4610         The call to already_seen_tag introduces an O(N^2) when running
4611         gengtype on N, the number of tags, due to the repeated linear
4612         search, but currently max(N) is relatively small (the number of

4620         GIMPLE_OMP_RETURN happens to share the data layout of
4621         GIMPLE_OMP_ATOMIC_STORE, they are not otherwise related.
4622         (GIMPLE_OMP_PARALLEL, GIMPLE_OMP_TARGET): Likewise, rename
4623         underlying GSS value from GSS_OMP_PARALLEL to
4624         GSS_OMP_PARALLEL_LAYOUT to make clear that these gimple codes are
4625         not directly related; they merely share in-memory layout.
4626         (GIMPLE_OMP_SINGLE, GIMPLE_OMP_TEAMS): Likewise, rename GSS values
4627         for these two codes from GSS_OMP_SINGLE to GSS_OMP_SINGLE_LAYOUT.

4644         stmt->code == GIMPLE_EH_DISPATH.
4645
4646         (gimple_statement_omp_parallel): The existing class expressed
4647         a layout (GSS_OMP_PARALLEL), but the codes with that layout
4648         are not all related, so it makes more sense for this class to
4649         express a *code* (GIMPLE_OMP_PARALLEL).  GSS_OMP_PARALLEL has
4650         been renamed to GSS_OMP_PARALLEL_LAYOUT to express this, so

4657         as used by the various gimple_omp_taskreg_ accessors.
4658         (gimple_statement_omp_parallel): Reintroduce this class, this time
4659         as a subclass of gimple_statement_omp_taskreg to express the
4660         invariant stmt->code == GIMPLE_OMP_PARALLEL.
4661         (gimple_statement_omp_target) New class, subclassing
4662         gimple_statement_omp_parallel_layout, to express the invariant
4663         stmt->code == GIMPLE_OMP_TARGET.
4664         (gimple_statement_omp_task): Update to inherit from

4681         name as a subclass of gimple_statement_omp_atomic_store_layout
4682         with code == GIMPLE_OMP_ATOMIC_STORE.
4683         (gimple_statement_omp_return): New class, subclassing

22983         * passes.c (make_pass_instance): Now that passes have clone
22984         methods, rewrite this function to eliminate XNEW and memcpy
22985         calls that used hardcoded sizes.  Since this function no longer
22986         creates pass instances, rename it to...
22987         (add_pass_instance): ...this.  Document the old way that passes were
22988         numbered and flagged, and rework this function to continue using it.
22989         (next_pass_1): Add an initial_pass argument for use by
22990         add_pass_instance.
22991         (position_pass): When adding multiple instances of a pass, use
22992         the pass's clone method, rather than relying on the XNEW/memcpy
22993         within the former make_pass_instance (now add_pass_instance).
22994         (pass_manager::pass_manager): When invoking next_pass_1, also supply
22995         the initial instance of the current pass within the pass manager.
