v7.00 optimized integer division bug

[janni]

Just to keep reminding that it'd be good to fix old errors - optimization of integer division by powers of two still doesn't work correctly for all signed types (short, integer, longint) when dividend is not a multiple of divisor, for example, if int_var=-1 then int_var/8 gives -1 instead of 0.

Hi,

Is this the same issue as reported in the link below ?

Hi Filip,

As it happens, yes. Though the list is for PIC, not dsPIC compilers, this issue is common to both.
