[llvm] r298603 - Do not polute the source directory.

[Vassil Vassilev via llvm-commits]

Author: vvassilev

New Revision: 298603

URL: http://llvm.org/viewvc/llvm-project?rev=298603&view=rev
Log:
Do not polute the source directory.

When a python script is run, by default it creates the bytecode file if the directory is writable, and this ‘pollutes’ source folders.

>From python's help:
-B Don’t write .py[co] files on import. See also PYTHONDONTWRITEBYTECODE.

Patch by Pere Mato (D30604)!
