1 ; This test verifies that the debug info for an external Fortran module
2 ; is correctly generated.
4 ; To generate the test source, compile the following two files in order in
5 ; the same directory (as the second compilation uses the .mod from the first):
6 ; external_module.f90 (to compile: <fortran compiler> -g -c external_module.f90)
7 ; module external_module
9 ; end module external_module
11 ; em.f90 (to compile: <fortran compierl> -g -llvm-emit -c -S em.f90)
12 ; program use_external_module
19 ; end program use_external_module
21 ; The test would be in em.ll.
