[SystemZ] Don't lower ATOMIC_LOAD/STORE to LOAD/STORE (#75879) 2024-03-18T21:21:50+00:00 Jonas Paulsson paulson1@linux.ibm.com 2024-03-18T21:21:50+00:00 8b8e1adbdecd5f37ebcaa8d4fdf333962f7a0eb7 - Instead of lowering float/double ISD::ATOMIC_LOAD / ISD::ATOMIC_STORE nodes to regular LOAD/STORE nodes, make them legal and select those nodes properly instead. This avoids exposing them to the DAGCombiner. - AtomicExpand pass no longer casts float/double atomic load/stores to integer (FP128 is still casted).
