From a884da8a06806d55fa83c8011bb17d6838583f9b Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Wed, 22 Jun 2011 11:58:25 +0100 Subject: exec.c: Fix calculation of code_gen_buffer_max_size When calculating the point at which we should not try to put another TB into the code gen buffer, we have to allow not just for OPC_MAX_SIZE but OPC_BUF_SIZE. This is because the target translate.c will only stop when an instruction has put it past the OPC_MAX_SIZE limit, so we have to include the MAX_OP_PER_INSTR margin which that final insn might have used.
