re PR c/39928 (gimplify_expr failure)
2009-04-27 Richard Guenther <rguenther@suse.de>
PR middle-end/39928
* gimplify.c (gimplify_expr): If we are required to create
a temporary make sure it ends up as register.
* gcc.c-torture/compile/pr39928-1.c: New testcase.
* gcc.c-torture/compile/pr39928-2.c: Likewise.
