Subject: help on - how to specify architecture information to gcc
Date: Mon, 21 Sep 2009 11:52:00 -0000	[thread overview]
Message-ID: <25530300.post@talk.nabble.com> (raw)


Hi All,
         Our project is to optimize instruction scheduling in gcc. It
requires us to specify architecture information
(basically number of cycles per instruction, stall and branch delays)
to gcc, to optimize structural hazard detection.

Problem: Is there any specific format in which we can specify this
information to gcc? Is it possible to embed this additional
architecture specific detail, in .md files?

Target language for which optimization is being done: C
Target machine architecture: i686
GCC version: 4.4.1

         If none of the above options work, we were planning to put
the information manually in a file and make gcc read it each time it
loads. Any suggestions/comments on this approach?

         Couldn't find a related thread. Hence a new one.

Thanking All,
- Dhiraj.
