| |
Hello,
Grepping through the sources I found 500+ occurrences of double exclamation marks before identifier names (such as !!x -- I took care to ignore occurrences of !! inside comment blocks, because there are plenty of that sort too).
!! are to be found even in the definitions of common macros such as likely() and unlikely(), which hundreds of eyes must have seen over the last year or so ...
Are all these occurrences merely the debris of s/something/!notsomething/g kind of patches or is there some dark, unknown C / gcc wizardry I have absolutely no clue of?
