* glcpp: Don't use alternation in the lookahead for empty pragmas.Carl Worth2014-08-221-2/+8
| | | | | | | | | | | | | | | | | | | | We've found that there's a buffer overrun bug in flex that's triggered by using alternation in a lookahead pattern. Fortunately, we don't need to match the exact {NEWLINE} expression to detect an empty pragma. It suffices to verify that there are no non-space characters before any newline character. So we can use a simple [\r\n] to get the desired behavior while avoiding the flex bug. Fixes the regression of piglit's 17000-consecutive-chars-identifier test, (which has been crashing since commit 04e40fd337a244ee77ef9553985e9398ff0344af ).

* glcpp: Fix glcpp-test-cr-lf "make check" test for Mac OS XCarl Worth2014-08-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | There were two problems with the way this script used sed on OS X: 1. The OS X sed doesn't interpret "\r" in a replacement list as a carriage-return character, (instead it was inserting a literal 'r' character). We fix this by putting an actual ^M character into the source of the script, (rather than a two-character escape sequence hoping for sed to do the right thing). 2. When generating the test files with LF-CR ("\n\r") newlines, the OS X sed was adding an undesired final newline ("\n") at the end of the file. We avoid this by first using sed to add the ^M before the newlines, then using tr to swap the \r and \n characters. This way, sed never sees any lines ending with anything but \n, so it doesn't get confused and doesn't add any bogus extra newlines.

* glsl/glcpp: Fix handling of commas that result from macro expansionCarl Worth2014-08-073-12/+45
| | | | | | | | | | | | | | | | | | | | | | | | Here is some additional stress testing of nested macros where the expansion of macros involves commas, (and whether those commas are interpreted as argument separators or not in subsequent function-like macro calls). Credit to the GCC documentation that directed my attention toward this issue: https://gcc.gnu.org/onlinedocs/gcc-3.2/cpp/Argument-Prescan.html Fixing the bug required only removing code from glcpp. When first testing the details of expansions involving commas, I had come to the mistaken conclusion that an expanded comma should never be treated as an argument separator, (so had introduced the rather ugly COMMA_FINAL token to represent this). In fact, an expanded comma should be treated as a separator, (as tested here), and this treatment can be avoided by judicious use of parentheses (as also tested here). With this simple removal of the COMMA_FINAL token, the behavior of glcpp matches that of gcc's preprocessor for all of these hairy cases. Reviewed-by: Ian Romanick <[email protected]>

* glsl/glcpp: Fix glcpp-test to correctly extract test-specific argumentsCarl Worth2014-08-071-1/+1
| | | | | | | | | | | | | | | | | | | | | The (optional) test-specific command-line arguments to be passed to glcpp are embedded within the source files of some tests, and glcpp-test uses grep to extract them. Of course, grep is line-based and looks for the native line-separator to determine line boundaries. So, for files using non-native line separators, grep was getting quite confused and passing bogus arguments to glcpp. Fix this by canonical-izing the line separators in the source file prior to using grep. With this commit, the glcpp-test-cr-lf tests pass entirely: \r: 143/143 tests pass \r\n: 143/143 tests pass \n\r: 143/143 tests pass Reviewed-by: Ian Romanick <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | Sometimes the newline separator is a single character, and sometimes it is two characters. Before we can fold away and line-continuation backslashes, we identify the flavor of line separator that is in use. With this identified, we then correctly search for backslashes followed immediately by the first character of the line separator. Also, when re-inserting newlines to replace collapsed newlines, we carefully insert newlines of the same flavor. With this commit, almost all remaining test are fixed as tested by glcpp-test-cr-lf: \r: 142/143 tests pass \r\n: 142/143 tests pass \n\r: 143/143 tests pass (The only remaining failures have nothing to do with the actual pre-processor code, but are due to a bug in the way the test suite uses grep to try to extract test-specific command-line options from the source files.)

* glsl/glcpp: Treat CR+LF pair as a single newlineCarl Worth2014-08-072-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GLSL specification says that either carriage-return, line-feed, or both together can be used to terminate lines. Further, it says that when used together, the pair of terminators shall be interpreted as a single line. This final requirement has not been respected by glcpp up until now, (it has been emitting two newlines for every CR+LF pair). Here, we fix the lexer by using a regular expression for NEWLINE that eats up both "\r\n" (or even "\n\r") if possible before also considering a single '\n' or a single '\r' as a line terminator. Before this commit, the test results are as follows: \r: 135/143 tests pass \r\n: 4/143 tests pass \n\r: 4/143 tests pass After this commit, the test results are as follows: \r: 135/143 tests pass \r\n: 140/143 tests pass \n\r: 139/143 tests pass So, obviously, a dramatic improvement.

* glsl/glcpp: Add test script for testing various line-termination charactersCarl Worth2014-08-072-11/+137
| | | | | | | | | | | | | | | | | | | | | | The GLSL specification has a very broad definition of what is a newline. Namely, it can be the carriage-return character, '\r', the newline character, '\n', or any combination of the two, (though in combination, the two are treated as a single newline). Here, we add a new test-runner, glcpp-test-cr-lf, that, for each possible line-termination combination, runs through the existing test suite with all source files modified to use those line-termination characters. Instead of using the .expected files for this, this script assumes that the regular test suite has been run already and expects the output to match the .out files. This avoids getting 4 test failures for any one bug, and instead will hopefully only report bugs actually related to the line-termination characters. The new testing is not yet integrated into "make check". For that, some munging of the testdir option will be necessary, (to support "make check" with out-of-tree builds). For now, the scripts can just be run directly by hand. Reviewed-by: Ian Romanick <[email protected]>
* glsl/glcpp: Fix for macros that expand to include "defined" operatorsCarl Worth2014-08-073-45/+387
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this commit, the following snippet would trigger an error in glcpp: #define FOO defined BAR #if FOO #endif The problem was that support for the "defined" operator was implemented within the grammar, (where the parser was parsing the tokens of the condition itself). But what is required is to interpret the "defined" operator that results after macro expansion is performed. I could not find any fix for this case by modifying the grammar alone. The difficulty is that outside of the grammar we already have a recursive function that performs macro expansion (_glcpp_parser_expand_token_list) and that function itself must be augmented to be made aware of the semantics of the "defined" operator. The reason we can't simply handle "defined" outside of the recursive expansion function is that not only must we scan for any "defined" operators in the original condition (before any macro expansion occurs); but at each level of the recursive expansion, we must again scan the list of tokens resulting from expansion and handle "defined" before entering the next level of recursion to further expand macros. And of course, all of this is context dependent. The evaluation of "defined" operators must only happen when we are handling preprocessor conditionals, (#if and #elif) and not when performing any other expansion, (such as in the main body). To implement this, we add a new "mode" parameter to all of the expansion functions to specify whether resulting DEFINED tokens should be evaluated or ignored. One side benefit of this change is that an ugly wart in the grammar is removed. We previously had "conditional_token" and "conditional_tokens" productions that were basically copies of "pp_token" and "pp_tokens" but with added productions for the various forms of DEFINED operators. With the new code here, those ugly copy-and-paste productions are eliminated from the grammar. A new "make check" test is added to stress-test the code here.

Add a production for the error case, (DEFINE_TOKEN followed immediately by a NEWLINE token). 3. Make the lexer reset to the <INITIAL> state after every NEWLINE. This 3rd point prevents the lexer from getting so confused and generating further spurious errors in the file because it was stuck in the <DEFINE> start condition.

Valgrind massif results for a trimmed apitrace of dota2: n time(i) total(B) useful-heap(B) extra-heap(B) stacks(B) Before (32-bit): 59 40,642,425,451 76,337,968 69,720,886 6,617,082 0 After (32-bit): 46 40,661,487,174 75,116,800 68,854,065 6,262,735 0 Before (64-bit): 79 37,179,441,771 106,986,512 98,112,095 8,874,417 0 After (64-bit): 64 37,200,329,700 104,872,672 96,514,546 8,358,126 0 A real savings of 846KiB on 32-bit and 1.5MiB on 64-bit. v2: (by Kenneth Graunke) Just add the ir_function from the IR stream, rather than looking it up in the symbol table; they're now identical.

* glsl: Only create one ir_function for a given name.Kenneth Graunke2014-08-041-14/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Piglit's spec/glsl-1.10/linker/override-builtin-{const,uniform}-05 tests do the following: 1. Call abs(float) - a built-in function. 2. Create a user-defined replacement for abs(float). 3. Call abs(float) again - now the user function. At step 1, we created an ir_function which included the built-in signature, added it to the symbol table, and emitted it into the IR stream. Then, when processing the function definition at step 2, we'd see that there was already an ir_function. But, since there were no user-defined functions, we skipped over a bunch of code, and ended up creating a second one. This new ir_function shadowed the original in the symbol table, but both ended up in the IR stream. This results in an awkward situation where searching for an ir_function via the symbol table, a forward linked list walk, and a reverse linked list walk may return different ir_functions. This seems undesirable. This patch instead re-uses the existing ir_function, putting both built-in and user-defined signatures in the same one. The previous patch's additional filtering ensures everything continues working. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* glsl: Make it possible to ignore built-ins when matching signatures.Kenneth Graunke2014-08-048-16/+26
| | | | | | | | | | | | | | | | | | Historically, we've implemented the rules for overriding built-in functions by creating multiple ir_functions and relying on the symbol table to hide the one containing built-in functions. That works, but has a few drawbacks, so the next patch will change it. Instead, we'll have a single ir_function for a particular name, which will contain both built-in and user-defined signatures. Passing an extra parameter to matching_signature makes it easy to ignore built-ins when they're supposed to be hidden. I didn't add the parameter to exact_matching_signature since it wasn't necessary. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This code was attemping to align the base of the structure to the required alignment of the structure. However, it had two problems: 1. It was aligning the target structure member, not the base of the structure. 2. It was calculating the alignment based on the members previous to the target member instead of all the members of the structure.
