Subject: Fix implementation of readelf's -wE and -wN options,
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=aa40d66bb18c7aa068179f42de52327a0711834e;p=binutils-gdb.git

Fix implementation of readelf's -wE and -wN options,

	* dwarf.c (dwarf_select_sections_by_name): If the entry's value is
	zero then clear the corresponding variable.
	(dwarf_select_sections_by_letters): Likewise.
	* testsuite/binutils-all/debuginfo.exp: Expect -WE and -wE
	debuginfod tests to fail.
---
