llvm dev - Jun 2014 - [LLVMdev] Python version requirement for LLVM

http://llvm.org/docs/GettingStarted.html currently mentions Python 2.5 as a
minimum required version. I'd like to use argparse
<https://docs.python.org/dev/library/argparse.html> in a script and be
able
to test this script. This requires Python 2.7. This version has been around
since 2010, and afaiu, is available on all modern platforms. Is there any
reason not to change minimum required version of Python to 2.7?

AFAIK, 2.5 is minimum for running automated tests with lit. If your script
does not run as part of lit, you are less constrained.

For instans, utils/sort_includes.py uses argparse

As much as I like killing support for Python 2.6 and below, RHEL is usually the
blocker. They still have 2.4 under support. Only the RHEL that was released a
few weeks ago finally has 2.7.

Yeah, RHEL... Then I'm going to add a lit feature (say, python27) to guard
the test of my python script on it with REQUIRES:.

Given the amount of complexity required to build LLVM & Clang (having the
right compiler & libstdc++ installed), compared to the 3 minutes it
typically takes to install any Python version on any Linux box, these
limitations always strike me as silly. But I gave up on this fight some
time ago.
