Sergey Fedorov 73c59faad5 tcg: Clean up direct block chaining safety checks ... We don't take care of direct jumps when address mapping changes. Thus we must be sure to generate direct jumps so that they always keep valid even if address mapping changes. Luckily, we can only allow to execute a TB if it was generated from the pages which match with current mapping. Document tcg_gen_goto_tb() declaration and note the reason for destination PC limitations. Some targets with variable length instructions allow TB to straddle a page boundary. However, we make sure that both of TB pages match the current address mapping when looking up TBs. So it is safe to do direct jumps into the both pages. Correct the checks for some of those targets. Given that, we can safely patch a TB which spans two pages. Remove the unnecessary check in cpu_exec() and allow such TBs to be patched.
