TODO: We should sort these to minimize wasted space due to alignment padding. Currently the padding is decided by the first encountered use during lowering.

Member Data Documentation

DynLDSAlign

Align llvm::AMDGPUMachineFunction::DynLDSAlign

protected

Align for dynamic shared memory if any.

Dynamic shared memory is allocated directly after the static one, i.e., LDSSize. Need to pad LDSSize to ensure that dynamic one is aligned accordingly. The maximal alignment is updated during IR translation or lowering stages.
