[PATCH RFA] testsuite changes needed for AIX 4.3
- To: gdb-patches at sourceware dot cygnus dot com
- Subject: [PATCH RFA] testsuite changes needed for AIX 4.3

I hereby reqest approval for committing the following changes:
* gdb.base/pointers.c (usevar): New function.
(main): Make sure that global variables v_int_pointer2, rptr,
and y are all referenced someplace in the program by calling
usevar() on them. [Some linkers delete symbols which are
never referenced. The space remains, but there's no way to
get a (symbolic) handle on the variable from the debugger.]
* gdb.base/scope.exp: For powerpc-*-*, xfail the same tests
that rs6000-*-* does.
