Re: Generating assembly for modulo scheduled loop for Itanium (fwd)

["Prof.Y.N.Srikant" <srikant at csa dot iisc dot ernet dot in>]

Dear Dr.Edelson,

My students forwarded the reply from you (below). Our institution, The
Indian Institute of Science is a premier post graduate educational and
research institution in India, offering degrees of various kinds. Please
see our home page: www.iisc.ernet.in for more details. You may also
contact Dr. Vivek Sarkar in your own organization (IBM Watson Center) for
more details on the Indian Institute of Science.

We would be certainly more than happy to offer the code we have developed
based on gcc. In fact, my students have been using gcc source code for
several projects such as SSA based optimizations, profiling and Itanium
code generation. We will certainly make all this code to the free software
foundation. 

The students, Deepak Naik and Ritu Sabharwal, who are working on the
software pipelining project for the Itanium are postgraduate students in
Computer Science. I would appreciate it very much if the clarifications
they have sought are provided early.

With best regards
srikant
