            Bug ID: 104027
           Summary: [12 Regression] libgnat-12.so requires executable
                    stack on x86_64-linux
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jakub at gcc dot gnu.org
  Target Milestone: ---

while libgnat-11.so didn't (and some earlier too).
Seems the reason is a-nbnbig.o, which is empty and doesn't have .note.GNU-stack
section.
gnat1drv seems to exit (0) during the middle of compile_file, which means it
skips a big part of toplev.c (compile_file) cleanups, in particular
  targetm.asm_out.file_end ();
for this case.
