Series [v2] Bug 28191 - Interpret DWARF 5 addrx locations | expand

Commit Message

Giuliano Procida Aug. 27, 2021, 6:57 p.m. UTC
The DWARF 5 location operation DW_OP_addrx is emitted by Clang. It's
not currently understood by libabigail, resulting in symbols not being
linked to their type information in the ABI representation.

This patch adds basic support, using the libdw dwarf_getlocation_attr
function.

Even with this patch, 32-bit DWARF will be misread until elfutils
includes the https://sourceware.org/bugzilla/show_bug.cgi?id=28220
fix.

	* src/abg-dwarf-reader.cc (die_location_address): Use
	dwarf_attr_integrate, dwarf_getlocation and
	dwarf_getlocation_attr to decode addreses, instead of
	die_location_expr and eval_last_constant_dwarf_sub_expr.
	* tests/data/test-read-dwarf/PR25042-libgdbm-clang-dwarf5.so.6.0.0.abi:
	Refresh test reference output; two more symbols have types.
