Bug ID: 110265
Summary: RISC-V: ICE when build RVV intrinsic with
"-march=rv32gc_zve64d -mabi=ilp32d"
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
Target Milestone: ---

Reproduce source code
Given we have the below code.
#include "riscv_vector.h"
vint16m1_t test_vredmax_vs_i16mf4_i16m1(vint16mf4_t vector, vint16m1_t scalar,
size_t vl) {
return __riscv_vredmax_vs_i16mf4_i16m1(vector, scalar, vl);
}
There will be the ICE when build similar as "riscv64-unknown-elf-gcc
-march=rv32gc_zve64d -mabi=ilp32d -O3 -Wno-psabi test-int.c -c -S -o -".
>> ../__RISC-V_INSTALL_/bin/riscv64-unknown-elf-gcc -march=rv32gc_zve64d
>> -mabi=ilp32d -O3 -Wno-psabi test-int.c -c -S -o -
