Compiler Design: Intermediate Code Generation Introduction

WitrynaThis is what a code generator does. Some compilers generate twice: they first generate code in some “intermediate language” like SIL, LLVM IR, HIR, MIR, CIL, etc. Then they do the “real” code generation into a target language that is directly runnable (or really close to it), like virtual machine code, assembly language, or machine ... Witryna6 mar 2024 · A flow graph is simply a directed graph. For the set of basic blocks, a flow graph shows the flow of control information. A control flow graph is used to depict how the program control is being parsed among the blocks.
