ef247e75ec GLSL: Improve support for GL_ARB_shader_draw_parameters in desktop GLSL.
Opt-in to using the extension to support gl_InstanceIndex.

6a58554568 Support the SPV_KHR_device_group extension.
The only piece added by this extension is the `DeviceIndex` builtin,
which tells the shader which device in a grouped logical device it is
running on.

Metal's pipeline state objects are owned by the `MTLDevice` that created
them. Since Metal doesn't support logical grouping of devices the way
Vulkan does, we'll thus have to create a pipeline state for each device
in a grouped logical device. The upcoming peer group support in Metal 3
will not change this. For this reason, for Metal, the device index is
supplied as a constant at pipeline compile time.

There's an interaction between `VK_KHR_device_group` and
`VK_KHR_multiview` in the
`VK_PIPELINE_CREATE_VIEW_INDEX_FROM_DEVICE_INDEX_BIT`, which defines the
view index to be the same as the device index. The new
`view_index_from_device_index` MSL option supports this functionality.

2ed171e525 GLSL/MSL: Implement 8-bit part of VK_KHR_shader_float16_int8.
Storage was in place already, so mostly just dealing with bitcasts and
constants.

Simplies some of the bitcasting logic, and this exposed some bugs in the
implementation. Refactor to use correct width integers with explicit bitcast opcodes.

117ccf407c Use specific base types for 8- and 16-bit integers. 2018-11-01 17:45:10 -05:00

1fb27b4cda Add support for 8- and 16-bit types to GLSL and MSL.
In GLSL, 8-bit types require GL_EXT_shader_8bit_storage. 16-bit types
can use either GL_AMD_gpu_shader_int16/GL_AMD_gpu_shader_half_float or
GL_EXT_shader_16bit_storage.

e67f6f85a4 Defer parenthesis generation until needed.
Previously, we would generate parentheses proactively when generating
binary ops, however, this leads to uglier code and hits warnings in
compilers when used as a conditional.
