class ConstantDataSequential

Declaration

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

Description

ConstantDataSequential - A vector or array constant whose element type is a simple 1/2/4/8-byte integer or half/bfloat/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. This is the common base class of ConstantDataArray and ConstantDataVector.

Member Variables

private const char* DataElements

A pointer to the bytes underlying this constant (which is owned by the uniquing StringMap).

private std::unique_ptr<ConstantDataSequential> Next

This forms a link list of ConstantDataSequential nodes that have the same value but different type. For example, 0,0,0,1 could be a 4 element array of i8, or a 1-element array of i32. They'll both end up in the same StringMap bucket, linked up.

Methods

¶ConstantDataSequential(llvm::Type* ty,
                       llvm::Value::ValueTy VT,
                       const char* Data)

Declared at: llvm/include/llvm/IR/Constants.h:587

Parameters

llvm::Type* ty

llvm::Value::ValueTy VT

const char* Data

¶ConstantDataSequential(
    const llvm::ConstantDataSequential&)

Declared at: llvm/include/llvm/IR/Constants.h:593

Parameters

const llvm::ConstantDataSequential&

¶static bool classof(const llvm::Value* V)

Description

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

Declared at: llvm/include/llvm/IR/Constants.h:664

Parameters

const llvm::Value* V

¶void destroyConstantImpl()

Declared at: llvm/include/llvm/IR/Constants.h:584

¶llvm::StringRef getAsCString() const

Description

If this array is isCString(), then this method returns the array (without the trailing null byte) as a StringRef. Otherwise, it asserts out.

Declared at: llvm/include/llvm/IR/Constants.h:652

¶llvm::StringRef getAsString() const

Description

If this array is isString(), then this method returns the array as a StringRef. Otherwise, it asserts out.

Declared at: llvm/include/llvm/IR/Constants.h:645

¶llvm::APFloat getElementAsAPFloat(
    unsigned int i) const

Description

If this is a sequential container of floating point type, return the specified element as an APFloat.

Declared at: llvm/include/llvm/IR/Constants.h:611

Parameters

unsigned int i

¶llvm::APInt getElementAsAPInt(
    unsigned int i) const

Description

If this is a sequential container of integers (of any size), return the specified element as an APInt.

Declared at: llvm/include/llvm/IR/Constants.h:607

Parameters

unsigned int i

¶llvm::Constant* getElementAsConstant(
    unsigned int i) const

Description

Return a Constant for a specified index's element. Note that this has to compute a new constant to return, so it isn't as efficient as getElementAsInteger/Float/Double.

Declared at: llvm/include/llvm/IR/Constants.h:624

Parameters

unsigned int i

¶double getElementAsDouble(unsigned int i) const

Description

If this is an sequential container of doubles, return the specified element as a double.

Declared at: llvm/include/llvm/IR/Constants.h:619

Parameters

unsigned int i

¶float getElementAsFloat(unsigned int i) const

Description

If this is an sequential container of floats, return the specified element as a float.

Declared at: llvm/include/llvm/IR/Constants.h:615

Parameters

unsigned int i

¶uint64_t getElementAsInteger(unsigned int i) const

Description

If this is a sequential container of integers (of any size), return the specified element in the low bits of a uint64_t.

Declared at: llvm/include/llvm/IR/Constants.h:603

Parameters

unsigned int i

¶uint64_t getElementByteSize() const

Description

Return the size (in bytes) of each element in the array/vector. The size of the elements is known to be a multiple of one byte.

Declared at: llvm/include/llvm/IR/Constants.h:634

¶const char* getElementPointer(
    unsigned int Elt) const

Declared at: llvm/include/llvm/IR/Constants.h:670

Parameters

unsigned int Elt

¶llvm::Type* getElementType() const

Description

Return the element type of the array/vector.

Declared at: llvm/include/llvm/IR/Constants.h:627

¶static llvm::Constant* getImpl(
    llvm::StringRef Bytes,
    llvm::Type* Ty)

Declared at: llvm/include/llvm/IR/Constants.h:590

Parameters

llvm::StringRef Bytes

llvm::Type* Ty

¶unsigned int getNumElements() const

Description

Return the number of elements in the array or vector.

Declared at: llvm/include/llvm/IR/Constants.h:630

¶llvm::StringRef getRawDataValues() const

Description

Return the raw, underlying, bytes of this data. Note that this is an extremely tricky thing to work with, as it exposes the host endianness of the data elements.

Declared at: llvm/include/llvm/IR/Constants.h:661

¶bool isCString() const

Description

This method returns true if the array "isString", ends with a null byte, and does not contains any other null bytes.

Declared at: llvm/include/llvm/IR/Constants.h:641

¶static bool isElementTypeCompatible(
    llvm::Type* Ty)

Description

Return true if a ConstantDataSequential can be formed with a vector or array of the specified element type. ConstantDataArray only works with normal float and int types that are stored densely in memory, not with things like i42 or x86_f80.

Declared at: llvm/include/llvm/IR/Constants.h:599

Parameters

llvm::Type* Ty

¶bool isString(unsigned int CharSize = 8) const

Description

This method returns true if this is an array of \p CharSize integers.

Declared at: llvm/include/llvm/IR/Constants.h:637

Parameters

unsigned int CharSize = 8
