README
-----------------------------------------------------------------------
NOTICE: This is the README file for SGI Pro64(TM) compiler.
SGI Pro64 compiler is the ancestor of the Open64 compiler.
-----------------------------------------------------------------------
The SGI Pro64(TM) compiler suite includes optimizing compilers
and runtime support for C, C++, and Fortran90. These compilers
produce code that follows the Linux/IA-64 ABI. This means that
objects produced by the SGI compilers can link with objects
produced by other Linux/IA-64 compliant compilers such
as RedHat/Cygnus gcc and g++.
The latest information and updates for the Pro64 compilers will
eventually be found at http://oss.sgi.com/projects/Pro64. The rpm
included in this distribution represents a work in progress.
Please send problem reports to the mailing list described on
the SGI OSS Pro64 web site.
Language highlights:
C compatible with gcc
C++ compatible g++
Fortran90 with Fortran95 extensions
Optimization highlights:
Software pipelining:
At the -O2 and -O3 optimization levels the
compilers will use the IA-64 software pipelining instructions.
At the -O3 level a more powerful data dependence analysis will
be performed.
Interprocedural analysis and optimization
When -ipa is used on the command line, the compiler performs
interprocedural analysis and optimization.
Scalar Optimizations:
A partial list of optimizations performed include
Code motion
Constant propagation
Dead code elimination
Expression simplification
Common subexpression elimination
Strength reduction
Upcoming features
Exception handling for C++
OpenMP support in Fortran90
OpenMP support in C and C++
More optimizations
Installation Information
Untar the tar file that you downloaded from the ftp site:
% cd installation_directory
% gunzip pro64-0.01.0-13-sources.tar.gz
% tar xvf pro64-0.01.0-13-sources.tar
The pro64 compilers assume to be operating under an NUE
environment. Information about NUE can be found at:
http://www.software.hp.com/ia64linux
You need to install the pro64 rpm from the nue environment.
Note that the nue command will put you under your home
directory in NUE, which may not be your regular home
directory. You should move the pro64 rpm and osprey
source tree to a directory that is accessible under NUE.
To install the pro64 rpm do the following:
%su
#nue
#rpm -i --force --nodeps pro64-0.01.0-13.ia64.rpm
The --nodeps flag is needed because the installation
under NUE only sees files installed under NUE. It does
not see the files installed from the NUE rpm.
You can verify your installation by doing a simple
hello world test under NUE:
%cat hello.c
#include <stdio.h>
main()
{
printf("hello world\n");
}
%sgicc hello.c
%./a.out
hello world
%
The README.src file provides information about building the
pro64 compilers and libraries from the kpro64 source tree.
The sgicc(1), sgiCC(1) and sgif90(1) man pages provide information
about the SGI C, C++ and Fortran90 compiler commands.
