--- Comment #7 from Benjamin Kosnik <bkoz at gcc dot gnu.org> 2011-02-24 19:28:02 UTC ---

ack, I mis-read rtti.c, these are the decimal exports, ie decimal128  not
float128.

Jakub you are correct these are exports as LD symbols via ld versioning via
inclusion. I missed that!

%find . -type f | xargs grep _ZTIg

./powerpc64-linux-gnu/32/baseline_symbols.txt:OBJECT:8:_ZTIg@@CXXABI_LDBL_1.3

./alpha-linux-gnu/baseline_symbols.txt:OBJECT:16:_ZTIg@@CXXABI_LDBL_1.3

sparc may be questionable in reality as it is inferred on alpha.
