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

67100a3ef8 write adjusted address 
and rename integer to address in label
1k hurray

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

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

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

dae8e88b7a recurring bug, don't save label positions

8ca70a6835 Steamline objectPosition init 
check for resetting on the same position with different class, which

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

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

37d62d298e assemble risc to it's position (not itself)

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

ec31bde33a fix use of messagesetup 
which does setup for the method being called
not the one we’re in. duh

ee0a1ca823 renaming methods args and frame 
to arguments_type and frame_type, because that is what they are
In honour of setup bug, where the types of those types were loaded,
instead of just them types

c51fc67ba5 make interpreter tests less brittle 
by factoring __init code away
just counting main

b9f85f9d2e use instance_variable_set/get instead of eval 
opal doesn’t like eval anymore

52d389cdbf auto extend binary code 
final solution will need repositioning
 2018-04-03 15:07:36 +03:00
Torsten Ruger
30ca70e042 remove extra instruction and use next instead 
was messing with binary writing as the assumption of 1 word writes is
baked in

17b52d4e80 fix dynamic resolution 
was loading self, when it needs to load receiver
some more test (up to the resolve) start working
 2018-04-03 12:55:28 +03:00

c304ad67c6 load space twice in init , messagesetup overwrites first 
lots of interpreter test changes, brittle, must factor __initi out

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

9fafbe4e96 remove Kernel class for clarification 
since it was a class it was fake anyway
moved methods to object
 2018-04-02 17:06:31 +03:00

87eee0b66e add object method missing as sys exit 
functions get added twice and thus removed once
remove restriction for now

fb29fb6431 linked list of methods instead of list of methods 
api changes slightly, especially for each, but mostly sama sama

rework plus to make that easy
