Portable Efficient Assembly Codegen in Higher-level Python

Portable Efficient Assembly Code-generator in Higher-level Python (PEACH-Py) PEACH-Py is a Python framework for writing high-performance assembly kernels. PEACH-Py is developed to simplify writing optimized assembly kernels while preserving all optimization opportunities of traditional assembly. Some PEACH-Py features: - Automatic register allocation - Stack frame management, including re-aligning of stack frame as needed - Generating versions of a function for different calling conventions from the same source (e.g. functions for Microsoft x64 ABI and System V x86-64 ABI can be generated from the same source) - Allows to define constants in the place where they are used (just like in high-level languages) - Tracking of instruction extensions used in the function. - Multiplexing of multiple instruction streams (helpful for software pipelining)
