Hi Francois, Colm, I've read your emails and I'd like to be involved in this project.
As you can read in my past emails in the GCC ML, I've tried two years ago to create a porting of GCC to PIC 18FXXX. The project was developed when I was student without a truly and strong guide in all involved activities. My proposal is: I could share the code I've developed but, keep in mind, that the code should contain some error. Starting from it, we could continue / modify / correct / improve the porting all together. What do you think about it ? Ciao! Gabriele. -----Original Message----- From: Franзois Poulain [mailto:[EMAIL PROTECTED] Sent: Monday, March 06, 2006 7:56 PM To: Colm O' Flaherty Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: GCC Port (gcc backend) for Microchip PICMicro microcontroller > Like you, I'm still studying the internals of gcc, but I'm close to > being confident enough to start making some changes.
