VECT: Support SLP MASK_LEN_GATHER_LOAD with conditional mask
This patch leverage current MASK_GATHER_LOAD to support SLP MASK_LEN_GATHER_LOAD with condtional mask.
Unconditional MASK_LEN_GATHER_LOAD (base, offset, scale, zero, -1) SLP is not included in this patch
since it seems that we can't support it in the middle-end:
FAIL: gcc.dg/tree-ssa/pr44306.c (internal compiler error: in vectorizable_load, at tree-vect-stmts.cc:9885)
May be we should support GATHER_LOAD explictily in RISC-V backend to walk around this issue.
I am gonna support GATHER_LOAD explictly work around in RISC-V backend.
This patch also adds conditional gather load test since there is no conditional gather load test.
Ok for trunk ?
gcc/ChangeLog:
* tree-vect-slp.cc (vect_get_operand_map): Add MASK_LEN_GATHER_LOAD.
(vect_build_slp_tree_1): Ditto.
(vect_build_slp_tree_2): Ditto.
gcc/testsuite/ChangeLog:
* gcc.dg/vect/vect-gather-6.c: New test.
