Description
This extension advertises the SPIR-V Int64Atomics capability for Vulkan, which allows a shader to contain 64-bit atomic operations on signed and unsigned integers. The supported operations include OpAtomicMin, OpAtomicMax, OpAtomicAnd, OpAtomicOr, OpAtomicXor, OpAtomicAdd, OpAtomicExchange, and OpAtomicCompareExchange.
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, the
shaderBufferInt64Atomics capability is optional.
The original type, enum and command names are still available as aliases of
the core functionality.
