Prolog (Windows Embedded CE 6.0)

1/5/2010

A prolog has several immediately contiguous parts, with no intervening instructions.

Typically, a prolog segment contains separate sequences of instructions that perform the following tasks:

  • Allocate a stack frame.
  • Save incoming argument registers.
  • Set up the frame pointer, if one is to be established. The prolog copies the stack pointer to a designated register before the initial register saves; then it uses this value to compute the value of the frame pointer.
  • Save the link register with return address.
  • Allocate space for compiler-generated temporaries, local variables, and an argument build area.
  • Indicate the end of the prolog code.

Be sure your prolog code is succinct and only performs the necessary operations.
