on Ubuntu:

• clang-4.0
• python2
• libclang-dev
• make sure to have the clang lib and clang python bindings in sync, same version
  • pip install https://pypi.python.org/packages/source/c/clang/clang-3.8.tar.gz

usage: modelparser [-h] [-v] [-b] [-m MODEL]

Parse reference implementations of custom extension models.

optional arguments:
-h, --help show this help message and exit
-v, --verbosity Increase output verbosity.
-b, --build If set, Toolchain and Gem5 will be rebuild.
-m MODEL, --model MODEL Reference implementation

The project is structured as follows:

• modelparsing/ - contains model parsing facilities
• tst/ - contains unit test for parser modules
• extensions/ - default place, where extension models should be defined
• riscv-opcodes/ - the riscv opcodes generator project, used by this project
