* glsl: Add an internal-error catch-all ruleCarl Worth2014-07-291-0/+13
| | | | | | | | | | | | | | | | This is to avoid the default, silent flex rule which simply prints the character to stdout. For the following Khronos GLES3 conformance tests: invalid_char_in_name_vertex invalid_char_in_name_fragment With this commit, these tests now report Pass where they previously reported Fail, but Mesa isn't behaving correctly yet. It's now reporting the internal error where what is really desired is a syntax error. Reviewed-by: Jordan Justen <[email protected]>
* glsl/glcpp: Correctly parse directives with intervening commentsCarl Worth2014-07-2916-110/+242
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Rename HASH token to HASH_TOKENCarl Worth2014-07-292-5/+8
| | | | | | | | | | | This is in preparation for the planned addition of a new <HASH> start condition to the lexer. Both start conditions and token types are, of course, in the same default C namespace, so a start condition and a token type with the same name will collide. (And unfortunately, they are both apparently implemented as equivalent numeric types so the collision is undetected at compile time and simply leads to unpredictable behavior at run time.)

* glsl/glcpp: Don't use start-condition stack when switching to/from <DEFINE>Carl Worth2014-07-291-3/+3
| | | | | | | | | | | | | | | | | | | | | This commit does not cause any behavioral change for any valid program. Prior to entering the <DEFINE> start condition, the only valid start condition is <INITIAL>, so whether pushing/popping <DEFINE> onto the stack or explicit returning to <INITIAL> is equivalent. The reason for this change is that we are planning to soon add a start condition for <HASH> with the following semantics: <HASH>: We just saw a directive-introducing '#' <DEFINE>: We just saw "#define" starting a directive With these two start conditions in place, the only correct behavior is to leave <DEFINE> by returning to <INITIAL>. But the old push/pop code would have returned to the <HASH> start condition which would then cause an error when the next directive-introducing '#' would be encountered.

* glsl/glcpp: Fix off-by-one error in column in first-line error messagesCarl Worth2014-07-2917-19/+19
| | | | | | | | | | | | | | For the first line we were initializing the column to 1, but for all subsequent lines we were initializing the column to 0. The column number is advanced for each token read before any error message is printed. So the 0 value is the correct initialization, (so that the first column is reported as column 1). With this extremely minor change, many of the .expected files are updated such that error messages for the first line now have the correct column number in them.

* glsl/glcpp: Stop using a lexer start condition (<SKIP>) for token skipping.Carl Worth2014-07-293-63/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* glsl/glcpp: Drop extra, final newline from most outputCarl Worth2014-07-29130-165/+51
| | | | | | | | | | | | | | | | | | | | The glcpp parser is line-based, so it needs to see a NEWLINE token at the end of each line. This causes a trick for files that end without a final newline. Previously, the lexer for glcpp punted in this case by unconditionally returning a NEWLINE token at end-of-file, (causing most files to have an extra blank line at the end). Here, we refine this by lexing end-of-file as a NEWLINE token only if the immediately preceding token was not a NEWLINE token. The patch is a minor change that only looks huge for two reasons: 1. Almost all glcpp test result ".expected" files are updated to drop the extra newline. 2. All return statements from the lexer are adjusted to use a new RETURN_TOKEN macro that tracks the last-token-was-a-newline state. Reviewed-by: Jordan Justen <[email protected]>
* glsl/glcpp: Add testing for EOF sans newline (and fix for <DEFINE>, <COMMENT>)Carl Worth2014-07-297-2/+13
| | | | | | | | | | | | | | | | The glcpp implementation has long had code to support a file that ends without a final newline. But we didn't have a "make check" test for this. Additionally, the <EOF> action was restricted only to the <INITIAL> state so it would fail to get invoked if the EOF was encountered in the <COMMENT> or the <DEFINE> case. Neither of these was a bug, per se, since EOF in either of these cases is an error anyway, (either "unterminated comment" or "missing macro name for #define"). But with the new explicit support for these cases, we not generate clean error messages in these cases, (rather than "unexpected $end" from before). Reviewed-by: Jordan Justen <[email protected]>
* glsl/glcpp: Remove some un-needed calls to NEWLINE_CATCHUPCarl Worth2014-07-291-4/+0
| | | | | | | | | | | | | | | | | The NEWLINE_CATCHUP code is only intended to be invoked after we lex an actual newline character ('\n'). The two extra calls here were apparently added accidentally because the pattern happened to contain a (negated) '\n', (see commit 6005e9cb283214cd57038c7c5e7758ba72ec6ac2). I don't think either case could have caused any actual bug. (In the first case, the pattern matched right up to the next newline, so the NEWLINE_CATCHUP code was just about to be called. In the second case, I don't think it's possible to actually enter the <SKIP> start condition after commented newlines without any intervening newline.) But, if nothing else, the code is cleaner without these extra calls. Reviewed-by: Jordan Justen <[email protected]>
* glsl/glcpp: Add support for comments between #define and macro identifierCarl Worth2014-07-293-2/+41
| | | | | | | | | | | | | | | The recent adddition of an error for "#define followed by a non-identifier" was a bit to aggressive since it used a regular expression in the lexer to flag any character that's not legal as the first character of an identifier. But we need to allow comments to appear here, (since we aren't removing comments in a preliminary pass). So we refine the error here to only flag characters that could not be an identifier, nor a comment, nor whitespace. We also augment the existing comment support to be active in the <DEFINE> state as well. Reviewed-by: Jordan Justen <[email protected]>
* glsl/glcpp: Emit proper error for #define with a non-identifierCarl Worth2014-07-293-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, if the preprocessor encountered a #define with a non-identifier, such as: #define 123 456 The lexer had no explicit rules to match non-identifiers in the <DEFINE> start state. Because of this, flex's default rule was being invoked, (printing characters to stdout), and all text was being discarded by the compiler until the next identifier. As one can imagine, this led to all sorts of interesting and surprising results. Fix this by adding an explicit rule complementing the existing identifier-based rules that should catch all non-identifiers after #define and reliably give a well-formatted error message. A new test is added to "make check" to ensure this bug stays fixed. This commit also fixes the following Khronos GLES3 CTS test: define_non_identifier_vertex (The "fragment" variant was passing earlier only because the preprocessor was behaving so randomly and causing the compilation to fail. It's lucky, in fact, that the "vertex" version succesfully compiled so we could find and fix this bug.) Reviewed-by: Jordan Justen <[email protected]>

* glsl/glcpp: Fix to emit spaces following directivesCarl Worth2014-07-292-2/+3
| | | | | | | | | | | | | The glcpp lexer and parser use the space_tokens state bit to avoid emitting tokens for spaces while parsing a directive. Previously, this bit was only being set again by the first non-space token following a directive. This led to a bug where a space, (or a comment that should emit a space), immediately following a directive, (optionally searated by newlines), would be omitted from the output. Here we fix the bug by also setting the space_tokens bit whenever we lex a newline in the standard start conditions.
