Reproducing script.
The attached reproducer shows inconsistent behavior between -MD and -MG modes:
+ clang++ -w -MQ ^ -x c++ -MD -E -frewrite-includes -MF - -o unit.o.ii unit.cxx
unit.cxx:1:10: error: 'hello.hpp' file not found with <angled> include; use
"quotes" instead
#include <hello.hpp>
^~~~~~~~~~~
"hello.hpp"
^: unit.cxx hello.hpp
1 error generated.
+ echo $?
1
+ clang++ -w -MQ ^ -x c++ -M -MG unit.cxx
^: unit.cxx hello.hpp
+ echo $?
0
It cannot be both an invalid include and a potentially generated header.</pre>
