openmp: Fix up handling of DECL_OMP_PRIVATIZED_MEMBER for bit-fields [PR95063]
The r11-15 change broke this testcase, as it now asserts type is equal to the type of the DECL_VALUE_EXPR, but for DECL_OMP_PRIVATIZED_MEMBER artificial vars mapping to bitfields it wasn't. Fixed by changing the DECL_OMP_PRIVATIZED_MEMBER var type in that case. 2020-05-12 Jakub Jelinek <jakub@redhat.com> PR c++/95063 * pt.c (tsubst_decl): Deal with DECL_OMP_PRIVATIZED_MEMBER for a bit-field. * g++.dg/gomp/pr95063.C: New test.
