| | | | | | | | | | | | | | Everyone at the Khronos meeting was as surprised that GLSL didn't already support this as we were. Several vendors said they'd ship it, but there didn't seem to be enough interest to put in the effort to make it ARB or KHR. v2: Fix a couple typos and rename the spec file to EXT_shader_integer_mix.spec.

* glcpp: Fix post-decrement underflow in loop-control variableCarl Worth2013-06-031-1/+3
| | | | | | | | | | | | | This loop-control condition with a post-decrement operator would lead to an underflow of collapsed_newlines. This in turn would cause a subsequent execution of the loop to labor inordinately trying to return the loop-control variable to a value of 0 again. Fix this by dis-intertwining the test and the decrement. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=65112 Reviewed-by: Kenneth Graunke <[email protected]>

* glcpp: Rewrite line-continuation support to act globally.Carl Worth2013-01-111-66/+49
| | | | | | | | | | | | | | | | | | | Previously, we were only supporting line-continuation backslash characters within lines of pre-processor directives, (as per the specification). With OpenGL 4.2 and GLES3, line continuations are now supported anywhere within a shader. While changing this, also fix a bug where the preprocessor was ignoring line continuation characters when a line ended in multiple backslash characters. The new code is also more efficient than the old. Previously, we would perform a ralloc copy at each newline. We now perform copies only at each occurrence of a line-continuation.

* glcpp: Accept pointer to GL context rather than just the API versionCarl Worth2013-01-113-4/+17
| | | | | | | | | As the preprocessor becomes more sophisticated and gains more optional behavior, it's easiest to just pass the GL context pointer to it so that it can examine any fields there that it needs to (such as API version, or the state of any driconf options, etc.).

* glsl/preprocessor: Extract version directive processing into a function.Paul Berry2012-12-061-19/+30
| | | | | | | | | | | | | | | | | | | | | Version directive handling is going to have to be used within two parser rules, one for desktop-style version directives (e.g. "#version 130") and one for the new ES-style version directive (e.g. "#version 300 es"), so this patch moves it to a function that can be called from both rules. No functional change. [mattst88] v2: Use intmax_t instead of int for version argument. Would otherwise write garbage after #version since PRIiMAX was reading 64-bits instead of 32. [idr] v3: A later commit fixes the caller of _glcpp_parser_handle_version_declaration to pass the correct number of parameters. Fix it in the patch that changes the interface instead.

* 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]>
