From: Pan Li <pan2...@intel.com>
This patch would like to support the rounding mode API for the
VFWCVT.X.F.V as the below samples.
* __riscv_vfwcvt_xu_f_v_u64m2_rm
* __riscv_vfwcvt_xu_f_v_u64m2_rm_m
Signed-off-by: Pan Li <pan2...@intel.com>
gcc/ChangeLog:
* config/riscv/riscv-vector-builtins-bases.cc
(vfwcvt_xu_frm_obj): New declaration.
(BASE): Ditto.
* config/riscv/riscv-vector-builtins-bases.h: Ditto.
* config/riscv/riscv-vector-builtins-functions.def
(vfwcvt_xu_frm): New intrinsic function definition.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/base/float-point-wcvt-xu.c: New test.
