| === Description |
| |
| This extension allows a shader to contain floating-point atomic operations |
| on buffer, workgroup, and image memory. |
| It also advertises the SPIR-V code:AtomicFloat32AddEXT and |
| code:AtomicFloat64AddEXT capabilities that allows atomic addition on |
| floating-points numbers. |
| The supported operations include code:OpAtomicFAddEXT, |
| code:OpAtomicExchange, code:OpAtomicLoad and code:OpAtomicStore. |
