[Mspgcc-users] A lot of questions.

[Mauricio Scaff]

Hi,
I have a lot of questions :

1) How do I know what have changed between 2 mspgcc releases ? Is there some 
ChangeLog file ?

2) Is there some way to know the maximum stack size used by a program or I must 
look at the assembly code and start counting ?

3) Why :
   while (cnt--)
    {
      anything.....
    }

compiles using two comparisions of cnt  ?
    while (cnt)
    {
        cnt--;
         anything...
    }
works fine.

4) Why the flag -O1 generates a smaller code than -O2 and -Os ?

Thanks, Mauricio
