Subject: C++ demangling of 64-bit symbols on ppc64
Date: Tue, 03 Apr 2007 22:19:00 -0000	[thread overview]
Message-ID: <4612D2FA.4050407@us.ibm.com> (raw)

Hi all,
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?

Thanks.
-Maynard
