gdb/fortran: Allow for matching symbols with missing scopeusers/simark/fortran
This commit allows symbol matching within Fortran code without having to specify all of the symbol's scope. For example, given this Fortran code: module aaa contains subroutine foo print *, "hello." end subroutine foo end module aaa subroutine foo print *, "hello." end subroutine foo program test call foo contains subroutine foo print *, "hello." end subroutine foo subroutine bar use aaa call foo end subroutine bar end program test The user can now do this: (gdb) b foo Breakpoint 1 at 0x4006c2: foo. (3 locations) (gdb) info breakpoints Num Type Disp Enb Address What 1 breakpoint keep y <MULTIPLE> 1.1 y 0x00000000004006c2 in aaa::foo at nest.f90:4 1.2 y 0x0000000000400730 in foo at nest.f90:9 1.3 y 0x00000000004007c3 in test::foo at nest.f90:16 The user asks for a breakpoint on 'foo' and is given a breakpoint on all three possible 'foo' locations. The user is, of course, still able to specify the scope in order to place a single breakpoint on just one of the foo functions (or use 'break -qualified foo' to break on just the global foo). gdb/ChangeLog: * f-lang.c (f_language_defn): Use cp_get_symbol_name_matcher and cp_search_name_hash. gdb/testsuite/ChangeLog: * gdb.fortran/nested-funcs-2.exp: Run tests with and without the nested function prefix.
