The use of com_node() introduces a lot of extra stack frames, enough to cause a stack overflow compiling test.test_parser with the standard interpreter recursionlimit. The com_node() is a convenience function that hides the dispatch details, but comes at a very high cost. It is more efficient to dispatch directly in the callers. In these cases, use lookup_node() and call the dispatched node directly. Also handle yield_stmt in a way that will work with Python 2.1 (suggested by Shane Hathaway) |

This directory contains modules for a a Python source to bytecode compiler written in pure Python. To install the compiler modules so they're available for use by third-party Python software, run 'python setup.py install'. compile.py Demo that compiles a Python module into a .pyc file using the pure-Python compiler code. demo.py Prints the names of all the methods defined in a module, as a demonstration of walking through the abstract syntax tree produced by the parser. dumppyc.py Dumps the contents of a .pyc file, printing the attributes of the code object followed by a code disassembly. regrtest.py Runs the Python test suite using bytecode generated by the pure-Python compiler code instead of the builtin compiler. setup.py Setup file for installing the compiler code as a package.
