** --------------------------------------------
|
|
** Support for Arm64 in GGLAssembler JIT
|
|
** --------------------------------------------
|
|
**
|
|
** Approach
|
|
** - GGLAssembler and associated files are largely un-changed.
|
|
** - A translator class maps ArmAssemblerInterface calls to
|
|
** generate Arm64 instructions.
|
|
**
|
|
** ----------------------
|
|
** ArmToArm64Assembler
|
|
** ----------------------
|
|
**
|
|
** - Subclassed from ArmAssemblerInterface
|
|
**
|
|
** - Translates each ArmAssemblerInterface call to generate
|
|
** one or more Arm64 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 Arm64 instructions. These functions also log the instruction
|
|
** to LOG, if ARM64_ASM_DEBUG define is set to 1
|
|
**
|
|
** - Dumps machine code and eqvt assembly if "debug.pf.disasm" option is set
|
|
** It uses arm64_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 Arm64
|
|
**
|
|
** - 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.
|
|
**
|
|
** --------------------------------------------
|
|
** ArmToArm64Assembler unit test bench
|
|
** --------------------------------------------
|
|
**
|
|
** - Tests ArmToArm64Assembler 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.
|
|
**
|
|
** ----------------------
|
|
** Arm64 disassembler
|
|
** ----------------------
|
|
** - This disassembler disassembles only those machine codes which can be
|
|
** generated by ArmToArm64Assembler. 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.
|
|
**
|
|
** - ArmToArm64Assembler maps these functions to appropriate 64 bit
|
|
** functions.
|
|
**
|
|
** ----------------------
|
|
** GGLAssembler changes
|
|
** ----------------------
|
|
** - Since ArmToArm64Assembler can generate 4 Arm64 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.
|
|
