Table 1-1. Register Terminology Conventions

Register Descriptive Name
Global Registers
Frame Pointer
Local Registers
Previous Frame Pointer
Stack Pointer
Return Instruction Pointer
Specific bits, flags and fields in registers and control words are usually referred to by a register
abbreviation (in upper case) followed by a bit, flag or field name (in lower case). These items are
separated with a period. A position number designates individual bits in a field. For example, the
return type (rt) field in the previous frame pointer (PFP) register is designated as "PFP.rt". The
least significant bit of the return type field is then designated as "PFP.rt0".
