Hi! The testcase in the PR (too large for the testsuite) fails -fcompare-debug, because do_niy doesn't honor dump flags (TDF_NOUID in this case).
Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? 2016-04-15 Jakub Jelinek <ja...@redhat.com> PR c++/70675 * tree-pretty-print.c (do_niy): Add FLAGS argument, pass it down to dump_generic_node.
