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...

(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。

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 ...
