Does LLVM-RL78 use the hardware multiplication/division peripheral unit of RL78/G13 or not?

Hello support team,

I have an impression after reading the following documents that LLVM-RL78 always uses the unit. But the following code doesn’t use it. (I don’t want to use it.) Does LLVM-RL78 use it?

LLVM-RL78-install-folder/user_manual.pdf
LLVM-RL78-install-folder/release_notes.pdf

unsigned short x, y;
unsigned long z;

int main(void)
{
z = x * y;

while(1) ;
}

And I have one more question. The latter document tells us that there are no option to enable/disable the usage of the unit. But e2 studio 2021-04 has the selection check box for use or not use “-mdisable-mda” option at CPU setting property sheet in LLVM-RL78 compiler setting property sheet. Is e2 studio right?

Best regards,
