[PATCH] D154987: [lit] Implement PYTHON directive and config.prologue

[James Henderson via Phabricator via llvm-commits]

jhenderson added a comment.

Just chiming in here to give my 2p. lit already has the ability to execute python scripts (call `%python`), but any such scripts are not directly tied into the lit, so running them etc won't produce output that fits with the lit diagnostics, as I understand it. As I understand it, this patch is essentially just an improvement of the "execute arbitrary python script" option. I'm in favour of it, but if it isn't already clear, I think it would be worth outlining in this patch why simply calling an external python script (which could actually be embedded within the file) is insufficient for the motivating case.
