The main difference between load_global and load_global_constant is that the latter can be reordered arbitrarily. If the access being lowered is already tagged as being reorderable, then we can preserve that by using the load_global_constant intrinsics instead of load_global. This gives us more flexibility. On Intel, this lets us use the load_global_constant_uniform_block_intel intrinsic for doing convergent block loads in more cases. This nets us significant reductions in spill/fills: Borderlands 3 on Lunarlake sees spills/fills reduced by 53%. Alchemist sees a 13% reduction. Improves performance of Borderlands 3 DX12 on Intel Battlemage by around 44%. Improves Hogwarts Legacy by around 14%.
