Difficult to suggest how long it would take. It depends on a lot of things like your knowledge and experience with compilers, C language and computer architecture, the architecture of the Processor and the complexity involved. If it is similar to the standard processors, then, the port is a fairly simple one.Hello, I like to port complete gcc tool-chain including gas,gasp,ld,binutils... to a custom CPU. May I request the mailing list the following:
(1) I intend doing it as a single man during
leisure time. Please suggest me in approximately how
much time (in terms of hours) can I expect this port
to complete.
(2) Where can I find the documentation and other
resources regarding how to do the port.
An excellant link is: http://www.le-hacker.org/hacks/projects/microprocessor/compiler.html And ofcourse, you always have the colossal documentation from gnu site. http://gcc.gnu.org/onlinedocs/gcc-2.95.3/gcc.html or something similar Finally, last but not the least..... try this: http://gcc.gnu.org/readings.html where you find links to lots of stuff:::: Of special interest among them is: Porting GCC for Dunces by Hans-Peter Nilsson.
(3) The goal is to port the tool-chain and build
operating systems like RTEMS, Linux etc. for this CPU.
A good idea.
I will be very thankful to receive some broad
suggestions.
You are always welcome.
