From: Pan Li <pan2...@intel.com>
This patch would like to add FP16 support for the VRGATHEREI16
intrinsic. Aka:
* __riscv_vrgatherei16_vv_f16mf4
* __riscv_vrgatherei16_vv_f16mf4_m
As well as f16mf2 to f16m8 types.
Signed-off-by: Pan Li <pan2...@intel.com>
gcc/ChangeLog:
* config/riscv/riscv-vector-builtins-types.def
(vfloat16mf4_t): Add FP16 intrinsic def.
(vfloat16mf2_t): Ditto.
(vfloat16m1_t): Ditto.
(vfloat16m2_t): Ditto.
(vfloat16m4_t): Ditto.
(vfloat16m8_t): Ditto.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/intrisinc-vrgatherei16.c: New test.
