FW: Request for help regarding the GNU gcc code generator

[Ravindra Naik]

Hello
I am interested in creating/developing code generator for gcc, for a
specific hardware (proprietary hardware); thus interested in developing a
cross-compiler for a platform not supported by GCC currently.
I have heard that there exists a facility in gcc whereby I can specify the
details of hardware in some configuration/specification file, so that the
code-generator (or atleast part of the code-generator) gets generated. I am
aware that gcc does indeed generate code for a variety of hardware
configurations, but the hardware I am interested in is a proprietary
hardware, and does not fit into the existing set of CPUs supported by gcc.

I am interested to know whether such a facility exists and where can I find
the relevant information.

Regards
RDNaik

      Yes, you should write a machine description in the subdirectory
config/[your_machine_name]. You will find all the necessary documentation at
http://gcc.gnu.org/onlinedocs/gcc_toc.html . The most interesting file for
you will
probably be http://gcc.gnu.org/onlinedocs/gcc_16.html . When you start
writing your
machine description, I recommend that you take a look in the config/
subdirectory at how the things are done for other (more or less similar)
architectures.

      Regards,
           Virgil.

The GCC manual contains a lot of information about porting GCC.  There
are some additional references in the Readings web-page of
gcc.gnu.org.

Hello

I am interested in knowing the procedure for plugging the h/w configuartion
for a proprietary machine so that GCC compiler can generate the code for
that hardware. Where can I find the complete docuemntation for the same?
Information will be greatly appreciated.
