This adds a get_DW_UT_name function to dwarfnames using dwarf2.def
for use in binutils readelf to show the unit types in a DWARF5 header.
Also remove DW_CIE_VERSION which was already removed in binutils/gdb
and is not used in gcc.
include/ChangeLog:
* dwarf2.def: Add DWARF5 Unit type header encoding macros
DW_UT_FIRST, DW_UT and DW_UT_END.
* dwarf2.h (enum dwarf_unit_type): Removed and define using
DW_UT_FIRST, DW_UT and DW_UT_END macros.
(DW_CIE_VERSION): Removed.
(get_DW_UT_name): New function declaration.
libiberty/ChangeLog:
* dwarfnames.c (get_DW_UT_name): Define using DW_UT_FIRST, DW_UT
and DW_UT_END.
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.
