--- Comment #16 from Iain Sandoe <iains at gcc dot gnu.org> 2011-06-26 17:37:00 UTC ---
This bug has been around since part way through 4.5.
Unfortunately, it is somewhat hidden in the test-suite since the latter
interposes the newly-built libgcc ahead of the system version (because
DYLD_LIBRARY_PATH is set to point to ./gcc, of necessity).
There are two steps needed to deal with this fully:
(a) fix things so we don't emit epilogue info in unwind frames for darwin 8,9
and 10 (compacter).
The patch currently attached is OK on 4.6.x - but the emitting of unwind frames
has been recently vec-ified which means it will need some re-work for trunk.
(b) fix the darwin libgcc build process so that we only export the _ext symbols
from newly-built libgcc when this is only supporting the ext.
* (b) will also solve the library ordering issues when -{force}_flat_namespace
is used.
I have another patch in progress that is a first attempt at (b) - (not yet
ready to post).
