| | | | | | | | Splitting VAR and ASSIGN into IVAR, VAR, DEFINE and ASSIGN. This allows better handling by nuXmv for post-processing (since now only state variables are listed under VAR).

| | | | | | | Don't pad logical operands to one bit. Use operand width and signedness in $reduce_bool. Shift amounts are unsigned and shouldn't be padded. Group "is invalid" with the wire declaration, not its use (otherwise it is incorrectly wired to 0).

| * Consistent use of 'override' for virtual methods in derived classes.Henner Zeller2018-07-2015-36/+36
| | | | | | | | | | | | | | | | | | o Not all derived methods were marked 'override', but it is a great feature of C++11 that we should make use of. o While at it: touched header files got a -*- c++ -*- for emacs to provide support for that language. o use YS_OVERRIDE for all override keywords (though we should probably use the plain keyword going forward now that C++11 is established)
