Portable Efficient Assembly Codegen in Higher-level Python (Python 3)

 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)
  * Allow one 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)
 .
 This package installs the library for Python 3.
