LLVM: llvm::InstructionPrecedenceTracking Class Reference (original) (raw)

#include "[llvm/Analysis/InstructionPrecedenceTracking.h](InstructionPrecedenceTracking%5F8h%5Fsource.html)"

Public Member Functions
LLVM_ABI void insertInstructionTo (const Instruction *Inst, const BasicBlock *BB)
Notifies this tracking that we are going to insert a new instruction Inst to the basic block BB.
LLVM_ABI void removeInstruction (const Instruction *Inst)
Notifies this tracking that we are going to remove the instruction Inst It makes all necessary updates to internal caches to keep them consistent.
LLVM_ABI void removeUsersOf (const Instruction *Inst)
Notifies this tracking that we are going to replace all uses of Inst.
LLVM_ABI void clear ()
Invalidates all information from this tracking.
Protected Member Functions
LLVM_ABI const Instruction * getFirstSpecialInstruction (const BasicBlock *BB)
Returns the topmost special instruction from the block BB.
LLVM_ABI bool hasSpecialInstructions (const BasicBlock *BB)
Returns true iff at least one instruction from the basic block BB is special.
LLVM_ABI bool isPreceededBySpecialInstruction (const Instruction *Insn)
Returns true iff the first special instruction of Insn's block exists and dominates Insn.
virtual bool isSpecialInstruction (const Instruction *Insn) const =0
A predicate that defines whether or not the instruction Insn is considered special and needs to be tracked.
