Subject: Fix gdb.base/list.exp with Clang
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=308975919152fbf301861d88e2da9b522e3cf112;p=binutils-gdb.git

Fix gdb.base/list.exp with Clang

Two subtests of gdb.base/list.exp failed when built with Clang
because the unused function "unused" was optimized out.  This
commit adds __attribute__ ((used)) to both definitions.

gdb/testsuite/ChangeLog:

	* gdb.base/list0.c (unused): Add __attribute__ ((used)).
	* gdb.base/list1.c (unused): Likewise.
