I introduced a notion of extended values in Obc expressions,
replacing the Epattern constructor. Patterns may now only
occur at their rightful place, on the left of an assignment.
This change allows to index global constant arrays.
The compiler still does not support unsafe functions that well. For example, putting an assert()/exit() in an automaton's state does not work correctly.
Created two new files:
- utilities/global/compiler_options.ml: contains
the options that can be set using the cli
- utilities/global/errors.ml: contains global
errors definition
Misc now only contains helper functions that have
nothing to do with the ast or the compiler.
