Book Description
It’s a critical lesson that today’s computer science students aren’t always being taught: How to carefully choose their high-level language statements to produce efficient code. Write Great Code, Volume 2: Thinking Low-Level, Writing High-Level shows software engineers what too many college and university courses don’t – how compilers translate high-level language statements and data structures into machine code. Armed with this knowledge, they will make informed choices concerning the use of those high-level structures and help the compiler produce far better machine code – all without having to give up the productivity and portability benefits of using a high-level language.

From the Back Cover
No prior knowledge of assembly language required!

In the beginning, most software was written in assembly, the CPU’s low-level language, in order to achieve acceptable performance on relatively slow hardware. Early programmers were sparing in their use of high-level language code, knowing that a high-level language compiler would generate crummy, low-level machine code for their software. Today, however, many programmers write in high-level languages like C, C++, Pascal, Java, or BASIC. The result is often sloppy, inefficient code. You don’t need to give up the productivity and portability of high-level languages in order to produce more efficient software.

In this second volume of the Write Great Code series, you’ll learn:

- How to analyze the output of a compiler to verify that your code does, indeed, generate good machine code
- The types of machine code statements that compilers typically generate for common control structures, so you can choose the best statements when writing HLL code
- Just enough 80×86 and PowerPC assembly language to read compiler output
- How compilers convert various constant and variable objects into machine data, and how to use these objects to write faster and shorter programs

With an understanding of how compilers work, you’ll be able to write source code that they can translate into elegant machine code. That understanding starts right here, with Write Great Code, Volume 2: Thinking Low-Level, Writing High-Level.
