Calculate Start and End points of memory access. Let's assume A is the first access and B is a memory access on N-th loop iteration. Then B is calcula

\brief Match if we have a specific specified value.

Return an existing SCEV if it exists, otherwise analyze the expression and create a new one.

Helper function to make it easier to build SetCC's if you just have an ISD::CondCode instead of an SDValue.

isSimple - Test if the given EVT is simple (as opposed to being extended).

Return the IR name of the pointer value.

isValueDependent - Determines whether this expression is value-dependent (C++ [temp.dep.constexpr]). For example, the array bound of "Chars" in the fo

slice(n) - Chop off the first N elements of the array.

\brief Determine sign of this APInt. This tests the high bit of this APInt to determine if it is set. \returns true if this APInt is negative, false

getCallingConv()/setCallingConv(CC) - These method get and set the calling convention of this function. The enum values for the known calling convent

Get the underlying, templated declaration.

getNumIncomingValues - Return the number of incoming edges

Return the size in bits of the specified type, for which isSCEVable must return true.

data - Return a pointer to the vector's buffer, even if empty().

If Type is a reference type (e.g., const int&), returns the type that the reference refers to ("const int"). Otherwise, returns the type itself. This

Returns true if RC is a sub-class of or equal to this class.

Is this x86_64? (disregarding specific ABI / programming model)

hasAttribute - Checks if an argument has a given attribute.

\brief Return the unique reference to the type for the specified type declaration.

Get the block node for the entry block in the given function.

Ensures that this buffer has at least as much capacity as described.

getFeatureBits - Get feature bits a CPU.

getOrInsertFunction - Look up the specified function in the module symbol table. If it does not exist, add a prototype for the function and return it

AddComment - Add a comment that can be emitted to the generated .s file if applicable as a QoI issue to make the output of the compiler more readable.

/ getSUnit - Return the SUnit to which this edge points.
