Paul Thomas 30f9cd05c6 re PR fortran/31205 (aliased operator assignment produces wrong result)
2007-07-24 Paul Thomas <pault@gcc.gnu.org>

	PR fortran/31205
	PR fortran/32842
	* trans-expr.c (gfc_conv_function_call): Remove the default
	initialization of intent(out) derived types.
	* symbol.c (gfc_lval_expr_from_sym): New function.
	* matchexp.c (gfc_get_parentheses): Return argument, if it is
	character and posseses a ref.
	* gfortran.h : Add prototype for gfc_lval_expr_from_sym.
	* resolve.c (has_default_initializer): Move higher up in file.
	(resolve_code): On detecting an interface assignment, check
	if the rhs and the lhs are the same symbol.  If this is so,
	enclose the rhs in parenetheses to generate a temporary and
	prevent any possible aliasing.
	(apply_default_init): Remove code making the lval and call
	gfc_lval_expr_from_sym instead.
	(resolve_operator): Give a parentheses expression a type-
	spec if it has no type.
	* trans-decl.c (gfc_trans_deferred_vars): Apply the a default
	initializer, if any, to an intent(out) derived type, using
	gfc_lval_expr_from_sym and gfc_trans_assignment.  Check if
	the dummy is present.

	PR fortran/31205
	* gfortran.dg/alloc_comp_basics_1.f90 : Restore number of

	* gfortran.dg/interface_assignment_1.f90 : New test.

	PR fortran/32842
	* gfortran.dg/interface_assignment_2.f90 : New test.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the file COPYING
for copying permission.  The manuals, and some of the runtime
libraries, are under different terms; see the individual source files
for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.
