c2d450f779 fold position module and object position 
simpler that way, aslo code is moving to listners

3bc35c2275 rework binary code positioning setup 
dependency chain set up explicitly.
Next have to react to events correctly

46fbfb7101 adds the simple object dependency 
where the next object is dependent on the previous one
and just behind it, the padded_length away
 2018-05-31 20:41:04 +03:00

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
 2018-05-31 00:07:58 +03:00
Torsten Ruger
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
Torsten Ruger
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

01a2911483 using label int in interpreter 2018-05-30 11:49:29 +03:00

0dc89c772a get the label int to work consistently 
still need to use it in the return
 2018-05-30 10:54:18 +03:00

074ec34659 wip, fixed some label, need more fixing 2018-05-30 10:29:38 +03:00

c55b41afae sort objects by class before positioning 
since we don’t have pages yet, but want consistent layout
 2018-05-29 20:52:58 +03:00

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)

7847420d49 make ints compile time mutable 
to change the label value and use the allocated stubs

b81d9565de fix binary code offset when calling 
in other words, remember the arm pipeline being 8

4b34546c11 fixing the binary code indexes 
AGAIN, that third of all bugs, the off by one
 2018-05-28 18:20:09 +03:00
Torsten Ruger
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
 2018-05-28 15:45:29 +03:00

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)
 2018-05-28 15:09:59 +03:00

6c06f61ab8 start on fake memory 
get index checks on the array access of parfait

be1bc63ff2 jump was written off the end of binary code, fixed 2018-05-28 11:45:04 +03:00

1c09d4202f fix all test 
and thus all green, two weeks of side branch positioning  done
(luckily not on arm, but interpreter)
 2018-05-25 20:40:39 +03:00

c0cd1e0740 fix an issue where instruction was in wrong code 
embarrassingly used instance variable where it should have been local
 2018-05-25 19:16:13 +03:00

6f0fad0957 dragging the extra through resets 
as the binary the instruction is in may change when repositioning
 2018-05-25 19:04:48 +03:00

8d8cc4b016 more test fixing 
only one bug to go

183d4152d5 loading label must translate the labels too 
(psst: like arm translator already did. duh)
 2018-05-24 19:20:06 +03:00

dae8e88b7a recurring bug, don't save label positions 
labels are ethereal, no length, so they don’t get to occupy a position
 2018-05-24 16:26:56 +03:00

8d510c2e7e getting instruction repositioning right 
big bug hunt, involving complicated maths (%)
 2018-05-24 14:27:53 +03:00

0293320bb8 use a constant for the binary code offset 
where the instructions start
 2018-05-23 21:35:22 +03:00

8ca70a6835 Steamline objectPosition init 
check for resetting on the same position with different class, which
should not happen
Ie it’s ok for an object to push another object up,
but not for an instruction to land on code

f5d1090c39 no-ops really 2018-05-23 18:06:55 +03:00

a2e7d7c469 give interpreter a clock and pc 
where the pc, like in cpu’s is the memory position.
That is what the interpreter works on.
But for humans, the clock is a simpler way to count where the program
is at, no. of instructions executed

a7a62d53b2 use modified opal logger 
logger was having bizarre format errors
copied and simplified (to get on)
 2018-05-20 14:45:48 +03:00

15e4533a2f fix interpreter to use positions 
tick from one (simulated memory) position to the next
(not from one instruction to the next)
 2018-05-17 20:14:59 +03:00
Torsten Ruger
8966a50a8a getter by position 
extract and expand position testing
never return labels (that have the same position as their target)
 2018-05-17 20:13:33 +03:00
Torsten Ruger
37d62d298e assemble risc to it's position (not itself) 
So in the next step the interpreter can use positions as program counter
and would be much more like the real thing
 2018-05-17 09:49:01 +03:00
Torsten Ruger
49c4d170ce make the interpreter platform 
but still using the risc_instruction stream
