From: Mathieu Bridon Date: Mon, 25 Jun 2018 16:31:01 +0000 (+0200) Subject: python: Explicitly add the 'L' suffix on Python 3 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ad363913e6766280f53838126d67370f9e97aa12;p=mesa.git python: Explicitly add the 'L' suffix on Python 3 Python 2 had two integer types: int and long. Python 3 dropped the latter, as it made the int type automatically support bigger numbers. As a result, Python 3 lost the 'L' suffix on integer litterals. This probably doesn't make much difference when compiling the generated C code, but adding it explicitly means that both Python 2 and 3 generate the exact same C code anyway, which makes it easier to compare and check for discrepencies when moving to Python 3.
