Description
The VK_KHR_shader_float16_int8 extension allows use of 16-bit
floating-point types and 8-bit integer types in shaders for arithmetic
operations.
It introduces two new optional features shaderFloat16 and
shaderInt8 which directly map to the Float16 and the Int8
SPIR-V capabilities.
The VK_KHR_shader_float16_int8 extension also specifies precision
requirements for half-precision floating-point SPIR-V operations.
This extension does not enable use of 8-bit integer types or 16-bit
floating-point types in any shader input and
output interfaces and therefore does not supersede the
VK_KHR_8bit_storage or VK_KHR_16bit_storage extensions.
Promotion to Vulkan 1.2
All functionality in this extension is included in core Vulkan 1.2, with the
KHR suffix omitted.
However, if Vulkan 1.2 is supported and this extension is not, both the
shaderFloat16 and shaderInt8 capabilities are optional.
The original type, enum and command names are still available as aliases of
the core functionality.
