From: Yunze Zhu <yunze...@linux.alibaba.com>
This commit add support for xtheadvector-specific indexed segment load/store
intrinsics with b/h/w suffix. We also defined enum to be used in
thead-vector.md
https://github.com/XUANTIE-RV/thead-extension-spec/pull/66
V2:
Change to reuse existed thead function base th_loadstore_width.
gcc/ChangeLog:
* config/riscv/riscv-vector-builtins-bases.cc (BASE): New base_name.
* config/riscv/riscv-vector-builtins-bases.h: New function_base.
* config/riscv/riscv-vector-builtins-shapes.cc (build): Define new
builtin shapes.
* config/riscv/riscv-vector-builtins.cc: New rvv_op_info.
* config/riscv/thead-vector-builtins-functions.def (vlxsegb): New
intrinsics def.
(vlxsegh): Ditto.
(vlxsegw): Ditto.
(vlxsegbu): Ditto.
(vlxseghu): Ditto.
(vlxsegwu): Ditto.
(vsxsegb): Ditto.
(vsxsegh): Ditto.
(vsxsegw): Ditto.
* config/riscv/thead-vector.md
(@pred_th_indexed_load<vlmem_op_attr><VT:mode><VI:mode>): New RTL mode.
(@pred_th_indexed_store<vlmem_op_attr><VT:mode><VI:mode>): Ditto.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/xtheadvector/vlxseg-vsxseg.c: New test.
* gcc.target/riscv/rvv/xtheadvector/vlxsegu-vsxseg.c: New test.
