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.

Promotion to Vulkan 1.4
Functionality in this extension is included in core Vulkan 1.4 with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
