Roger Sayle d211a298ce re PR c++/7503 ((x < Y ? X : Y) used for assignment causes wrong code) 
PR c++/7503
	* tree.c (lvalue_p_1):  Disallow MIN_EXPR and MAX_EXPR as lvalues
	if either operand has side-effects.
	* typeck.c (rationalize_conditional_expr): Assert that neither
	operand of MIN_EXPR or MAX_EXPR has side-effects.
	(build_modify_expr):  Add support for MIN_EXPR and MAX_EXPR.
	Check that the "lhs" is a valid lvalue, i.e. that neither operand
	of a MIN_EXPR or MAX_EXPR has a side-effect.

	* g++.dg/opt/pr7503-1.C: New testcase for COND_EXPR lvalues.
	* g++.dg/opt/pr7503-2.C: New testcase for <? and >? lvalues.
	* g++.dg/opt/pr7503-3.C: New testcase for invalid <? lvalue errors.
	* g++.dg/opt/pr7503-4.C: New testcase for <?= and >?= assignments.
	* g++.dg/opt/pr7503-5.C: New testcase for side-effects with <?=.

README 

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*.

See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
