| # Below, we strip out all but preprocessor directives. | ||
| # We have to take care of situations like | ||
| # #if defined(FOO) BAR /* comment line 1 | ||
| # more comment lines */ | ||
| # If we just delete text starting from the '/*' to the end of line, we will | ||
| # screw up cases like | ||
| # #if defined(FOO) /* comment */ \ | ||
| # && defined(BAR) /* comment */ \ | ||
| # && defined(BAZ) /* comment */ \ | ||
| # etc. | ||
| # Also, in lines like | ||
| # #defined FOO(a,b) a/**/b | ||
| # the comment may be important and so needs to be retained. | ||
| # This code processes the single-line comments first; it assumes there is | ||
| # at most one straightforward comment per continued preprocessor line, | ||
| # replacing each non-empty comment (and its surrounding white space) by a | ||
| # single space. (sed only has a greedy '*' quantifier, so this doesn't | ||
| # work right if there are multiple comments per line, and strings can look | ||
| # like comments to it; both are unlikely in a preprocessor statement.) Any | ||
| # continuation line is joined, and the process repeated on the enlarged | ||
| # line as long as there are continuations. At the end, if there are any | ||
| # comments remaining, they are either completely empty or are like the | ||
| # first situation. The latter are just deleted by first deleting to the | ||
| # end of line (including preceding white space) things that start with '/*' | ||
| # and the next char isn't a '*'; then things that start with '/**', but the | ||
| # next char isn't a '/'. (Subsequent lines of the comment are irrelevant | ||
| # and get dropped.) At the end, we unjoin very long lines to avoid | ||
| # preprocessor limitations | ||
