Subject: Re: Dividing fixed point number by zero returns zero.
Excuse me, what's the reason for marking this bug as invalid? That an
exception on division by zero isn't required?

On PowerPC, one needs to emit arithmetic instructions using the mnemonic with
the "o" suffix to test for overflow (including divide by zero). The GCC
language and/or front-end would need to inform the backend

The behaviour with -gnato and without is the same. On the other hand, 'digits
18' fails as shown,'digits
9' gives the exception ...
and 'Machine_Overflows is True.

Could you try to add before "end g;" the following line:
Ada.Text_IO.Put_Line (Boolean'Image (T'Machine_Overflows));
And report wether it prints True or False? On x86 and x86_64-linux it prints
True but I do

This is a true front-end bug as on PPC divide by zero (in an instruction) does
not raise an exception so
there needs to be an extra check which should have been added by the front-end.
Confirmed on the ma

Does Ada require divide by zero throw an exception or is it just undefined?
