- # 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
