maxvujovic@gmail.com c6b3b3c7 2012-06-27T22:49:39 Fix the compiler warnings on WebKit ports when updating ANGLE in WebKit. Remove the varargs used for extra info formatting in the error() and warning() methods of ParseHelper. Use std::stringstream for formatting instead.

alokp@chromium.org 8b851c6d 2012-06-15T16:25:11 Preparation of hooking up the new preprocessor. - Added custom Diagnostics class. Routed all info-log messages via this new class. - Added custom DirectiveHandler class. Moved directive-handling code to this class and routed the old path. - Deleted lexer_glue because it is not needed anymore. The new preprocessor is almost ready! - Killed a bunch of dead code related to PragmaTable.

maxvujovic@gmail.com 66ebd014 2012-05-30T22:18:11 Add the SH_TIMING_RESTRICTIONS compile flag and dependency graph implementation. Description of the algorithm: http://code.google.com/p/mvujovic/wiki/ShaderControlFlowAnalysis This flag is one potential solution to timing attacks on textures containing cross-domain content or user agent data. This kind of analysis could be useful for both WebGL and CSS Shaders. The SH_TIMING_RESTRICTIONS flag will reject a shader if it uses texture dependent data to affect control flow. Other ways of affecting shader timing such as using NaNs in basic arithmetic operations or using built-in functions (e.g. atan) with different inputs are still under investigation. Issue=329 Review URL: http://codereview.appspot.com/6195062/ git-svn-id: https://angleproject.googlecode.com/svn/trunk@1101 736b8ea6-26fd-11df-bfd4-992fa37f6226
zmo@google.com f420c424 2011-09-12T18:27:59 Add/remove more functions to use shims. Remove normalize and add cos instead to avoid a crash in Mac with ATI cards (angle bug 193, 202). Also add atan and mod as it's also buggy on Mac/Win with NVIDIA cards. Also, trying to minimize emulated functions by adding masks for fragment/vertex shaders.

zmo@google.com e4eb9911 2011-08-29T21:13:12 Fix a bug introduced in r738. ANGLEBUG=201 TEST=chrome gpu bots green, no complaint from Firefox/Benoit Review URL: http://codereview.appspot.com/4956050 git-svn-id: https://angleproject.googlecode.com/svn/trunk@740 736b8ea6-26fd-11df-bfd4-992fa37f6226
zmo@google.com 32e97315 2011-08-24T01:03:11 Emulate certain buil-in functions to work around driver bugs. This is implemented by adding a new compile option SH_EMULATE_BUILT_IN_FUNCTIONS. The emulated functions are names as webgl_originalName_emu so there will never be naming conflicts. At the moment only three functions are emulated: normalize, abs, sign. Also, the compile option will emulate all three. However, the mechanism to emulate only a selected subset is also imeplemented. It can be turned on easily. ANGLEBUG=196 TEST=with this option, the failed test with abs.frag passes.

zmo@google.com fd747b86 2011-04-23T01:30:07 Implement shader identifier name mapping. The name mapping happens when an identifier is longer than 32 characters. The name mapping is behind a flag, so it won't happen by default. Also, functions to query the mapped names are added. The purpose of this CL is for the drivers that can't handle long names. For example, linux NVIDIA driver can't handle 256 character name, whereas WebGL spec requires that. This CL also fixes the issue that some of the TIntermSymbols' ids are 0s. ANGLEBUG=144 TEST=test manually with shaders with long identifier names.

zmo@google.com 0b8d4eb2 2011-04-04T19:17:11 Unroll for-loop if sampler array uses loop index as its index. If inside a for-loop, sampler array index is the loop index, Mac cg compiler will crash. This CL unroll the loop in such situation. The behavior is: 1) If the for-loop index is a float, we reject the shader. 2) If it is an integer, we unroll the for-loop. Things that should be done in the future are: 1) Add line number macros. 2) Add a limit to unroll iteration count. anglebug=94 Review URL: http://codereview.appspot.com/4331048 git-svn-id: https://angleproject.googlecode.com/svn/trunk@606 736b8ea6-26fd-11df-bfd4-992fa37f6226
apatrick@chromium.org 0f4cefe9 2011-01-26T19:30:57 Map D3D calls and HLSL shaders back to GLES2 calls and GLSL ES shaders in PIX. This makes debugging and profiling using PIX a lot more convenient. The top level of events are the GLES calls with their arguments. Those can be expanded to see the D3D calls that were issued for a particular GLES call. When PIX is attached, the shaders are saved out to temporary files and referenced from the translated HLSL shaders via #line directives. This enabled source level debugging of the original GLSL from PIX for pixel and vertex shaders. The HLSL is also saved to a temporary file so that intrinsic functions like texture2D can be stepped into. It also avoids creating a text file in the current working directory, which has continued to be an issue. I made the dependency on d3d9.dll static again so it can be accessed by GetModuleHandle witihin DllMain. I added an EVENT macro that issues D3DPERF_BeginEvent and D3DPERF_EndEvent around a C++ block. I replaced TRACE with EVENT for all the entry points. I removed the tracing of shader source since the source is visible in PIX. The means by which the filename of the temporary shader file is passed into the shader compiler is a little clunky. I did it that way to avoid changing the function signatures and breaking folks using the translator. I plan to make the compiler respect #pragma optimize so that optimization can be disabled for debugging purposes. For now it just disables shader optimization in debug builds of ANGLE.

alokp@chromium.org b59a778c 2010-11-24T18:38:33 Implemented validation for loop and indexing limitations specified by GLSL ES spec 1.0 Appendix A Section 4 and 5. A couple of things to note: - This CL only validates the "form" of loop and indexing. It does not detect number-of-iterations or out-of-bound access. This will require more involved analysis/heuristics. - I haved combined SH_VALIDATE_CONTROL_FLOW and SH_VALIDATE_INDEXING into one flag - SH_VALIDATE_LOOP_INDEXING. Validating both together is much easier. BUG=48 Review URL: http://codereview.appspot.com/3225041 git-svn-id: https://angleproject.googlecode.com/svn/trunk@491 736b8ea6-26fd-11df-bfd4-992fa37f6226
