32def9f467 Rename GL_KHX_shader_explicit_arithmetic_types to GL_EXT_shader_explicit_arithmetic_types 2018-12-03 13:16:59 +01:00

4c9876b34c Add names for composite constants in SPIR-V 
Consider the following code:

    layout(constant_id=0) const int Y = 1;
    layout(constant_id=1) const int Z = 2;
    layout(constant_id=3) const int X = Y + Z;

Previously, it would produce SPIR-V decorations like this:

    Decorate 21(Y) SpecId 1
    Decorate 22 SpecId 3
    Decorate 33(Z) SpecId 0

This seems inaccurate, since the spec constant `X` that is dependent on
the two others did not get a name in the SPIR-V decorations. This behavior
may potentially negatively affect shader introspection capabilities.

This change alters the behavior to always add a name, which results in the code
above producing the following decorations:

    Decorate 21(Y) SpecId 1
    Decorate 22(X) SpecId 3
    Decorate 33(Z) SpecId 0

647fccaf2f AST: Fix shift conversions, which don't require matching types. 
The base and shift amount need to be integers, but not of the same type.
This fixes #1296 and replaces #1297.

ac3707921e Revert the commits that change OpArrayLength type and bumped the version number. 
Now, version 5.* is all connected to making the uint type, which doesn't quite work.
Generator versions 4 and 6 do not do this.

8ff43de891 Implement the extension GL_ARB_gpu_shader_int64 
- Add new keyword int64_t/uint64_t/i64vec/u64vec.
- Support 64-bit integer literals (dec/hex/oct).
- Support built-in operators for 64-bit integer type.
- Add implicit and explicit type conversion for 64-bit integer type.
- Add new built-in functions defined in this extension.
