Re: divmod , division+modulo problem in rtl

Hi and thanks a lot.
I did not get any better things after having change
those few lines.
Anyway ok I just leave it now for catching div and mod
the same time..

But the problem I got here right now is the matching
of a divmodqi4 describe in a define_expand:

My word are define as being 16 bits long same as for
my char whereas my int are 32 bits long.

when I do 
char a,b,c;
c=a/b

I can't make gcc understand I need divmodqi4 and not
divmodhi4..

Gcc is always passing throw divmodhi4 and never in
divmodqi4...

I'm really disappointed think I may have missed
something cause lots of different proc implements
divmodqi4 especially avr one which as approximately
the same definition as me for the words , char and int
except it's twice less...

In my configuration divmodqi4 dosn't look as it can be
match once...
