* ldlex.l (INPUTLIST): New start condition.
(comment pattern, ",", "(", ")", "AS_NEEDED")
({FILENAMECHAR1}{FILENAMECHAR}*, "-l"{FILENAMECHAR}+)
(quoted string pattern, whitespace pattern): Add INPUTLIST to
valid start conditions.
(<INPUTLIST>"="{FILENAMECHAR1}{FILENAMECHAR}*): New NAME rule.
(ldlex_inputlist): New start-condition-setter function.
* ldgram.y (input_list1): Rename from input_list. All recursive
use changed.
(input_list): New wrapper rule for input_list1, setting
INPUTLIST lexer state for the duration of parsing input_list1.
All this to say INPUT(=/path/to/file) and not be forced to use
INPUT("=/path/to/file") whenever there's a need to force a sysroot-
prefix. Still, IMHO it seems better to make use of a previously
invalid syntax and not only change the meaning of quoted =-prefixed
paths (though arguably that's not very useful before this patchset).
This got a little bit hairier than I'd expected: I had to add a new
lexer state (aka. start condition) to avoid a first "=" being lexed as
the token "=", despite that not making sense in constructs expecting
file-names in the first place. (The grammar doesn't allow for
expressions in any part of those lists.) I guess I *could* have made
it work using that token anyway, but I didn't like the idea that you
would be able to separate the "=" from the rest of the file-name with
whitespace.
