[PATCH 1/2] RISC-V: Let non-atomic targets use optimized amo loads/stores

2023-10-30 Thread Patrick O'Neill

Non-atomic targets are currently prevented from using the optimized fencing for seq_cst load/seq_cst store. This patch removes that constraint. gcc/ChangeLog: * config/riscv/sync-rvwmo.md (atomic_load_rvwmo): Remove TARGET_ATOMIC constraint (atomic_store_rvwmo): Ditto.
