Olli Etuaho a6996685 2015-10-12T14:32:30 Automatically enable highp in fragment shaders on ESSL3 Most code using the translator already enables highp with the resources flag when a shader spec that accepts ESSL3 is used, but for example the shader_translator utility doesn't. This fix makes sure that highp is always enabled when a fragment shader written in ESSL3 or newer is being compiled. This will make shader_translator easier to use for testing ESSL3 shaders.

Add an option to replace pow(x, y) with exp2(y * log2(x)) when y is a constant to work around this issue. This is done with an AST traverser instead of BuiltInFunctionEmulator, since there's no mechanism in BuiltInFunctionEmulator to apply the replacements only to calls where the second parameter is constant.

Olli Etuaho 853dc1ab 2014-11-06T17:25:48 Add mediump and lowp precision emulation support for GLSL output This implements the rounding as specified in WEBGL_debug_shader_precision extension proposal for desktop GLSL and ESSL output. The bulk of the new functionality is added in the form of a new EmulatePrecision AST traverser, which inserts calls to the rounding routines angle_frm and angle_frl in the appropriate places, and writes the rounding routines themselves to the shader. Compound assignments which are subject to emulation are transformed from "x op= y" to "angle_compound_op_frm(x, y)", a call to a function which does the appropriate rounding and places the result of the operation to x. The angle_ prefixed names should not clash with user-defined names if name hashing is on. If name hashing is not on, the precision emulation can only be used if the angle_ prefix is reserved for use by ANGLE. To support the rounding routines in output, a new operator type is added for internal helper function calls, which are not subject to name hashing. In ESSL output, all variables are forced to highp when precision emulation is on to ensure consistency with how precision emulation performs on desktop. Comprehensive tests for the added code generation are included.

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.

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 5601ea0d 2011-06-10T18:23:25 Implement ES2 backend for Angle translator. With this CL, we have the option to select a code output backend: GLSL, GLSL ES, or HLSL. Note that we always emit the highest supported float precision for fragment shader due to anglebug 168. Although this is a temporary solution, it's not against GLSL ES spec, because it's ok for implementation to upgrade precision. Tested with WebGL conformance test suite, GLES2 conformance test suite (only failed 2/1198), and a few webgl demos, including worlds of webgl, aquarium, etc. anglebug=81 test=translator emitting correct GLSL ES code when ES2 backend is selected.

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.

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
