Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “You can observe in the code that a quantum circuit operation is being defined and a variable called numOnes.”

A block of code is set as follows:

#include "llvm/IR/IRPrintingPasses.h"
#include "llvm/IR/LegacyPassManager.h"
#include "llvm/Support/ToolOutputFile.h"

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

  switch (Kind) {
// Many more cases
  case m88k:           return "m88k";
  }

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: “For development on OS X, it is best to install Xcode from the Apple store.”
