Constructor & Destructor Documentation

GlobalAlias::GlobalAlias	(	Type *	Ty,
		LinkageTypes	Linkage,
		const Twine &	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.

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

Reimplemented from llvm::GlobalValue.

Definition at line 79 of file GlobalAlias.h.

References llvm::Value::getValueID(), and llvm::Value::GlobalAliasVal.

llvm::GlobalAlias::DECLARE_TRANSPARENT_OPERAND_ACCESSORS ( Constant )

Provide fast operand accessors.

void GlobalAlias::eraseFromParent ( ) [virtual]

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

Implements llvm::GlobalValue.

Definition at line 221 of file Globals.cpp.

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

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 61 of file GlobalAlias.h.

References llvm::User::getOperand().

References llvm::User::getOperand().

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

Reimplemented from llvm::User.

Definition at line 38 of file GlobalAlias.h.

void GlobalAlias::removeFromParent ( ) [virtual]

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

Implements llvm::GlobalValue.

Definition at line 217 of file Globals.cpp.

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

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 247 of file Globals.cpp.

References getAliasedGlobal(), llvm::SmallPtrSet< PtrType, SmallSize >::insert(), and llvm::GlobalValue::mayBeOverridden().

void GlobalAlias::setAliasee ( Constant * GV )

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

Definition at line 225 of file Globals.cpp.

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