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
Torsten Ruger
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)

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

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 (%)

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
 2018-05-23 18:05:22 +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
 2018-05-17 09:49:01 +03:00

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

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

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)

33ffcf1d88 move resolve_method code from word to mom 
rather make resolve an instruction.
Since it was coded in risc anyway, we not only save the setup and call
But also makes the mom instruction flow clearer
The method really came from not wanting to code it in risc, but with
the Builder, that is now surprisingly painless

9867234c38 move most code from method_compiler to builder 
rather use builder in two ways, than sometimes compiler and sometimes
builder
Also makes it possible to reuse builtin code in mom’s to_risc, as both
use builder. The builtin code by directly adding to compiler, the mom
code not.

279fdcc1e2 really translate risc - cpu/arm 
also labels.
Actual translation/assembly is much cleaner

3bd23cee28 also separate risc and cpu inits for the machine 
interpreter works on risc, but assembler off cpu

a50368c3aa assembler will need redoing somewhat 
with own data objects, we can assemble into them first
then write
may also store cpu instructions

55832315eb more fix for multilevel constant load 
was ignoring first level which is already the second for a constant
as the constant is the first load.
first interpreter test working but looking dodgy

c5ec532616 use common list for risc instruction 
strange that that was not done before as the code was clearly copied
when extracting it

aa79e41d1c rename register to risc 
seems to fit the layer much better as we really have a very reduced
instruction set
