Lecture 2, Jul 29, 2009

• In pdf
• LaTeX source. The figures were generated using dot2texi and pgf packages.
• In literate ``Haskell''

Sample code for

• sum.c The C program.
• sum.s Corresponding assembly code
• Disassmbled code from ./a.out. Each line has 3 portions. The left most portion is the address of the location, the middle portion is the machine code (in hexadecimal) and the last portion is the assembly code.

How to generate, compile and disassemble.

To compile

  $ gcc sum.c

To get the assembly code

  $ gcc -S sum.c

To disassemble the machine code

  $ objdumb --disassemble ./a.out | less
