gdb.dwarf2 test directory

gdb.dwarf2 test directory

[Andrew Cagney]

Hello,

As a sibling to gdb.stabs, should be a gdb.dwarf2 directory?  This would 
let us directly generate and test specific dwarf2 constructs without 
having to rely on a user running a specific version of GCC.

thoughts,
Andrew

Sounds good to me.

I haven't been in gdb.stabs for a while but it's full of strange stuff, 
like 'sed' scripts that run on the host machine (not the build machine).
I don't want that weird stuff copied blindly into gdb.dwarf2.

gdb.dwarf2 is a fine name.

Most of the test suite, even gdb.asm, accepts "runtest --target_board
unix/gdb:debug_flags=-gdwarf-2" or "...=-gstabs+" to specify the debug
format.  Think about how that interacts with an explicit dwarf-2
directory.  Off the top of my head, I think it would be fine to say: "if
the debug_flags includes -gstabs\[+\], then just skip these tests".
We've been stumbling through this issue with asm-source.exp.

Yes.  That's the right way to test!
