ActivateCleanupBlock()

void CodeGenFunction::ActivateCleanupBlock	(	EHScopeStack::stable_iterator	Cleanup,
		llvm::Instruction *	DominatingIP
	)

ActivateCleanupBlock - Activates an initially-inactive cleanup.

Activate a cleanup that was created in an inactivated state.

Cannot be used to resurrect a deactivated cleanup.

Parameters

DominatingIP

- An instruction which is known to dominate the current IP (if set) and which lies along all paths of execution between the current IP and the the point at which the cleanup comes into scope.

AddInitializerToStaticVarDecl()

llvm::GlobalVariable * CodeGenFunction::AddInitializerToStaticVarDecl	(	const VarDecl &	D,

AddInitializerToStaticVarDecl - Add the initializer for 'D' to the global variable that has already been created for it.

If the initializer has a different type than GV does, this may free GV and return a different one. Otherwise it just returns GV.

CreateDefaultAlignTempAlloca()

Address CodeGenFunction::CreateDefaultAlignTempAlloca	(	llvm::Type *	Ty,

CreateDefaultAlignedTempAlloca - This creates an alloca with the default ABI alignment of the given LLVM type.

CreateDefaultAlignTempAlloca - This creates an alloca with the default alignment of the corresponding LLVM type, which is not guaranteed to be related in any way to the expected alignment of an AST type that might have been lowered to Ty.

IMPORTANT NOTE: This is not generally the right alignment for any given AST type that happens to have been lowered to the given IR type. This should only ever be used for function-local, IR-driven manipulations like saving and restoring a value. Do not hand this address off to arbitrary IRGen routines, and especially do not pass it as an argument to a function that might expect a properly ABI-aligned value.

CreateIRTemp()

Address CodeGenFunction::CreateIRTemp	(	QualType	T,

CreateIRTemp - Create a temporary IR object of the given type, with appropriate alignment.

This routine should only be used when an temporary value needs to be stored into an alloca (for example, to avoid explicit PHI construction), but the type is the IR type, not the type appropriate for storing in memory.

That is, this is exactly equivalent to CreateMemTemp, but calling ConvertType instead of ConvertTypeForMem.

CreateTempAlloca() [1/2]

llvm::AllocaInst * CodeGenFunction::CreateTempAlloca	(	llvm::Type *	Ty,
		const Twine &	Name = "tmp",
		llvm::Value *	ArraySize = nullptr
	)

CreateTempAlloca - This creates an alloca and inserts it into the entry block if ArraySize is nullptr, otherwise inserts it at the current insertion point of the builder.

The caller is responsible for setting an appropriate alignment on the alloca.

ArraySize is the number of array elements to be allocated if it is not nullptr.

LangAS::Default is the address space of pointers to local variables and temporaries, as exposed in the source language. In certain configurations, this is not the same as the alloca address space, and a cast is needed to lift the pointer from the alloca AS into LangAS::Default. This can happen when the target uses a restricted address space for the stack but the source language requires LangAS::Default to be a generic address space. The latter condition is common for most programming languages; OpenCL is an exception in that LangAS::Default is the private address space, which naturally maps to the stack.

Because the address of a temporary is often exposed to the program in various ways, this function will perform the cast. The original alloca instruction is returned through Alloca if it is not nullptr.

The cast is not performaed in CreateTempAllocaWithoutCast. This is more efficient if the caller knows that the address will not be exposed.

EmitBlock - Emit the given block.

		const Twine &	Name = ""
	)

Same as IRBuilder::CreateInBoundsGEP, but additionally emits a check to detect undefined behavior when the pointer overflow sanitizer is enabled.

SignedIndices indicates whether any of the GEP indices are signed. IsSubtraction indicates whether the expression used to form the GEP is a subtraction.

Return the result of the given binary operation.

EmitCheckedLValue()

LValue CodeGenFunction::EmitCheckedLValue	(	const Expr *	E,
		TypeCheckKind	TCK
	)

Same as EmitLValue but additionally we generate checking code to guard against undefined behavior.

This is only suitable when we know that the address will be used to access the object.

EmitCheckSourceLocation()

llvm::Constant * CodeGenFunction::EmitCheckSourceLocation

(

SourceLocation

Loc

)

Emit a description of a source location in a format suitable for passing to a runtime sanitizer handler.

Emit a representation of a SourceLocation for passing to a handler in a sanitizer runtime library.

The format for this data is:

struct SourceLocation {
  const char *Filename;
  int32_t Line, Column;
};

For an invalid SourceLocation, the Filename pointer is null.

EmitCheckTypeDescriptor()

Emit a description of a type in a format suitable for passing to a runtime sanitizer handler.

Emit a type description suitable for use by a runtime sanitizer library.

The format of a type descriptor is

{ i16 TypeKind, i16 TypeInfo }

followed by an array of i8 containing the type name. TypeKind is 0 for an integer, 1 for a floating point value, and -1 for anything else.
