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

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)
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

39902401b9 positioning code by setting first method code

2d901bf7b6 not wrapping the cpu initial jump anymore

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
2018-05-11 18:36:45 +03:00

bc1e29e4f6 seperate different Position classes into own files
also tests

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)
2018-05-01 19:20:16 +03:00

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

Torsten Ruger
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)
2018-04-19 22:41:40 +03:00

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

8c322329fb fix builtin methods according to last commit 2018-04-08 18:52:17 +03:00
Torsten Ruger
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.

22409c93ee remove >>, consistent use of <<
makes code easier to read, like assignments
does remind of Passengers
2018-04-06 22:40:58 +03:00
Torsten Ruger
c042dd9faa allow reverse syntax for >> (ie <<)
slot >> reg makes sense, being a slot_to_reg
but . . .
consistently use of << (as meaning assignment , =) also makes sense
allow both and let time tell which makes more sense

576ae9261d recode resolve method as assembler
definitely needs some refactoring
in fact i was hoping to code this in ruby (with compiler tweeks)
but there it is: goes through the linked list of methods of the type
and compares their name with self (method on word)
if not found ends in sys exit for now
