一、注册 在添加disassembler时,在llvm/lib/Target/XXX/Disassembler/XXXDisassembler.cpp中会通过 RegisterMCDisassembler()将该pass进行注册。 二、调用 (1)在XXXDisassembler.cpp中的getInstruction(...)函数重新定义了基类MCDisassembler中的纯虚函数virtual DecodeStatus getInstruction(...) const = 0;,然后在...
The disassembler transforms the LLVM bitcode to human readable LLVM assembly. llvm-link llvm-link, not surprisingly, links multiple LLVM modules into a single program. lli lliisthe LLVM interpreter, which can directly execute LLVM bitcode (although very slowly…). For architectures that support it...
CodeGen:常规代码生成算法的实现:instruction selection, scheduler, register allocation, and all analyses needed for them MC : 底层功能的实现,比如:the assembler (assembly parser), relaxation algorithm (disassembler), and specific object file idioms such as ELF, COFF, MachO, and so on. TableGen : 包...
(1) Disassembler/Cpu0Disassembler.cpp 在这个反汇编文件中,实现了 td 文件中所有反汇编函数引用的函数,即 DecoderMethod 关键字指定的函数,尤其是对应一些特殊操作数的反汇编,比如内存引用的反汇编,因为这种特殊操作数格式是我们自定义的 td 类来定义的,所以也需要指定其反汇编方法。
Assemblers and disassemblers MCInst故意是一个非常简单的表示。试图尽可能多地传递语义信息,只保留指令操作码和操作数列表(以及汇编程序诊断的源位置)。与LLVM IR一样,这是一种具有多种可能编码的内部表示。最明显的两个是程序集(如上所示)和二进制对象文件。
This model applies equally well to interpreters and JIT compilers. The Java Virtual Machine (JVM) is also an implementation of this model, which uses Java bytecode as the interface between the front end and optimizer. 11.1.1. Implications of this Design ...

The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and...
