The software stack.  Sorry, I guess I forgot to come right out and say that.
I have macros that manage a configurable software stack in STD.INS.ASPIC at
http://www.embedinc.com/pic.  The PUSHREGS and POPREGS macros push and pop
sets of general registers to/from the stack.  Higher level marcros like
GLBENT and LEAVEREST incorporate these to perform standard subroutine entry
and exit functions.
