Description

This extension enables use of the more expressive fast floating-point math flags in the SPV_KHR_float_controls2 extension. These flags give finer- grained control over which optimizations compilers may apply, potentially speeding up execution while retaining correct results.

The extension also adds control over the fast-math modes to the GLSL extended instruction set, making these operations more consistent with SPIR-V and allowing their use in situations where floating-point conformance is important.

Synopsis

Documentation

data PhysicalDeviceShaderFloatControls2FeaturesKHR Source #

VkPhysicalDeviceShaderFloatControls2FeaturesKHR - Structure describing shader float controls 2 features that can be supported by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceShaderFloatControls2FeaturesKHR structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceShaderFloatControls2FeaturesKHR can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.
