e1683938ed fix label positioning bug 
where a label at the end of a binary code resulted in the
label actually taking up a position, instead of sharing it with it's next

0513cd504f update return address in label 
so return jumps go to the right address

c7ad1d98ca introduce the LabeListener to move instructions along when first code position changes 2018-06-09 22:13:43 +03:00

ec1d38f5a6 reimplement instruction listeners with indexes 
easier to understand, as indexes map to Binarycode indexes, and can thus later be used to assemble directoy into the  code
Almost no change in tests (now only multiples of 4 addresses allowed)

ad3040a846 add position_chaning to event interface 
by reacting to the change _before it happens, we can move any BinaryCode out of the way

So when Instruction are inserted and code gets inserted, we don't need to set up the correct listener explicitly (which is tricky across mathods and changing chains), but instead just move anything that is in the way along

5815d32bde make the instructions jump over the BinaryCode end 2018-06-07 19:27:44 +03:00

2d218bbc48 work on jump insertion continues 
Now registering CodeListener instead of PositionListener
Also instead of on the previous, in itself, which is simpler
and allows to react to insertion at end

46fbfb7101 adds the simple object dependency 
where the next object is dependent on the previous one
and just behind it, the padded_length away

21a9c56ba9 change position event code to use util 
general purpose event fireing
can then be used for several event types

0e155315aa movs is not allowed into pc 
Illegal instruction it says
Otherwise the status update is nice (for branches) and we’ll keep

67100a3ef8 write adjusted address 
and rename integer to address in label
1k hurray

e39e96f646 create return address as own class to hold return addresses 
to distinguish from integer, which does not need adjusting
 2018-05-30 23:49:01 +03:00

e86ca5ae9d integer was wrong padded§ length 
or rather right (2 as should be and will be)
but currently we use next AND value + type means 3, rounded 4
because we can’t swap types at compile time (as is planned at runtime,
we use next OR value)

53107d3ef8 reducing the label's int for return 
placing the raw address in the register to jump to
puts the extra instruction at the risc level (not arm), thus changing a
lot of (brittle?) tests

c55b41afae sort objects by class before positioning 
since we don’t have pages yet, but want consistent layout

e94c9ea37b add failfast 
tired of waiting for the almost 1000 tests to run through, just to get
an error message

296617cbaf set label integer to position 2018-05-29 20:30:02 +03:00
Torsten Ruger
8322fca7b3 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)

8ef1a471a4 finally change List to derive from data object 
can’t derive from data16 as some lists are longer
have to get the delegation to work first

f9a89db10c use fake memory 
fix integer offset bug
(which only didn’t cause errors as fixnums are still an order too big
and the famous +1 error hit the empty space)
