class ConstantDataVector

Declaration

class ConstantDataVector : public ConstantDataSequential { /* full declaration omitted */ };

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.

Description

Methods for support type inquiry through isa, cast, and dyn_cast:

Declared at: llvm/include/llvm/IR/Constants.h:810

Parameters

const llvm::Value* V

¶static llvm::Constant* get(
    llvm::LLVMContext& Context,
    ArrayRef<uint8_t> Elts)

Description

get() constructors - Return a constant with vector type with an element count and element type matching the ArrayRef passed in. Note that this can return a ConstantAggregateZero object.

Declared at: llvm/include/llvm/IR/Constants.h:774

Parameters

llvm::LLVMContext& Context

¶static llvm::Constant* getSplat(
    unsigned int NumElts,
    llvm::Constant* Elt)

Description

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.

unsigned int NumElts

llvm::Constant* Elt

¶llvm::Constant* getSplatValue() const

¶inline llvm::VectorType* getType() const

Description

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

Declared at: llvm/include/llvm/IR/Constants.h:805

¶bool isSplat() const

Description

Returns true if this is a splat constant, meaning that all elements have the same value.
