e12ce78d 9769 * (1) if the condexec bits are not already zero then we write
0ecb72a5 9770 * zero back into the CPUARMState now. This avoids complications trying
e12ce78d
PM		 9771 * to do it at the end of the block. (For example if we don't do this
9772 * it's hard to identify whether we can safely skip writing condexec
9773 * at the end of the TB, which we definitely want to do for the case
9774 * where a TB doesn't do anything with the IT state at all.)
9775 * (2) if we are going to leave the TB then we call gen_set_condexec()
0ecb72a5 9776 * which will write the correct value into CPUARMState if zero is wrong.
e12ce78d
PM		 9777 * This is done both for leaving the TB at the end, and for leaving
9778 * it because of an exception we know will happen, which is done in
9779 * gen_exception_insn(). The latter is necessary because we need to
9780 * leave the TB with the PC/IT state just prior to execution of the
9781 * instruction which caused the exception.
9782 * (3) if we leave the TB unexpectedly (eg a data abort on a load)
0ecb72a5 9783 * then the CPUARMState will be wrong and we need to reset it.
e12ce78d
PM		 9784 * This is handled in the same way as restoration of the
9785 * PC in these situations: we will be called again with search_pc=1
9786 * and generate a mapping of the condexec bits for each PC in
e87b7cb0
SW		 9787 * gen_opc_condexec_bits[]. restore_state_to_opc() then uses
9788 * this to restore the condexec bits.
e12ce78d

9790 * Note that there are no instructions which can read the condexec
9791 * bits, and none which can write non-static values to them, so
0ecb72a5 9792 * we don't need to care about whether CPUARMState is correct in the
e12ce78d
PM		 9793 * middle of a TB.
