dump-minimization-hints prints negative-size ranges #151976
Description
When executing Clang with -dump-minimization-hints, a logically incorrect output is created: a range whose to has a smaller line number than from:
//--- 70C.h
template <typename >
struct qg;
template <typename >
struct qg;
template <typename T>
qg(T) -> qg<T>;
//--- DMA.cppmap
module "z" {
header "FM7.h"
}
//--- FM7.h
#include "70C.h"
//--- NS4.cc
#include "70C.h"
