* Update to upstream version 2.7fanf2013-03-284-216/+416
| | | | | | | | | | | The most notable new feature is support for processing multiple files in one invocation. There is also support for more make-friendly exit statuses. The most notable bug fix is #line directives now include the input file name. Obtained from: http://dotat.at/prog/unifdef

* Update to upstream version 1.338fanf2010-02-192-27/+50
| | | | | | | | | | 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 support for CRLF newlines, based on a suggestion from Mark Rushakoff. Obtained from: http://dotat.at/prog/unifdef/

* Build usr.bin/ with WARNS=6 by default.ed2010-01-021-1/+0
| | | | Also add some missing $FreeBSD$ to keep svn happy.
* unifdef: fix invalid array access when nesting limit exceededfanf2009-11-271-4/+8
| | | | | | | | | | | | If the number of nested #if blocks exceeds 64, nest() increments the nesting depth and then reports an error. The message includes the line number for the start of the current #if block, which is read from past the end of the relevant array. Avoid the out-of-bounds read by reporting the error and exiting before the nesting depth has a chance to increase. Submitted by: Jonathan Nieder <jrnieder@gmail.com>
* unifdefall: optimise the loop that builds the unifdef command.fanf2009-11-261-9/+17
| | | | | | | | | | | | | | The old code used a shell loop to convert each controlling macro definition into a command-line argument, reading the macro definitions file each time. The new code converts the list of controlling macros into a sed script which can run through the list of macro definitions in one go. Add some explanatory comments, since the code is quite meta. Use {} instead of () for redirecting a group of commands. Submitted by: Jonathan Nieder <jrnieder@gmail.com>

* Update unifdef to my upstream version 1.188fanf2009-11-253-134/+300
| | | | | | | | | | | | | | | | | | | | | Main highlights: (A) The new -B option compresses blank lines around a deleted section so that blank lines around "paragraphs" of code don't get doubled. (B) Lenient evaluation of && and || so that #if expressions can be evaluated even when some of their sub-expressions cannot be. (C) The evaluator can now handle macros with arguments. (D) Portability fixes, especially for unifdefall.

| | | | | | | | | | | Allow the user to run unifdef without defining any symbols. This is useful in conjunction with the -k flag. Fix a bug in the -s handling code that would have caused out-of-bounds array accesses. Add a -n option to insert #line directives in the output. Ignore comment markers inside string and character literals (bug reported by Amos Shapira <amos.shapira@netregistry.com.au>). More accurate copyright notices.

| | | | | | | | | | | | | | | | | Fix the usage synopsis. Amend the copyright notice to reflect the fact that there's no Berkeley code left. Fix a typo in a comment, improve the descriptions of the way we use some global variables (relevant to the bug below), and note that division-by-zero has side effects so the current expression evaluator can't be trivially extended to arithmetic in its current design. Avoid hitting an abort(); /* bug */ when in "text mode" (i.e. ignoring comment state) by updating the line parser state properly. PR: 53907

| | | | | | | | | | | | | | | | | | | | | | | | | * The partial-evaluation of #elif sequences was broken and the spaghetti logic of its implementation was too hard to understand. I've re-done it using a straight-forward table-driven push-down automaton. * The pre-processor line parser did not allow for all of the weird places that people might put comments, which could have caused it to add syntax-errors to the output by removing a #if line containing the start- or end-marker of a comment. * The lexer didn't need to special-case the handling of string-literals or character-constants, but it did need to learn about line-continuations (backslash-newline). * The input routine was buggy and bit-rotten and trivially replacable with fgets(). I've also made the program static- and const-safe and improved the presentation-order. The formatting of the state-transition tables remains non-stylish.

* Upgrade unifdef:fanf2002-05-154-545/+997
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * It now knows about the existence of #elif which would have caused it to produce incorrect results in some situations. * It can now process #if and #elif lines according to the values of symbols that are specified on the command line. The expression parser is only a simple subset of what C allows but it should be sufficient for most real-world code (it can cope with everything it finds in xterm). * It has an option for printing all of the symbols that might control #if processing. The unifdefall script uses this option along with cpp -dM to strip all #ifs from a file. * It has much larger static limits. * It handles nested #ifs much more completely. There have also been many style improvements: KNF; ANSI function definitions; all global stuff moved to the top of the file; use stdbool instead of h0h0bool; const-correctness; err(3) instead of fprintf(stderr, ...); enum instead of #define; commentary. I used NetBSD's unifdef as the basis of this since it has received the most attention over the years. PR: 37454 Reviewed by: markm, dwmalone Approved by: dwmalone (mentor) MFC after: 3 weeks
