Cool Tools - GCC for Sun® Systems
Description
GCC for Sun Systems extends GCC to be able to use the
optimizing Sun Code Generator for SPARC systems.
We encourage you to
download
GCCFSS 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). 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 Sun Systems follow the
same ABI as programs compiled by GCC. You can mix and match GCC for
Sun 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
problems.

We are proud to announce the availability of a new release of GCC for Sun Systems
release 4.3.2. This release incorporates the new features of GCC
4.3.2, bugs fixes, and the Thread
Analyzer.
The GCC for SPARC Systems releases 4.2.1, 4.2.0, 4.0.4 and 4.0.3 will remain
available.
The GCCFSS 4.2.1 cross compiler hosted on x86/Solaris systems is still available.
Go to the
4.2.1 Download instructions to obtain it.
The previous version of GCC for Sun Systems 4.2.0 was used to establish a world
records for single-chip and 4 processor integer performance using the
SPECint_rate2006 benchmark:
-
Using GCC for Sun 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].
-
Using GCC for Sun Systems 4.2.0 and Sun Studio 12, The Sun SPARC Enterprise
T5440 server, running at 1.4 GHz, deliverd a world record 4 processor
result of 301 SPECint_rate2006.
