- """Here we have "scanners" for the different Python versions.
- "scanner" is a compiler-centric term, but it is really a bit different from
- a traditional compiler scanner/lexer.
- Here we start out with text disasembly and change that to be more
- ameanable to parsing in which we look only at the opcode name, and not
- and instruction's operand.
- In some cases this is done by changing the opcode name. For example
- "LOAD_CONST" it customized based on the type of its operand into
- "LOAD_ASSERT", "LOAD_CODE", "LOAD_STR".
- instructions that take a variable number of arguments will have the argument count
- suffixed to the opcode name. "CALL", "MAKE_FUNCTION", "BUILD_TUPLE", "BUILD_LIST",
- work this way for example
- We also add pseudo instructions like "COME_FROM" which have an operand
- Instead of full grammars, we have full grammars for certain Python versions
- and the others indicate differences between a neighboring version.
- For example Python 2.6, 2.7, 3.2, and 3.7 are largely "base" versions
- which work off of scanner2.py, scanner3.py, and scanner37base.py.
- Some examples:
- Python 3.3 diffs off of 3.2; 3.1 and 3.0 diff off of 3.2; Python 1.0..Python 2.5 diff off of
- Python 2.6 and Python 3.8 diff off of 3.7
