Bug ID: 27256
Summary: lldb doesn't support powerpc64 ELFv1 function
Component: All Bugs
Assignee: lldb-dev at lists.llvm.org

LLDB is nearly complete for powerpc, but powerpc64 support needs function
descriptors to get proper symbol tracking. PowerPC64 doesn't use normal
function pointers in ELFv1 (big-endian, little endian now uses ELFv2, which
does use normal function pointers), but instead uses function descriptors.
LLDB can't quite parse this correctly, so disassembly doesn't work quite right.
This is one of the last pieces needed for supporting powerpc64.
