glsl/glcpp: Add flex options to eliminate the default rule.
We've had multiple bugs in the past where we have been inadvertently matching
the default rule, (which we never want to do). We recently added a catch-all
rule to avoid this, (and made this rule robust for future start conditions).
Kristian pointed out that flex allows us to go one step better. This syntax:
%option warn nodefault
instructs flex to not generate the default rule at all. Further, flex will
generate a warning at compile time if the set of rules we provide are
inadequate, (such that it would be possible for the default rule to be
matched).
With this warning in place, I found that the catch-all rule was in fact
missing something. The catch-all rule uses a pattern of "." which doesn't
match newlines. So here we extend the newline-matching rule to all start
conditions. That is enough to convince flex that it really doesn't need
any default rule.

glsl/glcpp: Add a catch-all rule for unexpected characters.
In some of the recent glcpp bug-fixing, we found that glcpp was emitting
unrecognized characters from the input source file to stdout, and dropping

This was obviously confusing, and totally undesired.
The bogus behavior comes from an implicit default rule in flex, which is
that any unmatched character is implicitly matched and printed to stdout.
To avoid this implicit matching and printing, here we add an explicit

glsl/glcpp: Correctly parse directives with intervening comments
It's legal (though highly bizarre) for a pre-processor directive to look like
this:
# /* why? */ define FOO bar
This behavior comes about since the specification defines separate logical
phases in a precise order, and comment-removal occurs in a phase before the
identification of directives.
Our implementation does not use an actual separate phase for comment removal,
so some extra care is necessary to correctly parse this. What we want is for
'#' to introduce a directive iff it is the first token on a line, (ignoring
whitespace and comments). Previously, we had a lexical rule that worked only
for whitespace (not comments) with the following regular expression to find a
directive-introducing '#' at the beginning of a line:
HASH ^{HSPACE}*#{HSPACE}*
In this commit, we switch to instead use a simple literal match of '#' to
return a HASH_TOKEN token and add a new <HASH> start condition for whenever
the HASH_TOKEN is the first non-space token of a line. This requires the
addition of the new bit of state: first_non_space_token_this_line.
This approach has a couple of implications on the glcpp parser:
1. The parser now sees two separate tokens, (such as HASH_TOKEN and
HASH_DEFINE) where it previously saw one token (HASH_DEFINE) for
the sequence "#define". This is a straightforward change throughout
the grammar.
2. The parser may now see a SPACE token before the HASH_TOKEN token of
a directive. Previously the lexical regular expression for {HASH}
would eat up the space and there would be no SPACE token.
This second implication is a bit of a nuisance for the parser. It causes a
SPACE token to appear in a production of the grammar with the following two
definitions of a control_line:
control_line
SPACE control_line
This is really ugly, since normally a space would simply be a token
separator, so it wouldn't appear in the tokens of a production. This leads to
a further problem with interleaved spaces and comments:
/* ... */ /* ... */ #define /* ..*/
For this, we must not return several consecutive SPACE tokens, or else we would need an arbitrary number of new productions:
SPACE SPACE control_line
SPACE SPACE SPACE control_line
ad nauseam
To avoid this problem, in this commit we also change the lexer to emit only a
single SPACE token for any series of consecutive spaces, (whether from actual
whitespace or comments). For this compression, we add a new bit of parser
state: last_token_was_space. And we also update the expected results of all
necessary test cases for the new compression of space tokens.
Fortunately, the compression of spaces should not lead to any semantic changes
in terms of what the eventual GLSL compiler sees.
So there's a lot happening in this commit, (particularly for such a tiny
feature). But fortunately, the lexer itself is looking cleaner than ever. The
only ugly bit is all the state updating, but it is at least isolated to a
single shared function.
Of course, a new "make check" test is added for the new feature, (directives
with comments and whitespace interleaved in many combinations).

glsl/glcpp: Stop using a lexer start condition (<SKIP>) for token skipping.
Here, "skipping" refers to the lexer not emitting any tokens for portions of
the file within an #if condition (or similar) that evaluates to false.
Previously, the lexer had a special <SKIP> start condition used to control
this skipping. This start condition was not handled like a normal start
condition. Instead, there was a particularly ugly block of code set to be
included at the top of the generated lexing loop that would change from
<INITIAL> to <SKIP> or from <SKIP> to <INITIAL> depending on various pieces of
parser state, (such as parser->skip_state and parser->lexing_directive).
Not only was that an ugly approach, but the <SKIP> start condition was
complicating several glcpp bug fixes I attempted recently that want to use
start conditions for other purposes, (such as a new <HASH> start condition).
The recently added RETURN_TOKEN macro gives us a convenient way to implement
skipping without using a lexer start condition. Now, at the top of the
generated lexer, we examine all the necessary parser state and set a new
parser->skipping bit. Then, in RETURN_TOKEN, we examine parser->skipping to
determine whether to actually emit the token or not.
Besides this, there are only a couple of other places where we need to examine
the skipping bit (other than when returning a token):
* To avoid emitting an error for #error if skipped.
* To avoid entering the <DEFINE> start condition for a #define that is
skipped.
With all of this in place in the present commit, there are hopefully no
behavioral changes with this patch, ("make check" still passes all of the
glcpp tests at least).

r600g,radeonsi: switch all occurences of array_size to util_max_layer
This fixes 3D texture support in all these cases, because array_size is 1
with 3D textures and depth0 actually contains the "array size".
util_max_layer is universal and returns the last layer index for any texture
target.
A lot of the cases below can't actually be hit with 3D textures, but let's
be consistent.
This fixes a failure in:
piglit layered-rendering/clear-color-all-types 3d single_level

calculation.

assembles it's own ir.
There is a bit of additional renaming to s/fd3_compiler/ir3_compiler/,
