moving to passing the instruction number, not the instruction
so in the error message we can say where the error is
(otherwise minitest is good enough to supress the trace of asserts calling asserts)
starting to implement register allocation by first creating SA
Single Assignment means a register is only every assigned a value once. Hence for any operation involving another register, a new register is created.
We do this with a naming scheme for the registers in dot notation (as it would be in c) which means 2 registers with the same name, should have the same contents. This does not apply to temporaries, but that is another day.
Starting WIP now, and will create many red commits before merging when green.
Simple is really the descriptive name for the layer
Sure, it is "virtual" but that is not as important as the fact that it is simple (or simplified)
Also objct (based really) is better, since orientated implies it is a little like that, but only orientated, not really it. Sol only has objects, nothing else
Just cause i was renaming anyway
both in mom and risc method complers
alll just compilers now, all linked
Required to move some code down into callable_compiler but all in all quite little. cleaner
args and locals got inlined into message, forgot to delete then
ripples out due to type creation
small type class api change, more ripples, but also more consistent
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
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.
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
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
