====== Spec 2000 : cross compilation & results ======

The benchmarks bellow are statically compiled using the [[http://www.spec.org|Spec2000]] compilation process. The configuration files used to compile the suite are the following: {{i586.cfg}} and {{ppc.cfg}} and running:

  runspec -a build -c XXX.cfg

The i586 version is built using gcc, g++ and gfortran 4.1. The powerpc version is built with a gcc and g++ cross compilers version 3.4.5 with a glibc 2.3.2. The produced benchmarks are statically linked.


The following table provide the runnning time of the benchmarks in the suite for running the benchmark natively (i586), in a functional simulator (ppcemu) and in a cycle-level simulator (ppc-score). \\
Two diffrent data-set are provided: Test (the regular test data-set of the spec 2000) and tiny: a very small dataset built to keep small cycle-level simualtion time.

=== Legend ===

  * ''X'' : Some issues to compile this benchmark with a recent version of gcc, even on the native host.
  * ''SC!'' : Gap is using the unimplemented ''stat'' syscall.


=== tar.gz file ===

In each tar.gz file there is two binaries corresponding to the statically compiled benchmarks, and the file corresponding to the test data set. In each tar.gz, there is a ''run'' file describing what should be the command line to run the spec.
