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
|
||
|
|
OpAtomicCompSwap.
