Detailed Description

'{ a, b, c }' - Represents an initializer for a BitsRecTy value.

It contains a vector of bits, whose size is determined by the type.

◆ classof()

References I, and llvm::Init::IK_BitsInit.

◆ convertInitializerBitRange()

Init * BitsInit::convertInitializerBitRange ( ArrayRef< unsigned >  Bits) const
overridevirtual

This function is used to implement the bit range selection operator.

Given a value, it selects the specified bits, returning them as a new Init of type bits. If it is not legal to use the bit selection operator on this value, null is returned.

Reimplemented from llvm::TypedInit.

Definition at line 380 of file Record.cpp.

References llvm::tgtok::Bits, llvm::numbers::e, get(), getBit(), getNumBits(), and i.

◆ convertInitializerTo()

Init * BitsInit::convertInitializerTo ( RecTy Ty) const
overridevirtual

Convert to a value whose type is Ty, or return null if this is not possible.

This can happen if the value's type is convertible to Ty, but there are unresolved references.

Reimplemented from llvm::TypedInit.

Definition at line 353 of file Record.cpp.

◆ get()

◆ getAsString()

std::string BitsInit::getAsString ( ) const
overridevirtual

Convert this value to a literal form.

Implements llvm::Init.

References llvm::tgtok::Bit, llvm::numbers::e, getBit(), getNumBits(), and i.

◆ getBit()

Init* llvm::BitsInit::getBit ( unsigned  Bit) const

Get the Init value of the specified bit.

Implements llvm::Init.

◆ getNumBits()

unsigned llvm::BitsInit::getNumBits ( ) const

◆ isComplete()

bool llvm::BitsInit::isComplete ( ) const

Is this a complete value with no unset (uninitialized) subvalues?

Reimplemented from llvm::Init.

Definition at line 527 of file Record.h.

References getBit(), getNumBits(), i, and llvm::Init::isComplete().

◆ isConcrete()

bool BitsInit::isConcrete ( ) const
overridevirtual

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

Reimplemented from llvm::Init.

References llvm::makeArrayRef(), and ProfileBitsInit().

◆ resolveReferences()

Init * BitsInit::resolveReferences ( Resolver R) const
overridevirtual

This function 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.
