Chapter 11

1. For example:

   Mach-O: MacOS and iOS

   a.out: Simplifier gcc output

   COFF: Older Unix executable format

   PEF: PowerPC BE/OS and MacOS classic

   There are plenty!

2. .text: Usually the section that holds the executable instructions.debug: Usually holds the debugging symbols.plt,.dynamic,.got: Sections that hold the necessary information for the linker to solve the external symbols (functions and data that come from external libraries). Reading about the linking mechanism in elf is a very good idea!

4. Let's start with the strange string. When you look into how strings are stored in memory, you think of them as a list of characters, one after the other, in the order of growing memory addresses. This seems logical since you access them by incrementing a pointer. The thing is that the endianness (the direction a CPU stores numbers in its registers) can actually matter. What if I told you to break the string into blocks of four characters and read them in reverse?
