static std::vector<llvm::Value *> calculateBoundsOffset	(	LLVM::ModuleTranslation &	moduleTranslation,

static

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))

We must calculate the initial pointer offset to pass across, this function performs this using bounds.

TODO/WARNING: This only supports Fortran's column major indexing currently as is noted in the note below and comments in the function, we must extend this function when we add a C++ frontend. 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++.

operand evaluated outside of the target region), based on their uses inside of the target region.

Loop bounds and steps are only optionally populated, if output vectors are provided.

static

Return the llvm::Value * corresponding to the privateVar that is being privatized.

It isn't always as simple as looking up moduleTranslation with privateVar. For instance, in case of an allocatable, the descriptor for the allocatable is privatized. This descriptor is mapped using an MapInfoOp. So, this function will return a pointer to the llvm::Value corresponding to the block argument for the mapped descriptor.

This is useful when an OpenMP region with entry block arguments is converted to LLVM. In this case the block arguments are (part of) of the OpenMP region's entry arguments and the operands are (part of) of the operands to the OpenMP op containing the region.

This functions assumes that the builder's insertion point is where the user wants the init regions to be inlined; i.e. it does not try to find a proper insertion location for the init regions.
