Subject: aarch64: fix gcc.target/aarch64/pcs_attribute-2.c on non-gnu targets
X-Git-Tag: upstream/12.2.0~23871
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5ed12b58ef022b5186edc6c31eb05addc828fd8b;p=platform%2Fupstream%2Fgcc.git

aarch64: fix gcc.target/aarch64/pcs_attribute-2.c on non-gnu targets

Move the ifunc symbol tests into a separate file with dg-require-ifunc.
And added a base pcs ifunc symbol to the test for completeness.

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/pcs_attribute-2.c: Remove ifunc usage.
	* gcc.target/aarch64/pcs_attribute-3.c: New test.
