LoongArch: Adjust cost of vector_stmt that match multiply-add pattern.
We found that when only 128-bit vectorization was enabled, 549.fotonik3d_r
failed to vectorize effectively. For this reason, we adjust the cost of
128-bit vector_stmt that match the multiply-add pattern to facilitate 128-bit
vectorization.
The experimental results show that after the modification, 549.fotonik3d_r
performance can be improved by 9.77% under the 128-bit vectorization option.
gcc/ChangeLog:
* config/loongarch/loongarch.cc (loongarch_multiply_add_p): New.
(loongarch_vector_costs::add_stmt_cost): Adjust.
gcc/testsuite/ChangeLog:
* gfortran.dg/vect/vect-10.f90: New test.
