RISC-V: Support RVV zvfh{min} vfloat16*_t mov and spill
Checks
Commit Message
From: Pan Li <pan2.li@intel.com>
This patch would like to allow the mov and spill operation for the RVV
vfloat16*_t types. The involved machine mode includes VNx1HF, VNx2HF,
VNx4HF, VNx8HF, VNx16HF, VNx32HF and VNx64HF.

gcc/ChangeLog:
* config/riscv/riscv-vector-builtins-types.def
(vfloat16mf4_t): Add the float16 type to DEF_RVV_F_OPS.
(vfloat16mf2_t): Likewise.
(vfloat16m1_t): Likewise.
(vfloat16m2_t): Likewise.
(vfloat16m4_t): Likewise.
(vfloat16m8_t): Likewise.
* config/riscv/riscv.md: Add vfloat16*_t to attr mode.
* config/riscv/vector-iterators.md: Add vfloat16*_t machine mode
to V, V_WHOLE, V_FRACT, VINDEX, VM, VEL and sew.
* config/riscv/vector.md: Add vfloat16*_t machine mode to sew,
vlmul and ratio.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/base/mov-14.c: New test.
* gcc.target/riscv/rvv/base/spill-13.c: New test.

LGTM. Hope FP16 vector can be committed soon.
Since I would like to wait for FP16 vector and then start to support FP16 FP32 FP64 autovec together.
Thanks.

Subject: Re: [PATCH] RISC-V: Support RVV zvfh{min} vfloat16*_t mov and spill
LGTM. Hope FP16 vector can be committed soon.
Since I would like to wait for FP16 vector and then start to support FP16 FP32 FP64 autovec together.
Thanks.

Subject: [PATCH] RISC-V: Support RVV zvfh{min} vfloat16*_t mov and spill
From: Pan Li <pan2.li@intel.com<mailto:pan2.li@intel.com>>
This patch would like to allow the mov and spill operation for the RVV
vfloat16*_t types. The involved machine mode includes VNx1HF, VNx2HF,
VNx4HF, VNx8HF, VNx16HF, VNx32HF and VNx64HF.

gcc/ChangeLog:
* config/riscv/riscv-vector-builtins-types.def
(vfloat16mf4_t): Add the float16 type to DEF_RVV_F_OPS.
(vfloat16mf2_t): Likewise.
(vfloat16m1_t): Likewise.
(vfloat16m2_t): Likewise.
(vfloat16m4_t): Likewise.
(vfloat16m8_t): Likewise.
* config/riscv/riscv.md: Add vfloat16*_t to attr mode.
* config/riscv/vector-iterators.md: Add vfloat16*_t machine mode
to V, V_WHOLE, V_FRACT, VINDEX, VM, VEL and sew.
* config/riscv/vector.md: Add vfloat16*_t machine mode to sew,
vlmul and ratio.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/base/mov-14.c: New test.
* gcc.target/riscv/rvv/base/spill-13.c: New test.

Subject: Re: [PATCH] RISC-V: Support RVV zvfh{min} vfloat16*_t mov and spill
LGTM. Hope FP16 vector can be committed soon.
Since I would like to wait for FP16 vector and then start to support FP16 FP32 FP64 autovec together.
Thanks.

Subject: [PATCH] RISC-V: Support RVV zvfh{min} vfloat16*_t mov and spill
From: Pan Li <pan2.li@intel.com<mailto:pan2.li@intel.com><mailto:pan2.li@intel.com<mailto:pan2.li@intel.com>>>
This patch would like to allow the mov and spill operation for the RVV
vfloat16*_t types. The involved machine mode includes VNx1HF, VNx2HF,
VNx4HF, VNx8HF, VNx16HF, VNx32HF and VNx64HF.

gcc/ChangeLog:
* config/riscv/riscv-vector-builtins-types.def
(vfloat16mf4_t): Add the float16 type to DEF_RVV_F_OPS.
(vfloat16mf2_t): Likewise.
(vfloat16m1_t): Likewise.
(vfloat16m2_t): Likewise.
(vfloat16m4_t): Likewise.
(vfloat16m8_t): Likewise.
* config/riscv/riscv.md: Add vfloat16*_t to attr mode.
* config/riscv/vector-iterators.md: Add vfloat16*_t machine mode
to V, V_WHOLE, V_FRACT, VINDEX, VM, VEL and sew.
* config/riscv/vector.md: Add vfloat16*_t machine mode to sew,
vlmul and ratio.
gcc/testsuite/ChangeLog:
