* glsl/build: Build glcpp via the glsl MakefileMatt Turner2013-01-221-2/+2
| | | | | | Removing the subdirectory recursion provides a small speed up. Tested-by: Andreas Boll <[email protected]>
* glcpp: Add tests for line continuationCarl Worth2013-01-114-0/+46
| | | | | | | | | First we test that line continuations are honored within a comment, (as recently changed in glcpp), then we test that line continuations can be disabled via an option within the context. This is tested via the new support for a test-specific command-line option passed to glcpp. Reviewed-by: Kenneth Graunke <[email protected]>
* glcpp: Allow test-specific arguments for standalone glcpp testsCarl Worth2013-01-111-2/+9
| | | | | | | | This will allow the test exercising disabled line continuations to arrange for the --disable-line-continuations argument to be passed to the standalone glcpp. Reviewed-by: Kenneth Graunke <[email protected]>
* glcpp: Add test involving token pasting of INTEGER tokens.Carl Worth2012-11-292-0/+15
| | | | | | | | | | | | | | | This test file is very similar to test 113-line-and-file-macros but uses token pasting for cleaner quiz answers (without spaces between the digits). This test passes thanks to the recent addition of support for pasting INTEGER tokens, (but would have failed without that). (Note that this test is distinct from test 059-token-pasting-integer which pastes integers parsed from the source. Those are parsed to INTEGER_STRING tokens and are already pasted correctly as verified by that test. The only way to generate the INTEGER tokens which currently fail to paste is with an internal define such as __LINE__ that results in an integer.) Reviewed-by: Matt Turner <[email protected]>
* glcpp: Extend the invalid-paste testCarl Worth2012-11-292-0/+20
| | | | | | | | The current code lets a few invalid pastes through, such as an string pasted onto the end of an integer. Extend the invalid-paste test to catch some of these. Reviewed-by: Matt Turner <[email protected]>
* glcpp: Add support for __LINE__ and __FILE__ macrosCarl Worth2012-11-292-0/+15
| | | | | | | | | | | | | These tokens are easy to expand by just looking at the current, tracked location values, (and no need to look anything up in the hash table). Add a test which verifies __LINE__ with several values, (and verifies __FILE__ for the single value of 0). Our testing framework isn't sophisticated enough here to have a test with multiple file inputs. This commit fixes part of es3conform's preprocess16_frag test.

| | | | | | | | | | | | | | By moving the HASH_LINE rule out of control_line: and into line:, we avoid adding control_line's additional \n (as seen in the first hunk). mattst88: Carl and I determined independently of Fabian that the 091 test needed to be modified identically to this, and our patch to fix the test was more complicated.

* glcpp: Reject garbage after #else and #endif tokensMatt Turner2012-11-094-0/+11
| | | | | | | | | | | | | | | | | | | | | | Previously we were accepting garbage after #else and #endif tokens when the previous preprocessor conditional evaluated to false (eg, #if 0). When the preprocessor hits a false conditional, it switches the lexer into the SKIP state, in which it ignores non-control tokens. The parser pops the SKIP state off the stack when it reaches the associated #elif, #else, or #endif. Unfortunately, that meant that it only left the SKIP state after the lexing the entire line containing the #token and thus would accept garbage after the #token. To fix this we use a mid-rule, which is executed immediately after the #token is parsed.

* glsl: glcpp: Move handling of #line directives from lexer to parser.Carl Worth2012-06-261-4/+4
| | | | | | | | | | | | | | | | | | | The GLSL specification requires that #line directives be interpreted after macro expansion. Our existing implementation of #line macros in the lexer prevents conformance on this point. Moving the handling of #line from the lexer to the parser gives us the macro expansion we need. An additional benefit is that the preprocessor also now supports comments on the same line as #line directives. Finally, the preprocessor now emits the (fully-macro-expanded) #line directives into the output. This allows the full GLSL compiler to also see and interpret these directives so it can also generate correct line numbers in error messages.

* glsl: glcpp: Allow "#if undefined-macro' to evaluate to false.Carl Worth2012-06-264-3/+17
| | | | | | | | | | | | | | | | | A strict reading of the GLSL specification would have this be an error, but we've received reports from users who expect the preprocessor to interepret undefined macros as 0. This is the standard behavior of the rpeprocessor for C, and according to these user reports is also the behavior of other OpenGL implementations. So here's one of those cases where we can make our users happier by ignoring the specification. And it's hard to imagine users who really, really want to see an error for this case. The two affected tests cases are updated to reflect the new behavior. Signed-off-by: Carl Worth <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

The logic is now (tests-passed AND (!valgrind OR valgrind-tests-passed)) which lets us return success if the valgrind tests aren't run.

* glcpp: Add a test for #elif with an undefined macro.Carl Worth2011-09-302-0/+8
| | | | | | | | | | | | | | | | | | As written, this test correctly raises an error for #elif being used with an undefined macro (and not as an argument to "defined"). If the preceding #if were '#if 1' then this diagnositc would correctly be hidden. That allows code such as the following to not raise an error: #ifndef MAYBE_UNDEFINED #elif MAYBE_UNDEFINED < 5 ... #endif So this test case is working as expected already.

* Add expected file for 095-recursive-define test case.Carl Worth2011-04-141-0/+4
| | | | | | | | | | It's clear enough that the current segmentation fault isn't what we want. And it's also very easy to know what we do want here, (just check with any functional C preprocessor such as "gcc -E"). Add the desired output as an expected file so that the test suite gives useful output, (showing the omitted output and the segfault), rather than just reporting "No such file" for the expected file.
* glcpp: Add --valgrind option to the glcpp-test utilityCarl Worth2011-04-141-16/+46
| | | | | | | | | | | The common case for this test suite is to quickly test that everything returns the correct results. In this case, the second run of the test suite under valgrind was just annoying, (and the user would often interrupt it). Now, do what is wanted in the common case by default (just run the test suite), and require a run with "glcpp-test --valgrind" in order to test with valgrind.
* Add an expected file for 084-unbalanced-parenthesesCarl Worth2011-04-141-0/+2
| | | | | | | | | | | | The expected file here captures the current behavior of glcpp (which is to generate an obscure "syntax error, unexpected $end" diagnostic for this case). It would certainly be better for glcpp to generate a nicer diagnostic, (such as "missing closing parenthesis in function-like macro definition" or so), but the current behavior is at least correct, and expected. So we can make the test suite more useful by marking the current behavior as expected.
* Add an expected file for 094-divide-by-zero-short-circuitCarl Worth2011-04-142-0/+26
| | | | | | | | | | | The expected file here captures the current behavior of glcpp (which is to generate a division-by-zero error) for this case. It's easy to argue that it should be short-circuiting the evaluation and not generating the diagnostic (which happens to be what gcc does). But it doesn't seem like we should force this behavior on our pre-processor, (and, as always, the GLSL specification of the pre-processor is too vague on this point).
* Add an expected file for 093-divide-by-zeroCarl Worth2011-04-141-0/+4
| | | | | | This test is behaving just fine already---it's generating an informative diagnostic, ("error: division by 0 in preprocessor directive"), so adding this in the expected file makes things pass.
* glcpp/tests: Update 063-comments.c.expected to match output.Kenneth Graunke2011-03-031-0/+7

* Revert "glcpp: Demote "macro redefined" from an error to a warning"Carl Worth2011-01-291-6/+6
| | | | | | | | This reverts commit d3df641f0aba99b0b65ecd4d9b06798bca090a29. The original commit had sat unpushed on my machine for months. By the time I found it again, I had forgotten that we had decided not to use this change after all, (the relevant test was removed long ago).
* glcpp: Demote "macro redefined" from an error to a warningCarl Worth2011-01-281-6/+6
| | | | | | | | | | The GLSL specification is vague here, (just says "as is standard for C++"), though the C specifications seem quite clear that this should be an error. However, an existing piglit test (CorrectPreprocess11.frag) expects this to be a warning, not an error, so we change this, and document in README the deviation from the specification.

* glcpp: Fix test suite to avoid flagging failed tests as valgrind errors.Carl Worth2010-08-231-4/+5
| | | | | | | | | | We recently added several tests that intentionally trigger preprocessor errors. During valgrind-based testing, our test script was noticing the non-zero return value from the preprocessor and incorrectly flagging the valgrind-based test as failing. To fix this, we make valgrind return an error code that is otherwise unused by the preprocessor.
* glcpp: Add new test for #line directive.Carl Worth2010-08-232-0/+21
| | | | | | | | | | | | This test exposes two current bugs: 1. The source number is not being correctly emitted in error messages (instead, it's always 0). 2. A directive of "#line 0" is resulting in the following parse error: preprocessor error: Invalid tokens after #
* glcpp: Add test for the #error directive.Carl Worth2010-08-232-0/+4
| | | | | | | This directive is already implemented nicely, but wasn't previously tested. It will be convenient to use this directive in further tests that rely on error messages, (such as ensuring that #line correctly sets the line number in the error message).
* glcpp: Add two new tests for testing redefined macros.Carl Worth2010-08-174-0/+58
| | | | | | The specification says that redefining a macro is an error, unless the new definitions is identical to the old one, (identical replacement lists but ignoring differing amounts of whitespace).
* glcpp: Fix 064-version.c expected result to track recent change.Carl Worth2010-08-171-1/+0
| | | | | | In commit 6be3a8b70af4ba4fa4d037d54ecf6d5f055edbc9, the #version directive was fixed to stop generating a spurious newline. Here we simply update the expected result for the single test which includes a #version directive.

* glcpp: Fix "unterminated if" diagnostic.Carl Worth2010-08-111-0/+5
| | | | | | | | | | | This was previously being appended to the output string *after* a copy of the supposedly final string was made and handed to the caller. So the diagnostic was never actually visible to the user. We fix this by moving the check for an unterminated #if from glcpp_parser_destroy to the calling function, preprocess. This fixes the test case 083-unterminated-if.c.
* glcpp: Add an explicit diagnostic for #if with no expression.Carl Worth2010-08-111-1/+4

* glcpp: Reword diagnostic for #elif with no expressionCarl Worth2010-08-111-1/+0
| | | | | | Rather than telling the user what to fix, the standard convention is to describe what the detected problem is. With this change, test 081-elif-without-expression now passes.
