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. Committed on behalf of Jiong Wang. include/ * dwarf2.def (DW_CFA_AARCH64_negate_ra_state): New DW_CFA_DUP. * dwarf2.h (DW_CFA_DUP): New define. libiberty/ * dwarfnames.c (DW_CFA_DUP): New define.
