2011-01-22unifdef: update to upstream version 2.5Tony Finch1-63/+184
Fix a long-standing cpp compatibility bug. The -DFOO argument (without an explicit value) should define FOO to 1 not to the empty string. Add a -o option to support overwriting a file in place, and a -S option to list the nesting depth of symbols. Include line numbers in debugging output. Support CRLF newlines.

2009-12-12unifdef: update to upstream revision 1.190Tony Finch1-134/+207
Fix handling of input files (e.g. with no newline at EOF) that could make unifdef get into an unexpected state and call abort(). The new -B option compresses blank lines around a deleted section so that blank lines around "paragraphs" of code don't get doubled. The evaluator can now handle macros with arguments, and unbracketed arguments to the "defined" operator. Add myself to MAINTAINERS for unifdef.

2009-06-09kbuild: fix headers_exports with boolean expressionRussell King1-11/+37
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.

2006-09-25kbuild: add unifdefSam Ravnborg1-0/+998
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>
