# A dynamic call calls a method at runtime. This off course implies that we don't know the
|
||
|
|
# method at compile time and so must "find" it. Resolving, or finding the method, is a
|
||
|
|
# a seperate step though, and here we assume there is a Method instance in some variable
|
||
|
|
#
|
||
|
|
# The only argument given is the variable's name.
|
||
|
|
# The instruction thus load the variable, finds the jump address from it and jumps there
|
||
|
|
# (ie calls). Calls are after all just jumps with the intent to return. Return addresses
|
||
|
|
# are setup in the preamble.

|

|
||
|
|
# As a side note: All argument setup/handling is outside the scope of this Instruction
|
||
|
|
# and assumed to be done beforehand.
|
||
|
|
# Also, in an ideal world we would check that the variable actually holds a Method
|
||
|
|
# but at the momeent we just assume it.
