9238 *
9239 * We want to avoid the overhead of having to write the updated condexec
9240 * bits back to the CPUState for every instruction in an IT block. So:
9241 * (1) if the condexec bits are not already zero then we write
9242 * zero back into the CPUState now. This avoids complications trying
9243 * to do it at the end of the block. (For example if we don't do this
9244 * it's hard to identify whether we can safely skip writing condexec
9245 * at the end of the TB, which we definitely want to do for the case
9246 * where a TB doesn't do anything with the IT state at all.)
9247 * (2) if we are going to leave the TB then we call gen_set_condexec()
9248 * which will write the correct value into CPUState if zero is wrong.
9249 * This is done both for leaving the TB at the end, and for leaving
9250 * it because of an exception we know will happen, which is done in
9251 * gen_exception_insn(). The latter is necessary because we need to
9252 * leave the TB with the PC/IT state just prior to execution of the
9253 * instruction which caused the exception.
9254 * (3) if we leave the TB unexpectedly (eg a data abort on a load)
9255 * then the CPUState will be wrong and we need to reset it.
9256 * This is handled in the same way as restoration of the
9257 * PC in these situations: we will be called again with search_pc=1
9258 * and generate a mapping of the condexec bits for each PC in
9259 * gen_opc_condexec_bits[]. gen_pc_load[] then uses this to restore
9260 * the condexec bits.
9261 *
9262 * Note that there are no instructions which can read the condexec
9263 * bits, and none which can write non-static values to them, so
9264 * we don't need to care about whether CPUState is correct in the
9265 * middle of a TB.
