            Bug ID: 31628
           Summary: [gdb/testsuite] Support different compiler versions
                    for different languages
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: testsuite
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

I recently tried a testsuite run with the clang/clang++ compiler.

I ran into some failures in gdb.ada due to the use of test_compiler_info.

No language argument is specified because ada is not supported, but then the
language defaults to c, meaning the compiler info test is done using clang but
the compiler used is gnatmake.

I disregarded this, because the setup is a bit weird, but today I came across a
machine on the gcc compile farm with gnatmake 10.5.0 and gcc 11.4.0, where I
run into the exact same problem.

A solution could be to drop defaulting to c in test_compiler_info, but it's
used in ~300 locations, so that could prove hard to fix manually.  Another
approach would be to choose the default based on test dir, so ada in gdb.ada
and so on.

Anyway, probably support for ada needs to be added in test_compiler_info
regardless.

--- Comment #1 from Tom de Vries <vries at gcc dot gnu.org> ---
I tried to work around this by using CC_FOR_TARGET etc.

But we have
- gcc-10 and gcc-11
- g++-11
- gfortran-11
- gnatmake-10
so I can't make a set that is consistent.
