IrAtomicOp

enum Raven/Vixen.Raven/IR/IrInstruction.cs:81
csharp
public enum IrAtomicOp

What an atomic read-modify-write does to the value it finds.

No guide page documents this yet — the page shows what the code says about itself.

Remarks

Signedness is not here, because the place's type carries it: SPIR-V splits Min and Max into signed and unsigned opcodes and GLSL does not, so the split belongs to the backend that needs it rather than to an IR both read.
