(finish_function): Don't finish a lambda scope for DECL_OMP_DECLARE_REDUCTION_P functions, nor cp_fold_function them nor cp_genericize them. * mangle.c (decl_mangling_context): Look through DECL_OMP_DECLARE_REDUCTION_P functions. * semantics.c (expand_or_defer_fn_1): For DECL_OMP_DECLARE_REDUCTION_P functions, use tentative linkage, don't keep their bodies with -fkeep-inline-functions and return false at the end. * g++.dg/gomp/openmp-simd-2.C: Don't expect bodies for DECL_OMP_DECLARE_REDUCTION_P functions. * testsuite/libgomp.c++/udr-20.C: New test. * testsuite/libgomp.c++/udr-21.C: New test.
