Cool Tools - GCC for SPARC® Systems
Description
GCC for SPARC Systems extends GCC to be able to use the
optimizing Sun Code Generator for SPARC systems.
We encourage you to
download
the two tarballs and try it. The compiler commands are the same as
GCC: gcc and g++. All of the GCC command-line
options are there and MORE! Crank up the optimization level (-O3 and
-fast). Use interprocedural optimizations (-xipo). Use profile driven optimization
(-xprofile). And this is just the initial version! More optimizations will
follow shortly.
We have simplified the install. Just bunzip and untar into a directory
where you have write permission!! No need to be superuser.
Programs compiled with GCC for SPARC Systems follow the
same ABI as programs compiled by GCC. You can mix and match GCC for
SPARC Systems and GCC compiled objects.
Add yourself to the announce mailing list to keep up to date with the latest enhancements.
Participate in our GCCFSS Forum
discussions.
The GCCFSS Forum is also used to report

We are proud to announce the availability of GCC for SPARC Systems
release 4.2.0. This release incorporates the new features of GCC
4.2.0, bugs fixes, and the Thread
Analyzer. The installation procedure continues to be greatly
simplified. The GCC for SPARC Systems releases 4.0.4 and 4.0.3 will remain
available.
V4.2.0 takes performance record
We are proud to announce that GCC for SPARC Systems 4.2.0
has established a new world
record for single-chip integer performance using the
SPECint_rate2006 benchmark:
-
Using GCC for SPARC Systems 4.2.0,
The Sun SPARC Enterprise T5220 server,
running at 1.4 GHz, delivered a world record single chip result
of 83.2 SPECint_rate2006.
-
The Sun SPARC Enterprise
T5220 using the GCC for SPARC Systems (gccfss) compiler topped
all competitor's single chip results including beating the IBM
p570 single-chip 4.7 GHZ POWER6 result by 37%. IBM used its
proprietary compiler, XL C/C++ [1].
More details are
available.
