propagate instruction positions
...
still overlapping onto binaries, but a start

introduce some helper methods
2018-06-02 23:02:59 +03:00
c2d450f779
fold position module and object position
...
simpler that way, aslo code is moving to listners
2018-06-02 21:59:41 +03:00
24f6e30b54
start on redoing instruction positions
...
using insruction listeners (wip)
2018-06-02 21:20:15 +03:00
3bc35c2275
rework binary code positioning setup
...
dependency chain set up explicitly.
Next have to react to events correctly
2018-06-02 17:29:38 +03:00
91c7903848
start simple with code listner

positioning wip
2018-06-02 16:12:01 +03:00
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
2018-05-31 19:05:53 +03:00
2544bc5a85
move position module to folder
2018-05-31 19:01:10 +03:00

little event mechanism for changed positions

movs is not allowed into pc
...
Illegal instruction it says
Otherwise the status update is nice (for branches) and we’ll keep
2018-05-31 14:03:25 +03:00

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
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)
2018-05-30 14:55:17 +03:00
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
2018-05-30 12:54:40 +03:00

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

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
296617cbaf
set label integer to position
2018-05-29 20:30:02 +03:00
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)
2018-05-29 20:26:00 +03:00
7847420d49
make ints compile time mutable
...
to change the label value and use the allocated stubs
2018-05-29 17:03:55 +03:00

fix binary code offset when calling
...
in other words, remember the arm pipeline being 8
2018-05-29 17:03:20 +03:00

fixing the binary code indexes
...
AGAIN, that third of all bugs, the off by one
2018-05-28 18:20:09 +03:00
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
2018-05-28 14:46:26 +03:00
be1bc63ff2
jump was written off the end of binary code, fixed
2018-05-28 11:45:04 +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

trying to fix the darn jump over object header
2018-05-25 19:03:46 +03:00

more test fixing
...
only one bug to go
2018-05-24 21:20:56 +03:00

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
2018-05-23 21:34:49 +03:00
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
2018-05-23 18:05:22 +03:00
ef2dc932ad
use positions in interpreter
2018-05-20 15:52:13 +03:00
c0f10bb42b
fix opal error
2018-05-20 15:51:36 +03:00
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
a350325b6b
fix function call and simple call logic
...
Before creating DynamicJump, the FunctionCall got a register for a
possible jump address. Now that is handled by DynamicJump and
FunctionCall just needs the method, from which it determines the
binaryCode address
2018-05-19 12:21:20 +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
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
