+ update *INST to be in the form of the determined alias. */
+
+/* In the opcode description table, the following flags are used in opcode
+ entries to help establish the relations between the real and alias opcodes:
+
+ F_ALIAS: opcode is an alias
+ F_HAS_ALIAS: opcode has alias(es)
+ F_P1
+ F_P2
+ F_P3: Disassembly preference priority 1-3 (the larger the
+ higher). If nothing is specified, it is the priority
+ 0 by default, i.e. the lowest priority.
+
+ Although the relation between the machine and the alias instructions are not
+ explicitly described, it can be easily determined from the base opcode
+ values, masks and the flags F_ALIAS and F_HAS_ALIAS in their opcode
+ description entries:
+
+ The mask of an alias opcode must be equal to or a super-set (i.e. more
+ constrained) of that of the aliased opcode; so is the base opcode value.
+
+ if (opcode_has_alias (real) && alias_opcode_p (opcode)
+ && (opcode->mask & real->mask) == real->mask
+ && (real->mask & opcode->opcode) == (real->mask & real->opcode))
+ then OPCODE is an alias of, and only of, the REAL instruction
+
+ The alias relationship is forced flat-structured to keep related algorithm
+ simple; an opcode entry cannot be flagged with both F_ALIAS and F_HAS_ALIAS.
+
+ During the disassembling, the decoding decision tree (in
+ opcodes/aarch64-dis-2.c) always returns an machine instruction opcode entry;
+ if the decoding of such a machine instruction succeeds (and -Mno-aliases is
+ not specified), the disassembler will check whether there is any alias
+ instruction exists for this real instruction. If there is, the disassembler
+ will try to disassemble the 32-bit binary again using the alias's rule, or
+ try to convert the IR to the form of the alias. In the case of the multiple
+ aliases, the aliases are tried one by one from the highest priority
+ (currently the flag F_P3) to the lowest priority (no priority flag), and the
+ first succeeds first adopted.
+
+ You may ask why there is a need for the conversion of IR from one form to
+ another in handling certain aliases. This is because on one hand it avoids
+ adding more operand code to handle unusual encoding/decoding; on other
+ hand, during the disassembling, the conversion is an effective approach to
+ check the condition of an alias (as an alias may be adopted only if certain
+ conditions are met).
+
+ In order to speed up the alias opcode lookup, aarch64-gen has preprocessed
+ aarch64_opcode_table and generated aarch64_find_alias_opcode and
+ aarch64_find_next_alias_opcode (in opcodes/aarch64-dis-2.c) to help. */
