b9bdc55059
A good start on the macro idea
...
I call it macro because it lets you insert basically arbitrary risc code into the ruby level. The way it works:
Reserve namespace X
map any X.some_call to a Mom instruction
by the name SomeCall
which must take the same args in constructor as given
And obviously produce whatever risc it wants
Hoping to rewrite builtin around this idea (with the existing Mom builtn instructions)

Changing the call setup and return to be more efficient
...
Now we are using a statically linked list of messages. This will not work with procs, but that can be solved then.
Previous (wrong) thinking was that because of procs messages have to be allocated for every call. This was too slow, and not neccessary

Move vool block compilation into constant generation

Fixing tests for implicit return

previous commit affected rather many test, as the implicit returns add extra instructions

Fix calling unknown methods
...
Before, when the type was determined, it was assumed that the method can be resolved. But off course tis is not true, as methods may be defined later in the file.
Two solutions for that. One could (and should) define all methods and only then start to compile. Thus having the type safety.
Or (as now) make a dynamic call and let it fail at runtime.

Move builtin wholesale to Mom
...
Since Builtin generates risc, just like mom instructions, it was a design mistake to put builtin into risc in the first place. Now that borders are coming more into focus, it make much more sense to have the builtin in mom.
In fact the instructions should be moved out and a seperate invocation mechanism used , so functions can be parsed, not generated (wip)

slightly better messages for unsupported ruby
...
Very slightly unfortunately, just just enought to find the error.
Also testing what is unsupported, so it's documented.

start writing parfait witout the module
...
Parfait classes must be unscoped. Now we start parsing Parfait, it must be without the module.
Luckily module_eval makes this a breeze.
Also remove string interpolation that is not yet processed

finally creating less objects in the test
...
basic still #23 , now applied
Basic size of 20, interpreter gets 50 and the full set is 1024
Tests run more than twice as fast!!

and set page size from new argument
This closes #23 , though ripples will follow

also in the rx-file dependency
all travis and testing with 2.4+

Very basic cli to compile ruby files
...
Off course this is basically a cross compiler and the files
have to be transferred to an arm machine (and fixed as per note)

remove the old add_new_int and calls
...
last orrurences in syscalls replaced, 2 variants
- exit does not actually need the int
- all else, preallocate the int beforehand and in syscall assume the reg name (integer_tmp)
test missing

in integer and word mainly, replaced with allocate_int
(tests pending as syscalls are undone)

also lazy init boot_function, so that compilers can be added up
before going to translate, where the boot_compilers are used

Move booting to RubyXCompiler init
...
Also pass the source into the compile method.
This way compiler can be reused for subsequent compile.
Does remove some double boots, but no major time save

Arrays and Hashes have to resolve to object creation calls
Not to constants. In the future off course

change to_risc and builtin code according to last commit
...
Wherever space was loaded to get to the next_message
we now load the Message factory.
Otherwise much the same, only the attribute is next_object, not next_message
The binary is growing with 1k objects per factory, so i had to fix (hack) arm to handle bigger constants
close #14

let spce keep the messages in a factory #14
...
Like Integers and addresses before, messages are now in a factory
Factories keep allocated (uninitialised) objects, had to make init public to call it

expand constant load
...
slightly hacky, but in good tradition
previous implementation only worked until 16 significant bits, which is getting to little
this one just keeps adding more instructions to arrive at the constant by force
There are surely cleverer ways of doing this, ie by using the barrel shifter
A start on #15 , admittedly a hack

remove the last_object from chain
...
also tried to keep the first around as was done in space
partially to not have to add the consrtants seperately
didn't work, as chain gets broken
also this has to be redone anyway

start with #14 by implementing factory
...
page was maybe a too low level name
pages may be the unit of the syscall, but after that objects desolve (maybe later to be added on from different pages)
Factory has the job of handing out a new instance of a type
it keeps a freelist for that and a reserve
