/*
 * Opcode byteswap helpers
 *
 * These macros help with converting instructions between a canonical integer
 * format and in-memory representation, in an endianness-agnostic manner.
 *
 * __mem_to_opcode_*() convert from in-memory representation to canonical form.
 * __opcode_to_mem_*() convert from canonical form to in-memory representation.
 *
 *
 * Canonical instruction representation:
 *
 *	ARM:		0xKKLLMMNN
 *	Thumb 16-bit:	0x0000KKLL, where KK < 0xE8
 *	Thumb 32-bit:	0xKKLLMMNN, where KK >= 0xE8
 *
 * There is no way to distinguish an ARM instruction in canonical representation
 * from a Thumb instruction (just as these cannot be distinguished in memory).
 * Where this distinction is important, it needs to be tracked separately.
 *
 * Note that values in the range 0x0000E800..0xE7FFFFFF intentionally do not
 * represent any valid Thumb-2 instruction.  For this range,
 * __opcode_is_thumb32() and __opcode_is_thumb16() will both be false.
 *
 * The ___asm variants are intended only for use by this header, in situations
 * involving inline assembler.  For .S files, the normal __opcode_*() macros
 * should do the right thing.

/*
 * Opcode injection helpers
 *
 * In rare cases it is necessary to assemble an opcode which the
 * assembler does not support directly, or which would normally be
 * rejected because of the CFLAGS or AFLAGS used to build the affected
 * file.
 *
 * Before using these macros, consider carefully whether it is feasible
 * instead to change the build flags for your file, or whether it really
 * makes sense to support old assembler versions when building that
 * particular kernel feature.
 *
 * The macros defined here should only be used where there is no viable
 * alternative.
 *
 *
 * __inst_arm(x): emit the specified ARM opcode
 * __inst_thumb16(x): emit the specified 16-bit Thumb opcode
 * __inst_thumb32(x): emit the specified 32-bit Thumb opcode
 *
 * __inst_arm_thumb16(arm, thumb): emit either the specified arm or
 *	16-bit Thumb opcode, depending on whether an ARM or Thumb-2
 *	kernel is being built
 *
 * __inst_arm_thumb32(arm, thumb): emit either the specified arm or
 *	32-bit Thumb opcode, depending on whether an ARM or Thumb-2
 *	kernel is being built
 *
 *
 * Note that using these macros directly is poor practice.  Instead, you
 * should use them to define human-readable wrapper macros to encode the
 * instructions that you care about.  In code which might run on ARMv7 or
 * above, you can usually use the __inst_arm_thumb{16,32} macros to
 * specify the ARM and Thumb alternatives at the same time.  This ensures
 * that the correct opcode gets emitted depending on the instruction set
 * used for the kernel build.
 *
 * Look at opcodes-virt.h for an example of how to use these macros.
