46fbfb7101 adds the simple object dependency
where the next object is dependent on the previous one
and just behind it, the padded_length away

21a9c56ba9 change position event code to use util
general purpose event fireing
can then be used for several event types

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

0dc89c772a get the label int to work consistently
still need to use it in the return
2018-05-30 10:54:18 +03:00

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)

1c09d4202f fix all test
and thus all green, two weeks of side branch positioning  done
(luckily not on arm, but interpreter)

183d4152d5 loading label must translate the labels too
(psst: like arm translator already did. duh)

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

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

8966a50a8a getter by position

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

there is a jump in binary)

bc1e29e4f6 seperate different Position classes into own files

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.
