 69488
           Summary: tests in gnat/sso give a lot of incorrect FAIL
                    results, output pattern matching goes wrong on mingw
                    host
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rainer@emrich-ebersheim.de
  Target Milestone: ---

Two examples from about 300 in gnat/sso:

Setting LD_LIBRARY_PATH to
:/opt/devel/SCRATCH/tmp.FDPvU82tbA/gcc-6.0.0/gcc-6.0.0/gcc::/opt/devel/SCRATCH/tmp.FDPvU82tbA/gcc-6.0.0/gcc-6.0.0/gcc:.
spawn [open ...]^M
X_L = (S => 12345, C => 'a')^M
X_H = (S => 23456, C => 'b')^M
X_H = (S => 12345, C => 'a')^M
PASS: gnat.dg/sso/conv1.adb   -Og -g  execution test
FAIL: gnat.dg/sso/conv1.adb   -Og -g  output pattern test
Output was:
X_L = (S => 12345, C => 'a')^M
X_H = (S => 23456, C => 'b')^M
X_H = (S => 12345, C => 'a')^M

Should match:
X_L = \(S => 12345, C => 'a'\)
X_H = \(S => 23456, C => 'b'\)
X_H = \(S => 12345, C => 'a'\)

Here we have an issue with escaping and line endings unix versus dos.

Local_R2 : 12 34 56 78^M
Local_R1 : 78 56 34 12^M
Local_R2 : 12 34 56 78^M

Should match:

My_R2    : 12 34 56 78
Local_R1 : 78 56 34 12

Local_R2 : 12 34 56 78
Local_R1 : 78 56 34 12
Local_R2 : 12 34 56 78

Line endings issue.

Does somebody know how to fix this?
