X-Git-Tag: basepoints/gcc-15~7470

RISC-V: Fix one incorrect match operand for RVV reduction

There are 2 of the RVV reduction pattern mask operand takes
vector_merge_operand instead of vector_mask_operand by mistake. This
patch would like to fix this.

Signed-off-by: Pan Li <pan2.li@intel.com>

gcc/ChangeLog:

	* config/riscv/vector.md: Fix incorrect match_operand.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/base/pr110299-1.c: Adjust tests.
	* gcc.target/riscv/rvv/base/pr110299-2.c: Ditto.
