PR c++/49264
	* gimple-fold.c (fold_stmt_1): Don't try to fold *& on the lhs
	if stmt folded into nothing.
	* tree-inline.c (fold_marked_statements): If a builtin at the
	end of a bb folded into nothing, just update cgraph edges
	and move to next bb.
	* cgraph.c (cgraph_update_edges_for_call_stmt_node): Allow new_stmt
	to be NULL.  Don't compute count and frequency if new_call is NULL.

	* g++.dg/opt/pr49264.C: New test.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with 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/ for how to report bugs usefully.
