Hi All,
To gain a better understanding of how the D compiler works I am
trying to implement support for bit fields in structures. I have
modified the parser code to admit the following syntax (for now)...
struct A{
uint:8 a;
uint:5 b;
uint:* unused; //Takes up the remaining space.
//Raise an error when the computed size is zero.
}
You can see my changes here...https://github.com/SDX2000/dmd
I have been trying to work out a strategy for modifying the compiler
code generation for quite some time now but haven't been able to
make much headway in this direction.
I would appreciate any help at this point.
Regards,
Sandeep Datta.
