RISC-V: Expand fixed-vlmax/vls vector permutation in targethook
When debugging FAIL: gcc.dg/pr92301.c execution test.
Realize a vls vector permutation situation failed to vectorize since early return false:
- /* For constant size indices, we dont't need to handle it here.
- Just leave it to vec_perm<mode>. */
- if (d->perm.length ().is_constant ())
- return false;
To avoid more potential failed vectorization case. Now expand it in targethook.
gcc/ChangeLog:
* config/riscv/riscv-v.cc (shuffle_generic_patterns): Expand
fixed-vlmax/vls vector permutation.
