[PATCH] testsuite, rs6000: Adjust ppc-fortran.exp to support dg-{warning,error}

[PATCH] testsuite, rs6000: Adjust ppc-fortran.exp to support dg-{warning,error}

[Kewen.Lin]

Hi,

According to Haochen's finding in [1], currently ppc-fortran.exp
doesn't support Fortran specific warning or error messages well.
By looking into it, it's due to that gfortran uses some different
warning/error prefixes as follows:

    set gcc_warning_prefix "\[Ww\]arning:"
    set gcc_error_prefix "(Fatal )?\[Ee\]rror:"

comparing to:

    set gcc_warning_prefix "warning:"
    set gcc_error_prefix "(fatal )?error:"

So this is to override these two prefixes and make it support
dg-{warning,error} checks.

Tested on powerpc64-linux-gnu P7/P8/P9 and
powerpc64le-linux-gnu P9/P10.

Hi Kewen,
  I tested it with my fortran test case. It works. Thanks a lot.
