Methods

¶GCFunctionInfo(const llvm::Function& F,
               llvm::GCStrategy& S)

Declared at: llvm/include/llvm/CodeGen/GCMetadata.h:101

Parameters

const llvm::Function& F

llvm::GCStrategy& S

¶void addSafePoint(llvm::MCSymbol* Label,
                  const llvm::DebugLoc& DL)

Description

addSafePoint - Notes the existence of a safe point. Num is the ID of the label just prior to the safe point (if the code generator is using MachineModuleInfo).

Declared at: llvm/include/llvm/CodeGen/GCMetadata.h:125

Parameters

llvm::MCSymbol* Label

const llvm::DebugLoc& DL

¶void addStackRoot(int Num,
                  const llvm::Constant* Metadata)

Description

addStackRoot - Registers a root that lives on the stack. Num is the stack object ID for the alloca (if the code generator is

Declared at: llvm/include/llvm/CodeGen/GCMetadata.h:113

Parameters

int Num

const llvm::Constant* Metadata

¶llvm::GCFunctionInfo::iterator begin()

Description

begin/end - Iterators for safe points.

¶uint64_t getFrameSize() const

Description

getFrameSize/setFrameSize - Records the function's frame size.

Declared at: llvm/include/llvm/CodeGen/GCMetadata.h:130

¶const llvm::Function& getFunction() const

Description

getFunction - Return the function to which this metadata applies.

¶llvm::GCFunctionInfo::live_iterator live_begin(
    const llvm::GCFunctionInfo::iterator& p)

Description

live_begin/live_end - Iterators for live roots at a given safe point.

Declared at: llvm/include/llvm/CodeGen/GCMetadata.h:144

Parameters

const llvm::GCFunctionInfo::iterator& p
