Member Function Documentation

addChild()

void llvm::LexicalScope::addChild ( LexicalScope * S )

inline

Add a child scope.

Definition at line 69 of file LexicalScopes.h.

References LexicalScope().

closeInsnRange()

void llvm::LexicalScope::closeInsnRange ( LexicalScope * NewScope = nullptr )

inline

Create a range based on FirstInsn and LastInsn collected until now.

This is used when a new scope is encountered while walking machine instructions.

Definition at line 91 of file LexicalScopes.h.

dominates()

bool llvm::LexicalScope::dominates ( const LexicalScope * S ) const

inline

Return true if current scope dominates given lexical scope.

Definition at line 103 of file LexicalScopes.h.

References getDFSIn(), getDFSOut(), and LexicalScope().

dump()

LLVM_DUMP_METHOD void LexicalScope::dump

(

unsigned

Indent = 0

)

const

Print lexical scope.

extendInsnRange()

void llvm::LexicalScope::extendInsnRange ( const MachineInstr * MI )

inline

Extend the current instruction range covered by this scope.

Definition at line 81 of file LexicalScopes.h.

References assert(), and MI.
