The following adds a simple cobol.dg test harness, based on gfortran.dg.
It's invoked by make check-cobol, has a single test that should pass.
Running /home/rguenther/src/gcc/gcc/testsuite/cobol.dg/dg.exp ...
FAIL: cobol.dg/pass.cob -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops
-ftracer -finline-functions (test for excess errors)
=== cobol Summary ===
# of expected passes 10
# of unexpected failures 1
# of unresolved testcases 1
OK?
Thanks,
Richard.
