[Mesa-dev] [PATCH 2/5] nir: use Python to autogenerate opcode information

[ahmad]

hi.

"#! /usr/bin/env python" corresponds python 3.x series for some  major distro (arch,fedora ...) and python 2.x for some others. 

python 2.x and python 3.x are not source compatible each other.

python 3.x not contains "xrange" funcion anymore.

range vs xrange only meaningfull for python 2.x.

Distros that which still use 2.x  series as default python interpreter going to 3.x. 

regargs.
