--- Comment #28 from Kito Cheng <kito at gcc dot gnu.org> ---
pr90883.C got fail for following target:

            | fail reason
arm-eabi    | "Deleted redundant store:" appear dse2
mips-elf    | "Deleted dead store: <retval>.a[*] = 0;" appear at dse2
mips64-elf  | "Deleted dead store: <retval>.a[*] = 0;" appear at dse2
nds32le-elf | "Deleted redundant store:" appear dse2
riscv32-elf | "Deleted redundant store:" appear dse2


And configure options:

            | configure option
arm-eabi    | --target=arm-eabi
mips-elf    | --target=mips-elf
mips64-elf  | --target=mips64-elf
nds32le-elf | --target=nds32le-elf
riscv32-elf | --target=riscv32-elf --with-arch=rv32gc --with-abi=ilp32d
