As the de facto maintainer of the ppc64 bits of oprofile, I was
recently asked to look into an oprofile bug where it was incorrectly
demangling 64-bit symbols. The oprofile code uses the libiberty
function, cplus_demangle(), but is not getting back the right answer
for ppc64 64-bit symbols. This appears to be more fallout from the
change (made a couple years ago or so) to the opd for ppc64, where the
leading "." was removed from 64-bit symbols.
I hacked around the problem in my private oprofile src tree, but I'm
thinking this issue should be solved at its source. I'm seeing this
problem on a SLES 10 system with binutils version 2.16.91. Has this
possibly been resolved in a more recent binutils version or in CVS?
