Subject: RISC-V: Add test for vec_duplicate + vsub.vv combine case 1 with GR2VR cost 0
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=621cb3dc9996a160e3e65bce4a8e61da26caafa7;p=thirdparty%2Fgcc.git

RISC-V: Add test for vec_duplicate + vsub.vv combine case 1 with GR2VR cost 0

Add asm dump check test for vec_duplicate + vsub.vv combine to vsub.vx.

The below test suites are passed for this patch.
* The rv64gcv fully regression test.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/autovec/vx_vf/vx-4-i16.c: Add test cases
	for vsub vx combine case 1 with GR2VR cost 0.
	* gcc.target/riscv/rvv/autovec/vx_vf/vx-4-i32.c: Ditto.
	* gcc.target/riscv/rvv/autovec/vx_vf/vx-4-i64.c: Ditto.
	* gcc.target/riscv/rvv/autovec/vx_vf/vx-4-i8.c: Ditto.
	* gcc.target/riscv/rvv/autovec/vx_vf/vx-4-u16.c: Ditto.
	* gcc.target/riscv/rvv/autovec/vx_vf/vx-4-u32.c: Ditto.
	* gcc.target/riscv/rvv/autovec/vx_vf/vx-4-u64.c: Ditto.
	* gcc.target/riscv/rvv/autovec/vx_vf/vx-4-u8.c: Ditto.
