findBasePtr()

static Value * findBasePtr ( Value *  Val )

static

Find the base pointer of an array access.

This should be equivalent to ScalarEvolution::getPointerBase, which we cannot use here the IR is still under construction which ScalarEvolution assumes to not be modified.

getID()

static MDNode * getID ( LLVMContext &  Ctx, Metadata *  arg0 = nullptr, Metadata *  arg1 = nullptr  )

static

Get a self referencing id metadata node.

The MDNode looks like this (if arg0/arg1 are not null):

'!n = distinct !{!n, arg0, arg1}'

Returns

The self referencing id metadata node.

getMemAccInstPointerOperand()

static llvm::Value * getMemAccInstPointerOperand ( Instruction *  Inst )

static

Get the pointer operand.

Parameters

Inst	The instruction to be analyzed.

Returns

the pointer operand in case Inst is a memory access instruction and nullptr otherwise.
