◆ calculateBoundsOffset()

std::vector<llvm::Value *> calculateBoundsOffset ( LLVM::ModuleTranslation moduleTranslation,
llvm::IRBuilderBase &  builder,
bool  isArrayTy,
OperandRange  bounds 
)

This function calculates the array/pointer offset for map data provided with bounds operations, e.g.

when provided something like the following:

Fortran map(tofrom: array(2:5, 3:2)) or C++ map(tofrom: array[1:4][2:3]) We must calculate the initial pointer offset to pass across, this function performs this using bounds.

NOTE: which while specified in row-major order it currently needs to be flipped for Fortran's column order array allocation and access (as opposed to C++'s row-major, hence the backwards processing where order is important). This is likely important to keep in mind for the future when we incorporate a C++ frontend, both frontends will need to agree on the ordering of generated bounds operations (one may have to flip them) to make the below lowering frontend agnostic. The offload size calcualtion may also have to be adjusted for C++.
