LGTM.
It's obvious you fixed my previous redundant codes.
Thanks.

Subject: [PATCH 2/2] RISC-V: Refactor vector reduction patterns
This patch adjust reduction patterns struct, change it from:
(any_reduc:VI
(vec_duplicate:VI
(vec_select:<VEL>
(match_operand:<V_LMUL1> 4 "register_operand" " vr,
vr")
(parallel [(const_int 0)])))
(match_operand:VI 3 "register_operand" " vr,
vr"))
to:
(unspec:<V_LMUL1> [
(match_operand:VI 3 "register_operand" " vr,
vr")
(match_operand:<V_LMUL1> 4 "register_operand" " vr,
vr")
] ANY_REDUC)
The reason for the change is that the semantics of the previous pattern is
incorrect.
GCC does not have a standard rtx code to express the reduction calculation
process.
It makes more sense to use UNSPEC.
Further, all reduction icode are geted by the UNSPEC and MODE (code_for_pred
(unspec, mode)),
so that all reduction patterns can have a uniform icode name. After this
adjust, widen_reducop
and widen_freducop are redundant.
gcc/ChangeLog:
* config/riscv/autovec.md: Change rtx code to unspec.
* config/riscv/riscv-protos.h (expand_reduction): Change prototype.
* config/riscv/riscv-v.cc (expand_reduction): Change prototype.
* config/riscv/riscv-vector-builtins-bases.cc (class widen_reducop):
Removed.
(class widen_freducop): Removed.
* config/riscv/vector-iterators.md (minu): Add reduc unspec, iterators, attrs.
* config/riscv/vector.md (@pred_reduc_<reduc><mode>): Change name.
(@pred_<reduc_op><mode>): New name.
(@pred_widen_reduc_plus<v_su><mode>): Change name.
(@pred_reduc_plus<order><mode>): Change name.
(@pred_widen_reduc_plus<order><mode>): Change name.
