Detailed Description

ConstantDataVector - A vector constant whose element type is a simple 1/2/4/8-byte integer or float/double, and whose elements are just simple data values (i.e. ConstantInt/ConstantFP). This Constant node has no operands because it stores all of the elements of the constant as densely packed data, instead of as Value*'s.

static

getSplat - Return a ConstantVector with the specified constant in each element. The specified constant has to be a of a compatible type (i8/i16/ i32/i64/float/double) and must be a ConstantFP or ConstantInt.

Constant * ConstantDataVector::getSplatValue ( ) const

getSplatValue - If this is a splat constant, meaning that all of the elements have the same value, return that value. Otherwise return NULL.

VectorType* llvm::ConstantDataVector::getType ( ) const

inline

getType - Specialize the getType() method to always return a VectorType, which reduces the amount of casting needed in parts of the compiler.
