Dave Malcolm added the comment: > Are you doing anything specific which requires this change? No. I was looking for ways of making CPython easier to debug, and I experimented with this. It didn't help with debuggability as much as I hoped. Given that CPython's performance is known to be sen

Antoine Pitrou added the comment: The assembler diff shows that at one point the compiler produced slightly less good code after the change. I don't know what the impact is in terms of performance but it shows we should be cautious with this change. Are you doing anything specific which require

[issue7543] RFE: introduce "enum Py_Opcode"

Dave Malcolm added the comment: Ooops, sorry; in an earlier version of this work, I was generating an enum of the form: enum { }; i.e. without an identifier (an anonymous enum) which I later changed to: enum Py_Opcode { }; Mea culpa; I forgot to update the text for this bug when I ma

[issue7543] RFE: introduce "enum Py_Opcode"

New submission from Dave Malcolm : Currently, Python's opcodes are defined as preprocessor #defines. This means that they are invisible to the debugger. I'm attaching: (i) a simple script (fixup-opcode-header.py) which converts Include/opcode.h to use an anonymous enum for the values (i
