Hi All,
now I'm successfully simulating the LargeIntegers plugin I'm hitting what I consider a bug in CArray, used to model C pointers in the simulator. The first problem is that CArray>>#+ & #- return an integer value, not another CArray, (in C (char *)(exp) + n is still of type (char *), not int) and that the addition/subtraction doesn't scale by the unit size (in C (type *)p + n == (type *)((char *)p + n * sizeof(type))). The second problem is that << >> * & // are meaningless on C pointers. Anyone think of a good reason why I shouldn't a) rewrite CArray>>#+ & #- to read
+ n ^ self shallowCopy += (n * unitSize)
- n ^ self shallowCopy -= (n * unitSize)
(since e.g. += increment
ptrOffset := ptrOffset + increment)
and b) delete CArray>>#*, #//, #<<, #>>, #bitAnd:, #bitOr:, #bitShift: & #signedBitShift: ?
