Hi,
I've included a set of patches in order to demangle return addresses in
aarch64 platforms with pointer authentication.
Besides adding the implementation of the negate_ra_state opcode, there
is a new function in the libdwfl.h header to feed the PAC masks to the
library.
Let me know if there are any concerns with the current version.
Thanks,
German
