*
* We want to avoid the overhead of having to write the updated condexec
* bits back to the CPUARMState for every instruction in an IT block. So:
* (1) if the condexec bits are not already zero then we write
* zero back into the CPUARMState now. This avoids complications trying
* to do it at the end of the block. (For example if we don't do this
* it's hard to identify whether we can safely skip writing condexec
* at the end of the TB, which we definitely want to do for the case
* where a TB doesn't do anything with the IT state at all.)
* (2) if we are going to leave the TB then we call gen_set_condexec()
* which will write the correct value into CPUARMState if zero is wrong.
* This is done both for leaving the TB at the end, and for leaving
* it because of an exception we know will happen, which is done in
* gen_exception_insn(). The latter is necessary because we need to
* leave the TB with the PC/IT state just prior to execution of the
* instruction which caused the exception.
* (3) if we leave the TB unexpectedly (eg a data abort on a load)
* then the CPUARMState will be wrong and we need to reset it.
* This is handled in the same way as restoration of the
* PC in these situations: we will be called again with search_pc=1
* and generate a mapping of the condexec bits for each PC in
* gen_opc_condexec_bits[]. restore_state_to_opc() then uses
* this to restore the condexec bits.
*
* Note that there are no instructions which can read the condexec
* bits, and none which can write non-static values to them, so
* we don't need to care about whether CPUARMState is correct in the
* middle of a TB.
