* Re-apply fixed r354847Conrad Meyer2019-11-201-56/+86
| | | | | | | | | | | | | | | | | unifdef(1): Improve worst-case bound on symbol resolution Use RB_TREE to make some algorithms O(lg N) and O(N lg N) instead of O(N) and O(N^2). While here, remove arbitrarily limit on number of macros understood. Reverts r354877 and r354878, which disabled the (correct) test.

* unifdef(1): Improve worst-case bound on symbol resolutionConrad Meyer2019-11-191-56/+73
| | | | | | | | | | | | Use RB_TREE to make some algorithms O(lg N) and O(N lg N) instead of O(N) and O(N^2). Because N is typically small and the former linear array also has great constant factors (as a property of CPU caching), this doesn't provide material benefit most or all of the time. While here, remove arbitrarily limit on number of macros understood. Notes: svn path=/head/; revision=354847

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-273-2/+8
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

* unifdef: fix invalid array access when nesting limit exceededTony Finch2009-11-271-4/+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.

* unifdefall: optimise the loop that builds the unifdef command.Tony Finch2009-11-261-9/+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> Notes: svn path=/head/; revision=199842

* Update unifdef to my upstream version 1.188Tony Finch2009-11-253-134/+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.

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 Notes: svn path=/head/; revision=117076
