This is more complicated. We map the MEMORY_*_LOGICAL opcodes to the older HDC messages: typed and untyped surface read/write/atomic (whether float or integer), DWord and Byte scattered messages, OWord block, and both A64, BTI, and stateless messages. - MEMORY_MODE_* is used to select stateless-scratch, typed, or untyped. - MEMORY_FLAG_TRANSPOSE is used to select block access. - MEMORY_BINDING_TYPE = FLAT and 64-bit address size selects A64. - Alignment and data type size select between byte/dword scattered or surface messages. While we may not be able to handle the full generality of message possibilities, we can handle everything we generate currently. The plan here is to assert/validate that we don't generate MEMORY_*_LOGICAL ops on HDC-based platforms which can't support those particular messages.
