--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-03-10 16:40:45 UTC ---
The ABI files look correct to me, powerpc-linux-gnu/baseline_symbols.txt
(== powerpc64-linux-gnu/32/baseline_symbols.txt ) are -m32 files, _M_next_bkt
takes std::size_t argument and the baseline_symbols.txt files for that use j
letter (i.e. unsigned int), while for 64-bit
powerpc64-linux-gnu/baseline_symbols.txt _M_next_bkt uses m letter (i.e.
unsigned long).

find config/abi/post/powerpc* -name \*.txt | xargs grep _M_next_bkt
config/abi/post/powerpc64-linux-gnu/baseline_symbols.txt:FUNC:_ZNKSt8__detail20_Prime_rehash_policy11_M_next_bktEm@@GLIBCXX_3.4.18
config/abi/post/powerpc64-linux-gnu/32/baseline_symbols.txt:FUNC:_ZNKSt8__detail20_Prime_rehash_policy11_M_next_bktEj@@GLIBCXX_3.4.18
config/abi/post/powerpc-linux-gnu/baseline_symbols.txt:FUNC:_ZNKSt8__detail20_Prime_rehash_policy11_M_next_bktEj@@GLIBCXX_3.4.18

If you are building powerpc64-linux --with-cpu=default32, you need to shuffle
the baseline_symbols.txt around (64-bit move into 64/ subdirectory, 32/
subdirectory contents up), but that is not in any way a regression, and if you
haven't done this shuffle you'd get hundreds of other failures, not just these.

A patch that swapped the 32/64 baseline symbols wasn't correctly carried
forward.  After fixing that only the two undesignated symbols remain.

Nevertheless the abi check should really be fixed to make the shuffling
unnecessary.
