c++: constexpr union member access folding [PR114709]
The object/offset canonicalization performed in cxx_fold_indirect_ref
is undesirable for union member accesses because it loses information
about the member being accessed which we may later need to diagnose an
inactive-member access. So this patch restricts the canonicalization
accordingly.
PR c++/114709
gcc/cp/ChangeLog:
* constexpr.cc (cxx_fold_indirect_ref): Restrict object/offset
canonicalization to RECORD_TYPE member accesses.
gcc/testsuite/ChangeLog:
* g++.dg/cpp0x/constexpr-union8.C: New test.
