# This implements the creation of new frame and message object
|
||
|
|
|
||
|
|
# Frames and Message are very similar apart from the class name
|
||
|
|
# - All existing instances are stored in the space for both
|
||
|
|
# - Size is currently 2, ie 16 words (TODO a little flexibility here would not hurt, but the mountain is big)
|
||
|
|
# - Unused instances for a linked list with their first instance variable. This is HARD coded to avoid any lookup
|
||
|
|
|
||
|
|
# Just as a reminder: a message object is created before a send and holds return address/message and arguemnts + self
|
||
|
|
# frames are created upon entering a method and hold local and temporary variables
|
||
|
|
# as a result one of each is created for every single method call. A LOT, so make it fast luke
|
||
|
|
# Note: this is off course the reason for stack based implementations that just increment a known pointer/register or
|
||
|
|
# something. But i think most programs are memory bound and a few extra instructions don't hurt.
|
||
|
|
# After all, we are buying a big prize:oo, otherwise known as sanity.
