Hi!
These 3 tests use compiler_version() and/or compiler_options() functions,
which are inherently incompatible with -fcompare-debug compilation, as they
emit into a string literal in the assembly the exact f951 command line
options, which differs between the two compilations with -fcompare-debug,
where one has -gtoggle and -fcompare-debug-second options added and
different -fdump-final-insns= option argument.
The following patch adds dg-skip-if directives, so that these tests are
ignored during
make check-gfortran RUNTESTFLAGS='--target_board=unix/-fcompare-debug'
Tested on x86_64-linux without (where the 3 tests FAIL) and with the patch, ok
for
trunk?
