#!/usr/bin/perl # # Original version were part of Gerd Knorr's v4l scripts. # # Several improvements by (c) 2005-2007 Mauro Carvalho Chehab # # Largely re-written (C) 2007 Trent Piepho # Stolen for DRM usage by airlied # # Theory of Operation # # This acts as a sort of mini version of cpp, which will process # #if/#elif/#ifdef/etc directives to strip out code used to support # multiple kernel versions or otherwise not wanted to be sent upstream to # git. # # Conditional compilation directives fall into two catagories, # "processed" and "other". The "other" directives are ignored and simply # output as they come in without changes (see 'keep' exception). The # "processed" variaty are evaluated and only the lines in the 'true' part # are kept, like cpp would do. # # If gentree knows the result of an expression, that directive will be # "processed", otherwise it will be an "other". gentree knows the value # of LINUX_VERSION_CODE, BTTV_VERSION_CODE, the KERNEL_VERSION(x,y,z) # macro, numeric constants like 0 and 1, and a few defines like MM_KERNEL # and STV0297_CS2. # # An exception is if the comment "/*KEEP*/" appears after the expression, # in which case that directive will be considered an "other" and not # processed, other than to remove the keep comment. # # Known bugs: # don't specify the root directory e.g. '/' or even '////' # directives continued with a back-slash will always be ignored # you can't modify a source tree in-place, i.e. source dir == dest dir use strict;
