[LLVMdev] JumpThreading and @llvm.dbg.declare()
...ccur once for each
variable.
I think the JumpThreading pass should lower all llvm.dbg.declare() into
llvm.dbg.value() the same way as the instcombine pass do (see
InstructionCombining.cpp):
// Lower dbg.declare intrinsics otherwise their value may be clobbered
// by instcombiner.
bool DbgDeclaresChanged = LowerDbgDeclare(F);
Do you agree? Ok to commit?
