January 18, 2003 DLI operator overloading + goals | ||||
---|---|---|---|---|
| ||||
Hi all, in my playing with DLI I've noticed that operator overloading only work for eq() and add(). A bit of a look through machine-i386.cpp and a bit of a hack got me subtration working too - but only for class/struct op class/struct type expressions. I've also just found that I get an error with ... Mytest sub(int i) ... there is the error Error: incompatible types for ((t2) - (1)): 'Mytest' and 'int' Which is an error code in cast.cpp So I'm guessing that this is another feature that isn't quite ready for primetime yet (operator overloading was added late if I recal?) I think that this is a frontend problem in the cast.cpp file and a backend issue in machine-i386 - am I right here? My second question is about the goals of DLI - the README says that this is a first pass attempt to write a D backend in order to write an entire compiler for D in D?. From the little I know about compilers having a self hosting compiler is usually a good thing as it catches a lot of bugs. Also, how is the gcc backend project going? Cheers Brad |
