Subject: arm: testsuite: fix vgetq_lane tests for c++
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e901cc8f287256ce87151420e3ae17d62acf9189;p=thirdparty%2Fgcc.git

arm: testsuite: fix vgetq_lane tests for c++

Surpringly these tests were lacking the extern "C" that other MVE
intrinsics have, making them fail when tested in C++ mode.

While fixing that:
- remove useless dg-skip-if
- remove hardcoded -mfloat-abi=hard from s64 and u64 versions
- add check-function-bodies to s64 and u64 versions, such that these
  tests no longer appear as duplicates.

gcc/testsuite/ChangeLog:
	* gcc.target/arm/mve/intrinsics/vgetq_lane_f16.c: Add missing
	extern "C". Remove dg-skip-if.
	* gcc.target/arm/mve/intrinsics/vgetq_lane_f32.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vgetq_lane_s16.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vgetq_lane_s32.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vgetq_lane_s8.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vgetq_lane_u16.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vgetq_lane_u32.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vgetq_lane_u8.c: Likewise.
	* gcc.target/arm/mve/intrinsics/vgetq_lane_s64.c: Likewise. Add
	check-function-bodies.
	* gcc.target/arm/mve/intrinsics/vgetq_lane_u64.c: Likewise.
