fix the exit sequence
...
was returning wrong register (1, not 0)
also saving the message for test, which changes order as the return value destroys the message

write adjusted address

and rename integer to address in label
1k hurray

give labels an integer that will end up being the position at runtime
...
Since integers are first class objects, we need to use an integer object
as the return address. The actual address can not be stored in an
instance variable since it is not an object.
The address is unique to the label and never changes after positioning
(using the int is next up)

introduce load_data instruction
...
which just loads data to a register (used internally)
as opposed to integers, which are objects

have to translate the labels

and use binary as function call target
(because we don’t have the translated label)

really translate risc - cpu/arm

also labels.
Actual translation/assembly is much cleaner

return just gets the register (no more offset)

rename register to risc

seems to fit the layer much better as we really have a very reduced
instruction set

makes source and target clear
2016-12-25 18:05:39 +02:00

rename set_slot
...
set_slot was clear about the target, but not the source.
Better with reg_to_slot (and soon it’s inverse slot_to_reg)

use arm shift at runtime
...
arm indexes are in bytes (x4) at compile time
but at runtime we only have the array indexes, iw word indexes
arm has the nice barrel shifter to save us an extra instruction

putstring unfolds length

index 0 is the marker word , so like in some, all indexes 1 based
works :-)

use translator and remove passes

the only passes that were left were reg -> arm
those are almost completely one to one, so the idea of passes didn’t fit
