* glcpp: Remove trailing contexts from #if rules.Kenneth Graunke2011-03-031-6/+6

* glcpp: Rework lexer to use a SKIP state rather than REJECT.Kenneth Graunke2011-03-031-21/+16
| | | | | | | | | | | | | | | | | | | Previously, the rule deleted by this commit was matched every single time (being the longest match). If not skipping, it used REJECT to continue on to the actual correct rule. The flex manual advises against using REJECT where possible, as it is one of the most expensive lexer features. So using it on every match seems undesirable. Perhaps more importantly, it made it necessary for the #if directive rules to contain a look-ahead pattern to make them as long as the (now deleted) "skip the whole line" rule. This patch introduces an exclusive start state, SKIP, to avoid REJECTs. Each time the lexer is called, the code at the top of the rules section will run, implicitly switching the state to the correct one. Fixes piglit tests 16384-consecutive-chars.frag and 16385-consecutive-chars.frag.
* glcpp/tests: Update 063-comments.c.expected to match output.Kenneth Graunke2011-03-031-0/+7
| | | | | | | The expected result has been out of sync with what glcpp produces for some time; glcpp's actual result seems to be correct and is very close to GCC's cpp. Updating this will make it easier to catch regressions in upcoming commits.
* glsl: Remove unused glcpp/Makefile.am.Kenneth Graunke2011-03-021-44/+0
| | | | This is a remnant of when glsl2 lived in its own repository.

* glcpp: Raise error when modulus is zeroChad Versace2011-02-021-1/+6

* Revert "glcpp: Demote "macro redefined" from an error to a warning"Carl Worth2011-01-294-38/+15
| | | | | | | | 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 Worth2011-01-284-15/+38
| | | | | | | | | | 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.

| | | | | We almost always want to simply steal; we only need to copy when copying a token list (in which case we're already cloning stuff anyway).

* glcpp: Generate an error for division by zeroIan Romanick2011-01-101-1/+6
| | | | | | | | | | | | | | | | | | | | When GCC encounters a division by zero in a preprocessor directive, it generates an error. Since the GLSL spec says that the GLSL preprocessor behaves like the C preprocessor, we should generate that same error. It's worth noting that I cannot find any text in the C99 spec that says this should be an error. The only text that I can find is line 5 on page 82 (section 6.5.5 Multiplicative Opertors), which says, "The result of the / operator is the quotient from the division of the first operand by the second; the result of the % operator is the remainder. In both operations, if the value of the second operand is zero, the behavior is undefined." Fixes 093-divide-by-zero.c test and bugzilla #32831. NOTE: This is a candidate for the 7.9 and 7.10 branches.

* glcpp: Fix segfault when validating macro redefinitionsChad Versace2011-01-101-0/+21
| | | | | | | | In _token_list_equal_ignoring_space(token_list_t*, token_list_t*), add a guard that prevents dereferncing a null token list. This fixes test src/glsl/glcpp/tests/092-redefine-macro-error-2.c and Bugzilla #32695.

* glsl: Unconditionally define GL_FRAGMENT_PRECISION_HIGH in ES2 shaders.Kenneth Graunke2010-11-171-1/+6
| | | | | | | | | This is really supposed to be defined only if the driver supports highp in the fragment shader - but all of our current ES2 implementations do. So, just define it. In the future, we'll need to add a flag to gl_context and only define the macro if the flag is set. "Fixes" freedesktop.org bug #31673.

* glsl: Slightly change the semantic of _LinkedShadersIan Romanick2010-10-141-0/+8
| | | | | | | | | | | | | | | Previously _LinkedShaders was a compact array of the linked shaders for each shader stage. Now it is arranged such that each slot, indexed by the MESA_SHADER_* defines, refers to a specific shader stage. As a result, some slots will be NULL. This makes things a little more complex in the linker, but it simplifies things in other places. As a side effect _NumLinkedShaders is removed. NOTE: This may be a candidate for the 7.9 branch. If there are other patches that get backported to 7.9 that use _LinkedShader, this patch should be cherry picked also.

* glcpp: Make standalone preprocessor work with a tty as stdinCarl Worth2010-08-231-33/+49
| | | | | | | | | | | | Previously glcpp would silently abort if it couldn't fstat the file being read, (so it would work with stdin redirected from a file, but would not work with stdin as a tty). The stat was so that glcpp could allocate a buffer for the file content in a single call. We now use talloc_realloc instead, (even if the fstat is possible). This is theoretically less efficient, but quite irrelevant, (particularly because the standalone preprocessor is used only for testing).
* 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: Fix segfault in standalone preprocessor for "file not found", etc.Carl Worth2010-08-231-4/+17
| | | | | | | | This error message was missing so that the program would simply segfault if the provided filename could not be opened for some reason. While we're at it, we add explicit support for a filename of "-" to indicate input from stdin.
* glcpp: Update generated glcpp-lex.c for the last two changes.Carl Worth2010-08-231-191/+186
| | | | | This fixes both "#line 0" and "#line XXX YYY" as described in the two most recent commits.
* glcpp: Fix handling of "#line 0"Carl Worth2010-08-231-2/+3
| | | | | | | | | | | | | | | | The existing DECIMAL_INTEGER pattern is the correct thing to use when looking for a C decimal integer, (that is, a digit-sequence not starting with 0 which would instead be an octal integer). But for #line, we really want to accept any digit sequence, (including "0"), and always interpret it as a decimal constant. So we add a new DIGITS pattern for this case. This should fix the compilation failure noted in bug #28138 https://bugs.freedesktop.org/show_bug.cgi?id=28138 (Though the generated file will not be updated until the next commit.)
* glcpp: Fix source numbers set with "#line LINE_NUMBER SOURCE_NUMBER"Carl Worth2010-08-231-2/+7
| | | | | | | Previously, the YY_USER_ACTION was overwriting the yylloc->source value in every action, (after that value had been carefully set by the handling of the #line directive). Instead, we want to initialize it once in YY_USER_INIT and then not touch it at all in YY_USER_ACTION.
* 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 #
