068bda492c implement DynamicJump for Arm 
which is in fact the same as return (moving address into pc)

ce79617875 fix the exit sequence 
was returning wrong register (1, not 0)
also saving the message for test, which changes order as the return value destroys the message

5f7683efcf pass return integer back out through exit 
for testing of binaries later (and off course general correctness)
Some tests were using the fact that the interpreter was used, changed those to return ints rather than strings

db459fcd3d fix label loading in arm 
was still loading the integer address
instead of the return address's address

046617f8dc add branch listener functionaliy 
have to store the branches and loop again as labels
dont neccessarily have positions yet

3298651238 split create_binary into two phases 
Which gives instructions a chance to check everything
and in Arms case check the constant loads/ instruction adding
So that during assembly no more change happens (and we don't have to reassemble)

7543236f4f objects didn't get positions 
positions.empty? was wrong check

698c845297 seperate position create and register 
many test fixes

9c93b38b8f crete positions while collecting objects 
clear two phase lifecycle for positions
always created invalid and set later
new does not auto add to cache
but create and get_or_create do
 2018-06-15 21:54:21 +03:00

2c765c8f14 rename the objects accessor 
and move to object keys, not object_id
 2018-06-15 09:18:39 +03:00

3cc9175efa start BranchListener 
but on hold, since it needs positions before we have them
Must create them during collection phase

5ec235d049 fixes outstanding misc, All green 
Well. it's been a while, positioning is fixed (again)
apart from the upcoming BranchListener

e1683938ed fix label positioning bug 
where a label at the end of a binary code resulted in the
label actually taking up a position, instead of sharing it with it's next

0513cd504f update return address in label 
so return jumps go to the right address

c7ad1d98ca introduce the LabeListener to move instructions along when first code position changes 2018-06-09 22:13:43 +03:00
Torsten Ruger
ec1d38f5a6 reimplement instruction listeners with indexes 
easier to understand, as indexes map to Binarycode indexes, and can thus later be used to assemble directoy into the  code
Almost no change in tests (now only multiples of 4 addresses allowed)

ad3040a846 add position_chaning to event interface 
by reacting to the change _before it happens, we can move any BinaryCode out of the way

So when Instruction are inserted and code gets inserted, we don't need to set up the correct listener explicitly (which is tricky across mathods and changing chains), but instead just move anything that is in the way along

5815d32bde make the instructions jump over the BinaryCode end 2018-06-07 19:27:44 +03:00
Torsten Ruger
2d218bbc48 work on jump insertion continues 
Now registering CodeListener instead of PositionListener
Also instead of on the previous, in itself, which is simpler
and allows to react to insertion at end

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

0e155315aa movs is not allowed into pc 
Illegal instruction it says
Otherwise the status update is nice (for branches) and we’ll keep

67100a3ef8 write adjusted address 
and rename integer to address in label

e39e96f646 create return address as own class to hold return addresses 
to distinguish from integer, which does not need adjusting

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
