llvm::Instruction::mayHaveSideEffects

Declared in <llvm/IR/Instruction.h>

Side effects are: * Writing to memory. * Unwinding. * Not returning (e.g. an infinite loop).

Note that this does not consider malloc and alloca to have side effects because the newly allocated memory is completely invisible to instructions which don't use the returned value. For cases where this matters, isSafeToSpeculativelyExecute may be more appropriate.

True if this instruction may have side effects.
