gdb/fortran: Allow for matching symbols with missing scope
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.
* NEWS: Add entry about nested function support.
gdb/testsuite/ChangeLog:
* gdb.fortran/nested-funcs-2.exp: Run tests with and without the
nested function prefix.
