39  * Update ITSTATE after normal execution of an IT block instruction.
136  * The following definitions and macros are used to build instruction
161  * instruction. A match is found when (instruction & mask) == value.
164  *	Instruction decoding jumps to parsing the new sub-table 'table'.
169  *	to complete decoding of the instruction.
172  *	The probes instruction handler is set to the value found by
174  *	will be used to simulate the instruction when the probe is hit.
178  *	The probes instruction handler is set to the value found by
180  *	will be used to emulate the instruction when the probe is hit. The
181  *	modified instruction (see below) is placed in the probes instruction
186  *	Instruction decoding fails with INSN_REJECTED
198  *	instruction being decoded, then 'simulation_handler' will be used
208  * least significant 5 nibbles of the instruction being decoded. The regs value
215  * This indicates an instruction is encoded like:
224  * match an instruction (through the mask/value test). Any invalid register then
225  * found in the instruction will cause decoding to fail with INSN_REJECTED. In
226  * the above example this would happen if bits 11..8 of the instruction were
241  * Decoding the instruction "AND R4, R5, R6, ASL R15" will be rejected because
244  * Decoding the instruction "AND R4, R5, R6, ASL R7" will be accepted and the
245  * instruction will be modified to "AND R0, R2, R3, ASL R1" and then placed into
246  * the kprobes instruction slot. This can then be called later by the handler
248  * the indicated slot in the action array), in order to simulate the instruction.
277 	 * another instruction form. This distiction only matters for test
