More Experimental Ops

trap()

Break into debugger. Implementation notes:

 - x86/gcc ... works with gdb
 - ppc/gcc ... works with gdb, to proceed: gdb> p $pc = $pc + 4
 - TODO

For other architectures, this is a noop.

set_label(invar PMC, inconst LABEL)

Sets the opcode_t* label value for the given PMC. This is basically only useful for PMCs such as Sub, Continuation, ExceptionHandler and derivatives

get_label(out INT, invar PMC)

Gets the opcode_t* label value from the given PMC. This is basically only useful for PMCs such as Sub, Continuation, ExceptionHandler and derivatives

fetch(out PMC, in PMC, in PMC, in PMC)

Fetches a value from $2, keyed by $3 into $1. If the resulting PMC is PMCNULL, uses the type in $4 to create and return a new PMC.

fetch(out PMC, in PMC, in INT, in PMC)

fetch(out PMC, in PMC, in STR, in PMC)

vivify(out PMC, in PMC, in PMC, in PMC)

Fetches a value from $2, keyed by $3 into $1. If the resulting PMC is PMCNULL, uses the type in $4 to create and return a new PMC.

vivify(out PMC, in PMC, in INT, in PMC)

vivify(out PMC, in PMC, in STR, in PMC)
