src/sys/lib/libunwind: DwarfParser.hpp
Log Message:
The return address register entry is the DWARF register. On PowerPC,
this is not the same as the internal encoding, since the Link Register
is deliberately non-continous from the other general purpose register
values. To handle this, always translate the value into the internal
format.
