Russell King	eedc9d83ea	kbuild: fix headers_exports with boolean expression ... When we had code like this in a header unifdef failed to deduct that the expression was always false - and we had code exported that was not intended for userspace. #if defined(__KERNEL__) && !defined(__ASSEMBLY__) int a; #endif This commit implment support in unidef which allows it to work out if an #if expression always evaluates true or false for symbols which are being undefined/always defined. The patch is slightly more complicated than I'd hoped because unifdef needs to see lines fully evaluated - doing otherwise causes it to mark the line as "dirty" and copy it over no matter what.

Sam Ravnborg	01f1c8799a	kbuild: add unifdef ... This patch contains a raw copy of unifdef.c Next patch will modify it and add infrastructure to use it Adding unifdef to the kernel is acked by the author. The reason to add unifdef as part of the kernel source is that it is not yet a common utility on most distributions. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>	2006-09-25 09:00:00 +02:00
