d4b5054d 2015-09-28 12:19:26 compiler: Rewrite do-while loops as while loops This works around a Mac driver shader compiler bug that makes many do-while loops cause GPU-hangs when ran.

217fe6ec 2015-08-05 13:25:08 Detect when built-in modf requires an l-value in AST traversal This fixes an omission that out parameter tracking had inherited from EmulatePrecision. Accurate tracking of when values are written is required for converting dynamic indexing of vectors and matrices to function calls. A new test covering this is added to angle_unittests.

05b6b7fc 2015-03-02 17:08:09 Add an SH_GLSL_CORE_OUTPUT profile. So we could generate shaders for Apple using core GL profile. By switching to core profile, we still pass most WebGL conformance tests 1.0.2 on Linux, but not all, so apparently more work is needed. However, I think it's OK to check this CL in because this output profile will be only used behind a chromium switch.

853dc1ab 2014-11-06 17:25:48 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.
