###3.1.1 Procedures

####3.1.1.1 Intel x86 stack frames

#####Values in stack frame:

• args
• eip(instruction pointer)
• ebp(caller’s frame pointer)
• saved registers
• local variables

#####Registers:

• eip instruction pointer

• esp stack pointer

• ebp frame pointer

• eax

  • register: return value of procedures
  • expected to be modified across calls, not saved in frame

####3.1.1.2 SPARC stack frames

###3.1.2 Threads and coroutines

thread control block: stores register states such as current value of the stack pointer

(Skip 3.1.3 & 3.1.4)
