2019-08-03Fix crash introduced by #30Andrew Waterman1-1/+1
2019-08-03(Partially) fix #30 (#31)Tommy Thorn3-42/+47
* (Partially) fix #30 With this change (and a renamed parse-opcodes) it's possible to as a Python module without having to patch the repo. Example: from parse_opcodes import parse_inputs if __name__ == "__main__": (namelist, pseudos, mask, match, arguments) = parse_inputs(["opcodes", "opcodes-rvc"]) * Fix #30: Rename parse-opcode to parse_opcode to enable module use

2019-02-28Read opcodes from files (#23)Pavel I. Kryukov1-61/+74
Current generation flow assumes that opcodes are provided in a `cat ./opcodes | ./parse_opcodes -c' manner. However, Windows CMD has no `cat' command, and it uses `type' instead, so implementation of cross-platform script is complicated. In this patch, we allow parsing opcode files directly by Python, if their names are provided as a command line arguments, not depending on the host shell. If no arguments are passed, script behaves as usual, reading opcodes from the stdin.

2018-09-20Add header following Go convention for generated code (#21)Tobias Klauser1-1/+1
Go has a convention for generated code comments (https://golang.org/s/generatedcode), i.e. they must match the regex ^// Code generated .* DO NOT EDIT\.$ Adjust the generated header to follow this convention.
