[Bug fortran/32817] MODULE functions are not inlined

["fxcoudert at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #5 from fxcoudert at gcc dot gnu dot org  2009-05-02 16:26 -------
Now, inlining of non-CONTAINED procedures works when -fwhole-file is used (it
will be the default when the remaining bugs are fixed).

However, functions from used modules are still not inlined; a reduced testcase
is:

  module foomod
  contains
    integer function bar()
      bar = 1
    end function
  end module

  subroutine gee
    use foomod
    if (bar() == 0) call abort
  end subroutine

In this, the call to bar() should be inlined, but it is not (compile with "-O2
-fdump-tree-optimized -fwhole-file" and check the .optimized tree dump). The
same code, with a non-module global function, has the call inlined:

  integer function bar()
    bar = 1
  end function

  subroutine gee
    integer, external :: bar
    if (bar() == 0) call abort
  end subroutine
