AsmJit
Low-Latency Machine Code Generation
AArch64 Backend
AArch64 backend.
Emitters
- a64::Assembler - AArch64 assembler (must read, provides examples).
- a64::Builder - AArch64 builder.
- a64::Compiler - AArch64 compiler.
- a64::Emitter - AArch64 emitter (abstract).
Supported Instructions
- Emitters:
- a64::EmitterExplicitT - Provides all instructions that use explicit operands, provides also utility functions. The member functions provided are part of all AArch64 emitters.
- Instruction representation:
- a64::Inst::Id - instruction identifiers.
Register Operands
- arm::Reg - Base class of all AArch32/AArch64 registers.
Memory Operands
- arm::Mem - AArch32/AArch64 memory operand that provides support for all ARM addressing features including base, index, pre/post increment, and ARM-specific shift addressing and index extending.
Other
- arm::Shift - Shift operation and value.
- arm::Utils - Utilities that can help during code generation for AArch32 and AArch64.
