Subject: [PATCH 2/3] Sync libiberty and include with GCC for get_DW_UT_name.
Date: Wed, 23 Sep 2020 16:51:51 +0200 [thread overview]
Message-ID: <20200923145152.27111-2-mark@klomp.org> (raw)
In-Reply-To: <20200923145152.27111-1-mark@klomp.org>
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.
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.
(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.
