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
now a variable has to be created before being used
thus it is save to develop contracts where a certain name
must exist in the scope
Maybe the syntax starts getting a bit weird, but at least the ! is a common symbol in ruby
rather make resolve an instruction.
Since it was coded in risc anyway, we not only save the setup and call
But also makes the mom instruction flow clearer
The method really came from not wanting to code it in risc, but with
the Builder, that is now surprisingly painless
