c++: reinterpret_cast from prvalue to rvalue ref [PR98440]
In r260622 I allowed this under the general principle that [basic.lval]
"Whenever a prvalue appears as an operand of an operator that expects a
glvalue for that operand, the temporary materialization conversion (7.3.4)
is applied to convert the expression to an xvalue." But
[expr.reinterpret.cast] specifically excludes creating a temporary in this
case.
gcc/cp/ChangeLog:
PR c++/98440
* typeck.c (build_reinterpret_cast_1): Don't perform
temporary materialization.
gcc/testsuite/ChangeLog:
* g++.dg/cpp0x/rv-cast6.C: Expect reinterpret_cast error.
* g++.dg/cpp0x/reinterpret_cast2.C: Adjust message.
* g++.old-deja/g++.jason/rvalue3.C: Likewise.
