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

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

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

15e4533a2f fix interpreter to use positions
tick from one (simulated memory) position to the next
(not from one instruction to the next)

8966a50a8a getter by position
extract and expand position testing
never return labels (that have the same position as their target)

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

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)

1c52ab6b67 use hex for labels
idea was to be able to compare to positions
(but they are different positions)

dd2c2cb975 fix init jump bug
the label for the jump was not translated correctly
call needs to go through to_cpu to create single instance
on the way init order slightly changed

be3d125b82 implement smaller than comparison
which is NOT an operator in the risc sense
rather a minus and a check for sign
(which _could be more efficient in arm, with conditional execution)
