Hello,
I noticed what appears to be a long-standing bug in generating .dwarf_frame
sections with GCC on Linux on PowerPC.
...
So I'm wondering where to go from here
-bit i386, and
some other operating systems on ppc (AIX, Darwin, BSD).
Bye,
Ulrich

So I'm wondering where to go from here. I guess we could:
1. Bring GCC (and gas) behaviour in compliance with the documented ABI
by removing the #undef DBX_REGISTER_NUMBER and changing
the condition code hack: simply use identical
numbers in .eh_frame and .dwarf_frame. This would make PowerPC
like other Linux platforms in that respect.
Thoughts?
Bye,
Ulrich
