class BitsInit

Declaration

class BitsInit : public TypedInit, public Node, public TrailingObjects { /* full declaration omitted */ };

Description

'{ a, b, c }' - Represents an initializer for a BitsRecTy value. It contains a vector of bits, whose size is determined by the type.

Methods

¶BitsInit(const llvm::BitsInit&)

Declared at: llvm/include/llvm/TableGen/Record.h:521

Parameters

const llvm::BitsInit&

¶void Profile(llvm::FoldingSetNodeID& ID) const

Declared at: llvm/include/llvm/TableGen/Record.h:533

Parameters

llvm::FoldingSetNodeID& ID

¶bool allInComplete() const

Declared at: llvm/include/llvm/TableGen/Record.h:546

¶static bool classof(const llvm::Init* I)

Declared at: llvm/include/llvm/TableGen/Record.h:527

Parameters

const llvm::Init* I

¶llvm::Init* convertInitializerBitRange(
    ArrayRef<unsigned int> Bits) const

Description

This method is used to implement the bitrange selection operator. Given an initializer, it selects the specified bits out, returning them as a new init of bits type. If it is not legal to use the bit subscript operator on this initializer, return null.

Declared at: llvm/include/llvm/TableGen/Record.h:538

Parameters

ArrayRef<unsigned int> Bits

¶llvm::Init* convertInitializerTo(
    llvm::RecTy* Ty) const

Description

Convert to an initializer whose type is-a Ty, or return nullptr if this is not possible (this can happen if the initializer's type is convertible to Ty, but there are unresolved references).

Declared at: llvm/include/llvm/TableGen/Record.h:537

Parameters

llvm::RecTy* Ty

¶static llvm::BitsInit* get(
    ArrayRef<llvm::Init*> Range)

Declared at: llvm/include/llvm/TableGen/Record.h:531

Parameters

ArrayRef<llvm::Init*> Range

¶std::string getAsString() const

Description

Convert this value to a string form.

Declared at: llvm/include/llvm/TableGen/Record.h:553

¶llvm::Init* getBit(unsigned int Bit) const

Description

This method is used to return the initializer for the specified bit.

Declared at: llvm/include/llvm/TableGen/Record.h:557

Parameters

unsigned int Bit

¶unsigned int getNumBits() const

Declared at: llvm/include/llvm/TableGen/Record.h:535

¶bool isComplete() const

Description

This virtual method should be overridden by values that may not be completely specified yet.

Declared at: llvm/include/llvm/TableGen/Record.h:540

¶bool isConcrete() const

Description

Is this a concrete and fully resolved value without any references or stuck operations? Unset values are concrete.

Declared at: llvm/include/llvm/TableGen/Record.h:552

¶llvm::Init* resolveReferences(
    llvm::Resolver& R) const

Description

This method is used by classes that refer to other variables which may not be defined at the time the expression is formed. If a value is set for the variable later, this method will be called on users of the value to allow the value to propagate out.

Declared at: llvm/include/llvm/TableGen/Record.h:555

Parameters

llvm::Resolver& R
