Since this is the only place this value is incremented, and we're under a lock, it should be cheaper to use
atomic_mb_set(&tcg_ctx.tb_ctx.tb_flush_count, tb_flush_req + 1);
+ uintptr_t tb_flush_req = (uintptr_t) + atomic_read(&tcg_ctx.tb_ctx.tb_flush_count);
Extra cast? That said, it's correct as-is so, Reviewed-by: Richard Henderson <r...@twiddle.net> r~
