Rename files with same (case insensitive) name

[hiraditya]

Summary

This is causing issue with rebasing on mac because there is already a file DIModule.ll in the same directory.

https://reviews.llvm.org/D93462 added a new file dimodule.ll

LGTM to unbreak the checkout. @cchen15 can choose a different name if they want later.

Thanks for catching this for me. I don't work on Mac. :(

I don't see other tests using 'verify-' as prefix. Would it be more succinct to just call it dimodule-external-fortran.ll?

[hiraditya]

ok i'll rename this before commit.

[hiraditya]

rename

[cchen15]

Thanks a lot, Aditya. Again, my apologies for the screw-up. I will make sure I won't make the same mistake next time I add a new file.

This issue also affects Windows, so please commit this change.

[hiraditya]

It seems, I'm no longer having access to the llvm-project. Please commit this for me.

I need to setup access token because github has changed commit policy recently.

llvm/test/DebugInfo/X86/verify-dimodule-external-fortran.ll

 ; This test verifies that the debug info for an external Fortran module
 ; is correctly generated.
 ;
 ; To generate the test source, compile the following two files in order in
 ; the same directory (as the second compilation uses the .mod from the first):
 ; external_module.f90 (to compile: <fortran compiler> -g -c external_module.f90)
 ;   module external_module
 ;     real :: dummy
 ;   end module external_module
 ;
 ; em.f90 (to compile: <fortran compierl> -g -llvm-emit -c -S em.f90)
 ;   program use_external_module
 ;   use external_module
 ;   implicit none
 ;
 ;     real :: x
 ;     x = 2.0 + dummy
 ;
 ;   end program use_external_module
 ;
 ; The test would be in em.ll.
