Porting Question

[Viktor Pobedin]

Peter,

I don't think that there is a complete howto document exists that explains
all the 
aspects of porting of the gcc to the new architecture. However on the Bombay

Institute site you can find slides that contain a good explanation of the
structure 
of the gcc in general and md files in particular. I would recommend to do
the porting 
in the following steps:
1. Study the papers from the links above :
http://www.cse.iitb.ac.in/grc/gcc-workshop-12/index.php?page=slides
http://www.cse.iitb.ac.in/grc/intdocs/incrementalMD.pdf
2. Choose the target from gcc/config that most similar to your architecture
and use it as 
a baseline for your project.
3. Get all the additional information from the gccint spec - it has a good
explanation about all 
the hooks and md file that you'll need to implement.

BR, Viktor.

Hi,

Is there any HowTo or Tutorial
for writing Machine-Descriptions
beside gccint and pgccfd.
