PPT-Compiler Construction

Lecture 15 Introduction to Program Analysis Program Analysis auxiliary information hints proof steps types Can come from compiler or user Goal Automatically computes potentially useful information about the program. 6 billion construction equipment industry in India is expec ted to touch about 103 billion While the current size is just a fraction of the world market it has been growing between 1015 compared to the global growth of around 5 The industry has bee Compiling. Your . C, C++ . or Fortran program won’t work unless you compile it. The compiler will build your program as an executable file (typically in the current directory), which you can then invoke and run just like any other command. . Application Security. CSS 548. Dan Chock. What are some ways that compilers can affect application security. ?. Improving . Application Security. Checking for and preventing potential . vulnerabilities. -- Basic functions. Generally, an independent course, maybe plus one semester on implementation of a compiler.. High level language program .  program in assembly language or object code directly.
