Hi all,
i'm thinking about steps allowing us to minimize type conversions and thus less
temporaries.
The things that came to my mind are:
1. Adding a switch in libjit to change the behavior in type conversions from C
style
(if original value is signed the value is sign extended and zero extended
otherwise) to IL style
where the target type is responsible for the type of value entension.
2. Adding new comparisions where we can explicitely say if it's a signed or
unsigned compare.
3. Maybe some arithmetic functions for explicitely signed or unsigned operation
are needed too but that would be the last step.
Any suggestions ?
Cheers,
Klaus
