cpu-exec: fix cpu_exec_nocache
In icount mode cpu_exec_nocache function is used to execute part of the existing TB. At the end of cpu_exec_nocache newly created TB is deleted. Sometimes io_read function needs to recompile current TB and restart TB lookup and execution. After that tb_find_fast function finds old (bigger) TB again. This TB cannot be executed (because icount is not big enough) and cpu_exec_nocache is called again. Such a loop continues over and over. This patch deletes old TB and avoids finding it in the TB cache. Signed-off-by: Pavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
