very basic porting

[Gabriele Caracausi]

Hello All,

i'm working to Microchip PIC18 porting for university purposes...
I've written the four files (.h, .md, .c and protos), studied for 9 months
and created cc1 for pic18.

But when I try to assign a value to a variable the cc1 sends me an error in
prepare_cmp_insn - optabs.c (line 3505).
I've setted cmpqi e cmphi RTL patterns... but in your opinion, the problem
is in .md or in .h file? Or what can be the problem?

Someone has a very basic porting of other 8bit microcontrollers (like ip2k
or avr) to take as example to write the minimal set of code in .md and .h
files?


Thanks a lot.
Write me for all types of questions!
