49849939a1 little event mechanism for changed positions 2018-05-31 17:01:23 +03:00

67100a3ef8 write adjusted address 
and rename integer to address in label
1k hurray
 2018-05-31 00:07:58 +03:00

e39e96f646 create return address as own class to hold return addresses 
to distinguish from integer, which does not need adjusting

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

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

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)

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)

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)

c0cd1e0740 fix an issue where instruction was in wrong code 
embarrassingly used instance variable where it should have been local

6f0fad0957 dragging the extra through resets 
as the binary the instruction is in may change when repositioning

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

8d510c2e7e getting instruction repositioning right 
big bug hunt, involving complicated maths (%)

0293320bb8 use a constant for the binary code offset 
where the instructions start

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

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

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

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

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

49c4d170ce make the interpreter platform 
but still using the risc_instruction stream
 2018-05-17 09:31:36 +03:00
Torsten Ruger
07ed16d765 groundwork for interpreter platform 
especially positioning makes the previous interpreter approach to
fragile (too far off the real thing)
Interpreter should be it’s own platform (still use the risc
instructions),
get a translator and use positions

39902401b9 positioning code by setting first method code 
codes will initial (and on reset) propagate the whole chain

2d901bf7b6 not wrapping the cpu initial jump anymore 
also introduce padding after cpu_init (wip)

776a97986d fix instruction positioning 
use at as at and only compute difference when needed (to determine if
there is a jump in binary)
Easier to understand that way

bc1e29e4f6 seperate different Position classes into own files 
also tests
and have Position module keep all positions
(singletons should be at module, not class level)

ce3cc72f9e move all position setting into position 
Position and subclasses handle the logic, external to
the classes, so it can be swapped out later
(at runtime positions can’t change)
