commit eeed9cc785ca447868967e5c84dae63e9ca8e6c2
Author: Hans-Peter Nilsson <hp@bitrange.com>
Date: Wed Oct 15 03:10:25 2014 +0200
Allow unquoted = as the first character in ldscript input_list names
* 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.

If "=" is the first character in a ldscript input file, force a sysroot prefix.
* ldlang.c (lang_add_input_file): If the first character in the
filename is '=', prepend the sysroot and force the context of that
input file to non-sysroot.
The "input_flags.sysrooted = 0" thing described in the comment is
covered by the testsuite part ("root-anchored =-prefixed script
inside"), but only observable for --with-sysroot configurations.

Add sysroot-prefix ld linker tests.
* ld-scripts/sysroot-prefix.exp, ld-scripts/sysroot-prefix-x.s,
ld-scripts/sysroot-prefix-y.s: New files.
N.B: full coverage is only possible with complementary use of
--with-sysroot when configuring.

ld.texinfo: "=" path-prefix forces sysroot in scripts not only SEARCH_DIR
* ld.texinfo (input files in linker scripts): When mentioning
behavior of first character "/" on scripts within sysroot, also
mention that effect can be forced by prefixing with "=" and
refer to SEARCH_DIR.

ld.texinfo: Clarify that sysroot affects "=" expansion.
* ld.texinfo (Options): When mentioning "=" and sysroot, mention
that --sysroot controls it, not only through the configuration.
