[PATCH] D53522: [Frontend] Include module map header declaration in dependency file output

[Volodymyr Sapsai via Phabricator via cfe-commits]

vsapsai added a comment.

The test case I've promised is

  touch a.h
  touch b.h
  touch c.h
  ln -s b.h d.h
  
  echo '#include "a.h"' > umbrella.h
  echo '#include "b.h"' >> umbrella.h
  
  echo '#include "b.h"' > test_case.c
  
  cat <<EOF > module.modulemap
  module my_module {
    umbrella header "umbrella.h" export *
    header "c.h" export *
    header "d.h" export *
  }
  EOF
  
  clang -cc1 -fmodules -fimplicit-module-maps -fmodules-cache-path=./cache ./test_case.c -MT test_case.o -dependency-file -

Expected b.h to be present in `test_case.o` dependencies but it's not.

Keep in mind this test case can be unrelated to your change.
