BiSheng Autotuner

BiSheng Autotuner is a command-line tool (llvm-autotune) that enables a user to search for the optimal compiler optimization parameters for fine-grained code regions in a given program, via an iterative compilation process using BiSheng Compiler.

Quickstart

BiSheng Autotuner requires Python 3.10. Before installing the tool, make sure that python3 in your search path is the correct version of Python.

To start, run bin/install-autotuner.sh in the BiSheng Compiler installation directory. This will invoke pip to install Autotuner along with a number of dependencies. If the installation completes successfully, running bin/llvm-autotune -h should display a help message instead of an error.
