    c++: TARGET_EXPR_ELIDING_P and std::move [PR107267]

    With -ffold-simple-inlines, we turn calls to std::move into the static_=
cast
    equivalent.  In this testcase, this exposes the FindResult temporary to
copy
    elision which is not specified by the standard, through an optimization=
 in
    gimplify_modify_expr_rhs.  Since the type is not TREE_ADDRESSABLE, this=
 is
    not detectable by the user, so we just need to soften the assert.

            PR c++/107267

    gcc/cp/ChangeLog:

            * cp-gimplify.cc (cp_gimplify_init_expr): Allow unexpected elis=
ion
            of trivial types.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/move2.C: New test.=
