I've added (or will add, depending on whether this gets to the list
before the CVS syncup does) a couple of new opcodes.
find_type(INT, STR) returns the integer identifier number for any
known PMC type. That means you can now do:
find_type I0, "PerlArray"
new P0, I0
instead of
new P0, .PerlArray
Not a big deal for builtin types, but it means that you don't have to
tell the assembler about every new PMC class that gets added to the
system. (At the moment you do need to add the new class to
global_setup.c still, but I'm working on fixing that so PMCs can be
dynamically loadable)
lookback(INT|NUM|STR|PMC, INT) looks back up the user stack for the
entry you asked for with $2 and puts it in $1. Types are checked, so
no sneaky putting a PMC pointer into a string register or anything.
If $2 is negative, it counts up from the bottom, with the bottommost
entry in the stack being -1.
