21  This extension advertises the SPIR-V *Int64Atomics* capability for Vulkan,
22  which allows a shader to contain 64-bit atomic operations on signed and
23  unsigned integers.
24  The supported operations include OpAtomicMin, OpAtomicMax, OpAtomicAnd,
25  OpAtomicOr, OpAtomicXor, OpAtomicAdd, OpAtomicExchange, and
26  OpAtomicCompareExchange.
