Detailed Description

Constructor & Destructor Documentation

GlobalAlias::GlobalAlias	(	const Type *	Ty,
		LinkageTypes	Linkage,
		const std::string &	Name = `""`,
		Constant *	Aliasee = `0`,
		Module *	Parent = `0`
	)

GlobalAlias ctor - If a parent module is specified, the alias is automatically inserted into the end of the specified module's alias list.

Member Function Documentation

void* llvm::GlobalAlias::operator new ( size_t s ) [inline]

Reimplemented from llvm::User.

Definition at line 38 of file GlobalAlias.h.

llvm::GlobalAlias::DECLARE_TRANSPARENT_OPERAND_ACCESSORS ( Value )

Provide fast operand accessors.

bool GlobalAlias::isDeclaration ( ) const [virtual]

isDeclaration - Is this global variable lacking an initializer? If so, the global variable is defined in some other translation unit, and is thus only a declaration here.

Implements llvm::GlobalValue.

Definition at line 216 of file Globals.cpp.

References getAliasedGlobal(), and llvm::GlobalValue::isDeclaration().

void GlobalAlias::removeFromParent ( ) [virtual]

removeFromParent - This method unlinks 'this' from the containing module, but does not delete it.

Implements llvm::GlobalValue.

Definition at line 208 of file Globals.cpp.

References llvm::Module::getAliasList(), and llvm::GlobalValue::getParent().

void GlobalAlias::eraseFromParent ( ) [virtual]

eraseFromParent - This method unlinks 'this' from the containing module and deletes it.

Implements llvm::GlobalValue.

Definition at line 212 of file Globals.cpp.

References llvm::Module::getAliasList(), and llvm::GlobalValue::getParent().

void GlobalAlias::setAliasee ( Constant * GV )

set/getAliasee - These methods retrive and set alias target.

Definition at line 224 of file Globals.cpp.

References llvm::GlobalValue::getType(), llvm::Value::getType(), and llvm::Constant::setOperand().

Referenced by llvm::CloneModule(), and fold().

const Constant* llvm::GlobalAlias::getAliasee ( ) const [inline]

Definition at line 66 of file GlobalAlias.h.

References llvm::Constant::getOperand().

Referenced by getAliasedGlobal().

Constant* llvm::GlobalAlias::getAliasee ( ) [inline]

Definition at line 69 of file GlobalAlias.h.

References llvm::Constant::getOperand().

const GlobalValue * GlobalAlias::getAliasedGlobal ( ) const

getAliasedGlobal() - Aliasee can be either global or bitcast of global. This method retrives the global for both aliasee flavours.

Definition at line 233 of file Globals.cpp.

References BitCast, llvm::CallingConv::C, llvm::dyn_cast(), getAliasee(), llvm::ConstantExpr::getOpcode(), llvm::Constant::getOperand(), and GV.

Referenced by isDeclaration(), LinkAlias(), and resolveAliasedGlobal().

const GlobalValue * GlobalAlias::resolveAliasedGlobal ( bool stopOnWeak = true ) const

resolveAliasedGlobal() - This method tries to ultimately resolve the alias by going through the aliasing chain and trying to find the very last global. Returns NULL if a cycle was found. If stopOnWeak is false, then the whole chain aliasing chain is traversed, otherwise - only strong aliases.

Definition at line 251 of file Globals.cpp.

static bool llvm::GlobalAlias::classof ( const GlobalAlias * ) [inline, static]

Definition at line 84 of file GlobalAlias.h.

static bool llvm::GlobalAlias::classof ( const Value * V ) [inline, static]

Reimplemented from llvm::GlobalValue.
