Detailed Description

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.

Note that this can return a ConstantAggregateZero object.

getFP() constructors - Return a constant of vector type with a float element type taken from argument ‘ElementType’, and count taken from argument ‘Elts’.

The amount of bits of the contained type must match the number of bits of the type contained in the passed in ArrayRef. (i.e. half or bfloat for 16bits, float for 32bits, double for 64bits) Note that this can return a ConstantAggregateZero object.

getRaw() constructor - Return a constant with vector type with an element count and element type matching the NumElements and ElementTy parameters passed in.

Note that this can return a ConstantAggregateZero object. ElementTy must be one of i8/i16/i32/i64/half/bfloat/float/double. Data is the buffer containing the elements. Be careful to make sure Data uses the right endianness, the buffer will be used as-is.

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/half/bfloat/float/double) and must be a ConstantFP or ConstantInt.
