A stack-based environment will result in a dangling reference when the procedure is exited if a local variable in a procedure can be returned to the caller The simplest example:

The memory of a typical computer: A register area; Addressable Random access memory (RAM): A code area; A data area. The code area is fixed prior to execution, and can be visualized as follows:

Why Compiler Writing machine language-numeric codes is time consuming and tedious

Assuming two bytes for integers, four bytes for addresses, one byte for character and eight bytes for double-precision floating point, we would have the following offset values:

第5章 1.文法 S->(T) T->T, (1)对(a,(a,a)的最左推导为: S=>(T)

RUN-Time Organization Compiler phase- Before writing a code generator, we must decide how to marshal the resources of the target machine (instructions, storage, and system software) in order to implement the source language. This is called run-time organization
