Qin Jiajia 7835b525 2016-10-08T11:20:17 Reland "Add workaround for unused std140 and shared uniform blocks on MacOS" On some Mac drivers with shader version 4.1, they will treat unused std140 and shared uniform blocks' members as inactive. However, WebGL2.0 based on OpenGL ES3.0.4 requires all members of a named uniform block declared with a shared or std140 layout qualifier to be considered active. The uniform block itself is also considered active. This workaround is to reference all members of unused std140 and shared uniform blocks at the beginning of the vertex/fragment shader's main().

Martin Radev 70866b89 2016-07-22T15:27:42 Change grammar to support features from es31 The grammar has been changed so that ES31 grammar is followed more closely. The ES31 grammar is not fully supported, only functionality related to qualifier enumeration is added. The ParseContext is changed so that type qualifiers can be now joined together (i.e. like layout qualifiers). This will allow enumeration of multiple storage qualifiers (i.e. uniform readonly coherent) which is essential for support of ES31 features. Some of the error checks had to be moved closer to the root of the parse tree since some of the information about the expression might be missing. Unfortunately, as there is no explicit ordering imposed by the grammar, additional checks for proper order of qualifiers had to be added. I also included unit tests which test against malformed shaders.

Olli Etuaho f541f529 2015-10-13T12:21:01 Fix parsing integers larger than 0x7FFFFFFF Parsing should accept all values between 0 and 0xFFFFFFFF as specified in ESSL 3.00 section 4.1.3. When a signed literal is parsed, it's interpreted as if it specifies the bit pattern of a two's complement integer. For example, parsing "0xFFFFFFFF" results in -1. Decimal literals behave the same way, so for example parsing "3000000000" results in -1294967296. This change affects parsing of literals in ESSL 1.00 as well. In ESSL 3.00, an out-of-range integer literal now generates a compiler error. Unit tests are added based on examples in the ESSL 3.00 spec and one example in GLSL 4.5 spec that ESSL should match.

Jamie Madill 42bcf32e 2014-08-25T16:20:46 Refactor ShaderVariables to store fields in the base. Instead of only storing structure information in Varyings, Uniforms and Interface Block Fields, store it in the base class. Also only store base variable information for struct fields, instead of fully typed information. This works because stuff like interpolation type, invariance, and other properties are for the entire variable, not individual fields. Also add new fields for interface block instance name, varying invariance and structure name for all struct types.
