patmos-benchmarks

===================

A collection of benchmarks and tests for the Patmos processor and compiler.

1. Requirements

• LLVM toolchain for Patmos (or either Sparc or PowerPc)

  • https://github.com/t-crest/patmos-llvm
  • https://github.com/t-crest/patmos-clang
  • https://github.com/t-crest/patmos-compiler-rt
  • https://github.com/t-crest/patmos-newlib
  • https://github.com/t-crest/patmos-gold
  • http://www.llvm.org/

• Absint a3 tools (optional)

  • http://www.absint.com/a3/index.htm

2. Configure, build and run tests

mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/patmos-clang-toolchain.cmake -DENABLE_TESTING=true
make
make test # (also via ctest, see ctest --help)

For a list of pre-defined compiler/processor toolchain configurations see the cmake directory (currently leon3-clang, mpc5554-clang, patmos-clang). To chose one of them use:

cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/<processor>-clang-toolchain.cmake

Additional search paths can be provided using the -DCMAKE_PROGRAM_PATH=<path> option.

List of CMake variables of interest:

• CMAKE_TOOLCHAIN_FILE ... toolchain to use
• ENABLE_TESTING ... enable tests
• ENABLE_CTORTURE ... enable gcc.c-torture (build time doubles)
• PLATIN_ENABLE_WCET ... enable WCET tests (currently patmos only)
• PLATIN_ENABLE_AIT ... enable WCET tests using absint's aiT tool (patmos only, requires a3)
• CONFIG_PML ... architecture configuration file (patmos only)

Patmos configuration

Some Patmos-specific options (e.g. method and stack cache related) for the Clang/LLVM compiler, the simulator (pasim) and WCET tool (platin) are controlled through architecture configuration files in YAML format, see the config-*.pml files in scripts/.

Have fun!

patmos-benchmarks's Issues

Licensing

Hello,

I'd like to know what is the license associated with the code of the benchmarks. I know that some of them have their own specific license, but is there a general license for the repository code? Or an easy way to find out which license is associated to each benchmark?

All I could find was a copyright disclaimer in the T-Crest website:

© 2012-2014 Copyright in all of the above documents and related software remains vested in the T-CREST Project Partners.

Does this apply to the patmos-benchmarks repository?

GCC testsuite no longer available through SVN

The nightly test cannot access GCC's svn repository to get the GCC test suite that we use for testing LLVM:

-- Found Subversion: /usr/bin/svn (found version "1.9.7") 
svn: E170013: Unable to connect to a repository at URL 'svn://gcc.gnu.org/svn/gcc/trunk/gcc/testsuite/gcc.c-torture/execute'
svn: E000101: Can't connect to host 'gcc.gnu.org': Network is unreachable

We are therefore down to only 118 tests from over 1000.

As far as I can tell, GCC has moved to git and apparently turned off their svn repository. Links to the svn repository redirect to their git help page.

We should fix the test to get the testsuite through git.

error while making the benchmarks

Hi,
I followed the README file and tried to make the benchmarks. However, it gives an error:

patmos-clang-3.4: error: no such file or directory: 'INCLUDES'
make[2]: *** [Debie1-e/code/patmos/clang/CMakeFiles/debie1-target.dir/target.c.bc] Error 1
make[1]: *** [Debie1-e/code/patmos/clang/CMakeFiles/debie1-target.dir/all] Error 2
make: *** [all] Error 2

I cound not find any directory named "INCLUDES" in any directory.
I have installed all the pre-requisites and included the paths as given in t-crest/patmos.
What am I missing here?
Thnaks,
Anwesha
