In data compression, BCJ, short for Branch-Call-Jump, refers to a technique that improves the compression of machine code of executable binaries by replacing relative branch addresses with absolute ones. This allows a LZMA compressor to identify duplicate targets and archive higher compression rate.
BCJ is used in 7-zip compression utility as default filter for executable binaries.
pybcj is a python bindings with BCJ implementation by C language. The C codes are derived from p7zip, portable 7-zip implementation. pybcj support Intel/Amd x86/x86_64, Arm/Arm64, ArmThumb, Sparc, PPC, and IA64.
A development status is considered as Beta
state.
As usual, you can install pybcj using python standard pip command.
.. code-block::
pip install pybcj
Alternatively, one can also use conda:
.. code-block::
conda install -c conda-forge pybcj
SETUPTOOLS_USE_DISTUTILS=stdlib
to install.
