Intermediate CodeGeneration, Intermediate CodeCode, Intermediate
The ultimate goal of a compiler is to get programs written in a high-level language to run on a computer. This means that, eventually, the program will 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 hig...
The intermediate code generator will try to divide this expression into sub-expressions and then generate the corresponding code.r1 = c * d; r2 = b + r1; a = r2r being used as registers in the target program.A three-address code has at most three address locations to calculate the ...
We spend both Chapter 4 and Chapter 5 on the issues that arise in generation of ir for source-code constructs. Procedure calls are, at once, both a source of inefficiency in the final code and the fundamental glue that pieces together different source files into a complete program. Chapter ...

操作数栈(Operand Stack)也常称为操作栈,它是一个后入先出(Last In First Out,LIFO)栈。同局部变量表一样,操作数栈的最大深度也在编译的时候写入到 Code 属性的 max_stacks 数据项中。操作数栈的每一个元素可以是任意的Java 数据类型,包括long 和 double。32 位数据类型所占的栈容量为1,64位数据类型所占...
Program 17 Names and Scopes • The three-address code generated by the syntax- directed definitions shown on the previous slides is somewhat simplistic, because it assumes that the names of variables can be easily resolved by the back end in global or local variables ...
Thus, the program is to be precisely compiled, assembled, loaded, linked and finally executed. The CPU and HW execute the lowest-level instruction sets, and the overall machine executes HLL instructions either sequentially or in parallel. When this mode of operation is projected to a set of ...
