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

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)

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

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

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

a7a62d53b2 use modified opal logger 
logger was having bizarre format errors
copied and simplified (to get on)

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

ab01fa3862 switch to 0 based indexing 
the world rocked for a moment (and more fixes to follow)
also the crumbling of idealism was heard

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

232fe67c09 introduce platform to abstract cpu and load address 2018-05-12 18:32:10 +03:00

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)
