Question about naming of overloaded policy load functions

[kuanlinchentw]

Hi,
Why _mu series load intrinsics cannot be overloaded without type in the function name?

In vector_loads_and_stores_functions, __riscv_vle16_v_f16mf4_mu, __riscv_vle16_v_f16mf2_mu, etc., are with type in the function name.
But __riscv_vle16_tumu,__riscv_vle16_tum, etc., are without types in the function name.

Thanks.

Thank you for posting this, I think you have found a miss in the specification (and the generated unit tests). I have just checked the latest upstream LLVM compiler and it is able to compile the following.

vfloat16mf2_t test_vle16_mu(vbool32_t mask, vfloat16mf2_t maskedoff, const _Float16 *base, size_t vl) {
  return __riscv_vle16_mu(mask, maskedoff, base, vl);
}

I will submit a patch to fix this. Thanks again for checking.

Seem like GCC has honor the spec...:P

BTW, __riscv_viota_m_u8mf8_mu is the same.

Yeah, GCC has strictly followed SPEC:

bool can_be_overloaded_p (enum predication_type_index pred) const override
{
if (STORE_P || LST_TYPE == LST_INDEXED)
return true;
return pred != PRED_TYPE_none && pred != PRED_TYPE_mu;
}

....

It seems that I need to remove pred != PRED_TYPE_mu;
