Subject: pointer-compare-1.c: Add __attribute__((used))
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9dbf8dc7a96a8020e0ee05926ef7a3f976e9c318;p=gcc.git

pointer-compare-1.c: Add __attribute__((used))

c-c++-common/asan/pointer-compare-1.c assumes the certain order for
variable placement.  Add __attribute__((used)) to avoid variable
placement changes due to SHF_GNU_RETAIN.

	PR testsuite/97803
	* c-c++-common/asan/pointer-compare-1.c (global1): Add
	__attribute__((used))
	(global2): Likewise.
	(small_global): Likewise.
	(large_global): Likewise.
