+** --------------------------------------------
+** Support for Aarch64 in GGLAssembler JIT
+** --------------------------------------------
+**
+** Approach
+** - GGLAssembler and associated files are largely un-changed.
+** - A translator class maps ArmAssemblerInterface calls to
+**   generate AArch64 instructions.
+**
+** ----------------------
+** ArmToAarch64Assembler
+** ----------------------
+**
+** - Subclassed from ArmAssemblerInterface
+**
+** - Translates each ArmAssemblerInterface call to generate
+**   one or more Aarch64 instructions  as necessary.
+**
+** - Does not implement ArmAssemblerInterface portions unused by GGLAssembler
+**   It calls NOT_IMPLEMENTED() for such cases, which in turn logs
+**    a fatal message.
+**
+** - Uses A64_.. series of functions to generate instruction machine code
+**   for Aarch64 instructions. These functions also log the instruction
+**   to LOG, if AARCH64_ASM_DEBUG define is set to 1
+**
+** - Dumps machine code and eqvt assembly if "debug.pf.disasm" option is set
+**   It uses aarch64_disassemble to perform disassembly
+**
+** - Uses register 13 (SP in ARM), 15 (PC in ARM), 16, 17 for storing
+**   intermediate results. GGLAssembler does not use SP and PC as these
+**   registers are marked as reserved. The temporary registers are not
+**   saved/restored on stack as these are caller-saved registers in Aarch64
+**
+** - Uses CSEL instruction to support conditional execution. The result is
+**   stored in a temporary register and then copied to the target register
+**   if the condition is true.
+**
+** - In the case of conditional data transfer instructions, conditional
+**   branch is used to skip over instruction, if the condition is false
+**
+** - Wherever possible, immediate values are transferred to temporary
+**   register prior to processing. This simplifies overall implementation
+**   as instructions requiring immediate values are converted to
+**   move immediate instructions followed by register-register instruction.
+**
+** --------------------------------------------
+** ArmToAarch64Assembler unit test bench
+** --------------------------------------------
+**
+** - Tests ArmToAarch64Assembler interface for all the possible
+**   ways in which GGLAssembler uses ArmAssemblerInterface interface.
+**
+** - Uses test jacket (written in assembly) to set the registers,
+**   condition flags prior to calling generated instruction. It also
+**   copies registers and flags at the end of execution. Caller then
+**   checks if generated code performed correct operation based on
+**   output registers and flags.
+**
+** - Broadly contains three type of tests, (i) data operation tests
+**   (ii) data transfer tests and (iii) LDM/STM tests.
+**
+** ----------------------
+** Aarch64 disassembler
+** ----------------------
+** - This disassembler disassembles only those machine codes which can be
+**   generated by ArmToAarch64Assembler. It has a unit testbench which
+**   tests all the instructions supported by the disassembler.
+**
+** ------------------------------------------------------------------
+** ARMAssembler/ARMAssemblerInterface/ARMAssemblerProxy changes
+** ------------------------------------------------------------------
+**
+** - In existing code, addresses were being handled as 32 bit values at
+**   certain places.
+**
+** - Added a new set of functions for address load/store/manipulation.
+**   These are ADDR_LDR, ADDR_STR, ADDR_ADD, ADDR_SUB and they map to
+**   default 32 bit implementations in ARMAssemblerInterface.
+**
+** - ArmToAarch64Assembler maps these functions to appropriate 64 bit
+**   functions.
+**
+** ----------------------
+** GGLAssembler changes
+** ----------------------
+** - Since ArmToAarch64Assembler can generate 4 Aarch64 instructions for
+**   each call in worst case, the memory required is set to 4 times
+**   ARM memory
+**
+** - Address load/store/manipulation were changed to use new functions
+**   added in the ARMAssemblerInterface.
