When the code fails, how helpful is the compiler’s feedback? (Think of the difference between a vague "Syntax Error" and the precise, color-coded suggestions provided by the Rust compiler). 3. Modern Tools and Trends

For those seeking "The Art of Compiler Design: Theory and Practice" in PDF form, several seminal texts define this field:

The compiler translates the AST into a "middle-man" code (like LLVM IR) that is easier to optimize.

How optimized is the resulting machine code?
