Syntax Analysis,of characters, but into something that reflects the structure of the text. This “something” is typically a data structure called the . of the text. As the name indicates, this is a tree structure. The leaves of this tree are the tokens found by the lexical analysis, and if the leaves are read from lclarify 发表于 2025-3-22 03:54:37

Intermediate-Code Generation,l have to be expressed as machine code that can run on the computer. This does not mean that we need to translate directly from the high-level abstract syntax to machine code. Many compilers use a medium-level language as a stepping-stone between the high-level language and the very low-level machin粗糙滥制 发表于 2025-3-22 17:06:41

Register Allocation,ables in the intermediate language one-to-one into registers in the machine language. Processors, however, do not have an unlimited number of registers, so we need . to handle this conflict. The purpose of register allocation is to map a large number of variables into a small(ish) number of registerChameleon 发表于 2025-3-23 02:15:12

Data-Flow Analysis and Optimisation,recipe: First, the code is analysed to find opportunities for applying a specific optimisation, and then the optimisation is applied in the instances that are found. The analysis that collects the information is called a .. As the name indicates, a data-flow analysis analyses flow of information thr
