            Bug ID: 110299
           Summary: RISC-V: ICE when build RVV intrinsic widen with
                    "-march=rv32gc_zve64d -mabi=ilp32d", both GCC 14 and
                    13.
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pan2.li at intel dot com

Reproduce code

Given we have the below code.

#include "riscv_vector.h"

#include "riscv_vector.h"

vfloat32m1_t test_vfwredosum_vs_f16m1_f32m1(vfloat16m1_t vector, vfloat32m1_t
scalar, size_t vl) {
  return __riscv_vfwredosum_vs_f16m1_f32m1(vector, scalar, vl);
}

There will be the ICE when build similar as "riscv64-unknown-elf-gcc
-march=rv64gc_zve64d -mabi=lp64 -O3 -Wno-psabi -c -S test-float.c -o -".
