Detailed Description

A stack of loop information corresponding to loop nesting levels.

This stack can be used to prepare attributes which are applied when a loop is emitted.

◆ getCurLoopID()

llvm::MDNode* clang::CodeGen::LoopInfoStack::getCurLoopID ( ) const
inline

Return the top loop id metadata.

References getInfo().

◆ getCurLoopParallel()

bool clang::CodeGen::LoopInfoStack::getCurLoopParallel ( ) const
inline

Return true if the top loop is parallel.

◆ InsertHelper()

void LoopInfoStack::InsertHelper ( llvm::Instruction *  I) const

Function called by the CodeGenFunction when an instruction is created.

Definition at line 286 of file CGLoopInfo.cpp.

◆ pop()

void LoopInfoStack::pop ( )

End the current loop.

Definition at line 281 of file CGLoopInfo.cpp.

◆ push() [1/2]

void clang::CodeGen::LoopInfoStack::push ( llvm::BasicBlock *  Header,
const llvm::DebugLoc &  StartLoc,
const llvm::DebugLoc &  EndLoc 
)

Begin a new structured loop.

The set of staged attributes will be applied to the loop and then cleared.
