so we can get rid of brittle risc folder tests
All of those tests rely on many many implementation details
should just test result through interpreter, no chain.
so many relied (implicitly( on some builtin function
after all can't do much in ruby without calling
Now all those dependencies are explicit
Small risc changes come because the macro version has a return label and unreachable label
was using exit, since raise is not implemented. This was ambiguous as all programs exit.
Using :died as special kernel code and bending it, and reporting it in interpreter.
opted to hack require to be getting on
need require for the test helper
and the files in lib/parfait
General require mechanism would still be ok, but require_ralative means implementing file source, which needs to be dragged around. I'll make an issue
Compiler now removes the module Parfait scope
and also the ::Parfait:: Scope in module names
Which means we can compile scoped code
and get unscoped code. for Parfait
Handy for tests too
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)
no debugging, just worked!
only about 10% slower, nice
also recording qemu-linux times, which are a lot faster(and double bonus, save the startup/syncing)
to make smaller binaries with larger integer heaps
also ran some benchmarks to see if it makes a difference
at least the binaries are smaller, calling also faster
Super is a statement, a send really.
Not an expression (as maybe in c++)
The actual implementation will be a bit tricky, like raise, a bit of stack walking, but not impossible. Still, later
When the lambda is passed as argument, it must be moved. This triggers the generation of a corresponding parfait object (as before, and as for other constants) but now also triggers the code build. The code being the constant as it were
Also some more name fixes from renames
The parser presents the whole call that defines the block as a block. And so does the Ruby layer, as we don't want to do processing in ast.
Just making it clearer, also Vool:: block will have to be renamed
Object is the first (obviously) Parfait object to parse and fully compile to binary.
No tests yet, but almost 500 lines of real world code with 17 methods, not bad
previous commit affected rather many test, as the implicit returns add extra instructions
Also added some explicit returns, so as not to test the return logic too much. return (ie return nl) is a knonwn 3 risc operation.
Parfait was depending on it, ie it created a dependency out of Parfait. But Parfiat needs to be self contained.
Moved 2 methods into parfait object, and resolved single call from text_writer to third.
Same same, just have to remembe to actually execute the condition if it is a send
Having send a possible expression, removes one tmp variable and associated move, for a little extra work.
Next return and assign (rest)
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.
After having over 600 failing tests at one point, this does feel good.
Even better, most of the risc/interpreter tests where i didn't change anything came gree without changing the tests. ie we have binary compatibility.
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)
start at Object get_interna_word
using the pattern to replace the whole risc method with a single mom instruction. Copying the original risc code into the instrucitons to_risc
also adding some very basic tests
