gcc/
* config/rs6000/rs6000.c (rs6000_function_arg_boundary): In the AIX
and ELFv2 ABI, do not use the "mode == BLKmode" check to test for
aggregate types. Instead, *all* aggregate types, except for single-
element or homogeneous float/vector aggregates, are quadword-aligned
if required by their type alignment. Issue -Wpsabi note when a type
is now treated differently than before.
gcc/testsuite/
* gcc.target/powerpc/ppc64-abi-warn-2.c: New test.
