BP stands for Base Pointer / Frame Pointer.

Please, s/BP/FP/.  "Frame pointer" is an esablished name and several
assemblers use "fp" as a register name/alias (e.g. vax, sparc); "base
pointer" it too vague; clashes with "breakpoint".

Yes, FP is better alhough it clashes with Floating Point :-)


It does?

_REG_FP is defined by at least arm and vax.
