Struct melior::dialect::ods::amdgpu::RawBufferAtomicFmaxOperation

pub struct RawBufferAtomicFmaxOperation<'c> { /* private fields */ }

A raw_buffer_atomic_fmax operation. Raw Buffer Floating-point Atomic Max (non-GFX9).

The amdgpu.raw_buffer_atomic_fmax op is a wrapper around the buffer-based atomic floating point max available on AMD GPUs (except GFX9).

The index into the buffer is computed as for memref.store with the addition of indexOffset (which is used to aid in emitting vectorized code) and, if present sgprOffset (which is added after bounds checks and includes any non-zero offset on the memref type).

All indexing components are given in terms of the memref’s element size, not the byte lengths required by the intrinsic.

Out of bounds atomic operations are ignored in hardware.

See amdgpu.raw_buffer_load for a description of how the underlying instruction is constructed.
