Hi,
During 8.x, the rs6000 target-specific mangling was reorganised which uncovered
a long-standing bug in Darwin’s mangling for ‘IBM’ long double. Now the symbols
are correctly mangled, and we end up with a bunch of test link fails.
This patch adds the necessary subset of the Linux long double exports to
Darwin’s
export table.
I have tested this on a few bootstrap/regtest cycles on powerpc-darwin9, and on
the
power7 linux system.
For the record, I’ve noted the library versions from the Linux side, although
Darwin
does not version symbols in this way.
OK for trunk and 8.x?
thanks
Iain
