Examples

%state = low.resource<vm_state> {index = 0, source_type = i64} : reg<vm.i64>

%binding = low.resource<hal_binding> {index = 0, source_type = hal.buffer} : reg<amdgpu.sgpr x2>

%dynamic = low.resource<hal_binding> extent(%extent) {index = 0, source_type = hal.buffer} : reg<amdgpu.sgpr x2>

%swizzled = low.resource<hal_binding> {index = 1, source_type = hal.buffer, cache_swizzle_stride = 64} : reg<amdgpu.sgpr x2>

%fixed = low.resource<command_input> {index = 0, source_type = buffer} : reg<cmd.buffer>
