2011-02-02glcpp: Raise error when modulus is zeroChad Versace
For example, this now raises an error: #define XXX 1 / 0 Fixes bug: https://bugs.freedesktop.org//show_bug.cgi?id=33507 Fixes Piglit test: spec/glsl-1.10/preprocessor/modulus-by-zero.vert NOTE: This is a candidate for the 7.9 and 7.10 branches.

2011-01-29Revert "glcpp: Demote "macro redefined" from an error to a warning"Carl Worth
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).
2011-01-28glcpp: Demote "macro redefined" from an error to a warningCarl Worth
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).

2011-01-10glcpp: Generate an error for division by zeroIan Romanick
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.

2011-01-10glcpp: Fix segfault when validating macro redefinitionsChad Versace
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.

2010-11-17glsl: Unconditionally define GL_FRAGMENT_PRECISION_HIGH in ES2 shaders.Kenneth Graunke
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.

2010-10-14glsl: Slightly change the semantic of _LinkedShadersIan Romanick
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.

2010-08-23glcpp: Make standalone preprocessor work with a tty as stdinCarl Worth
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).
2010-08-23glcpp: Fix test suite to avoid flagging failed tests as valgrind errors.Carl Worth
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.
2010-08-23glcpp: Fix segfault in standalone preprocessor for "file not found", etc.Carl Worth
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.
2010-08-23glcpp: Update generated glcpp-lex.c for the last two changes.Carl Worth
This fixes both "#line 0" and "#line XXX YYY" as described in the two most recent commits.
2010-08-23glcpp: Fix handling of "#line 0"Carl Worth
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.)
2010-08-23glcpp: Fix source numbers set with "#line LINE_NUMBER SOURCE_NUMBER"Carl Worth
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.
2010-08-23glcpp: Add new test for #line directive.Carl Worth
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 #
2010-08-23glcpp: Update README file (new specifications and fewer limitations).Carl Worth
The README file had grown a little bit stale. We've been using newer versions of both the GLSL and C99 specifications, so list those. Also, several of the documented known limitations have since been fixed, so remove those.
2010-08-23glcpp: Add test for the #error directive.Carl Worth
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).

2010-08-17glcpp: Add support for "redefined macro" error.Carl Worth
Carefully avoiding printing any error when the new definition matches the existing definition. This fixes the recently-added 088-redefine-macro-legitimate.c and 089-redefine-macro-error.c tests as well as glsparsertest/preprocess1 in piglit.
2010-08-17glcpp: Add two new tests for testing redefined macros.Carl Worth
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).

This is useful for debugging the preprocessor.
2010-08-17glcpp: Fix 064-version.c expected result to track recent change.Carl Worth
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.
