Hi,
A new vendor CFA DW_CFA_AARCH64_negate_ra_state was introduced for
ARMv8.3-A
return address signing, it is multiplexing DW_CFA_GNU_window_save in
CFA vendor
extension space.
This patch adds necessary code to make it available to external, the
GDB
patch (https://sourceware.org/ml/gdb-patches/2017-08/msg00215.html) is
intended
to use it.
A new DW_CFA_DUP for it is added in dwarf2.def. The use of
DW_CFA_DUP is to
avoid duplicated case value issue when included in libiberty/dwarfnames.
Native x86 builds OK to make sure no macro expanding errors.
OK for trunk?
