c++: decltype of invalid non-dependent expr [PR57943]
We sometimes fail to reject an invalid non-dependent operand to decltype
when inside a template, because finish_decltype_type resolves the
decltype to the TREE_TYPE of the operand before we ever instantiate and
fully process the operand. Fix this by adding a call to
instantiate_non_dependent_expr_sfinae in finish_decltype_type.
gcc/cp/ChangeLog:
PR c++/57943
* semantics.c (finish_decltype_type): Call
instantiate_non_dependent_expr_sfinae on the expression.
gcc/testsuite/ChangeLog:
PR c++/57943
* g++.dg/cpp0x/decltype76.C: New test.
