Hello,
in testing the rs6000 ABI patches I noted a weird effect: usually, the
-Wpsabi warning notes are ignored in the compat test suites, so we get
a clean test run anyway.
However, when running the C++ version of the struct-layout-1.exp case
*alone* (using RUNTESTFLAGS=struct-layout-1.exp), suddenly tests are
failing because of those extra notes. This does *not* happen with
the C version of that suite ...
It turns out that that pruning those notes is supposed to happen
from within gcc-defs.exp:${tool}_check_compile:
if { [info proc ${tool}-dg-prune] != "" } {
global target_triplet
set gcc_output [${tool}-dg-prune $target_triplet $gcc_output]
}
However, the g++-dg-prune routine is defined in g++-dg.exp, which
is never included from g++.dg/compat/struct-layout-1.exp (directly
or indirectly). Now, when running the full suite, that file would
have been loaded by some earlier g++.dg .exp file, so everything
works out. But when running struct-layout-1.exp stand-alone, the
g++-dg-prune routine is never defined and thus silently no pruning
takes place.
To fix this, the following patch simply loads g++-dg.exp directly
from g++.dg/compat/struct-layout-1.exp.
Tested on powerpc64-linux and powerpc64le-linux.
OK for mainline (and 4.8/4.9 once the rs6000 ABI patches are
backported there)?
Bye,
Ulrich

Mike,
On a related note:
https://gcc.gnu.org/ml/fortran/2012-03/msg00094.html
The libdirs was applied to dejagnu some time ago, so once we can require
that version (anytime now) we could apply the patch referenced above.
Also see BUG: in the URL above for another missing load_lib.
Thanks,
