Make opt_pass and gcc::pass_manager be GC-managed
2013-08-20 David Malcolm <dmalcolm@redhat.com>
Make opt_pass and gcc::pass_manager be GC-managed, so that pass
instances can own GC refs.
* Makefile.in (GTFILES): Add pass_manager.h and tree-pass.h.
* context.c (gcc::context::gt_ggc_mx): Traverse passes_.
(gcc::context::gt_pch_nx): Likewise.
(gcc::context::gt_pch_nx): Likewise.
* ggc.h (gt_ggc_mx <T>): New.
(gt_pch_nx_with_op <T>): New.
(gt_pch_nx <T>): New.
* passes.c (opt_pass::gt_ggc_mx): New.
(opt_pass::gt_pch_nx): New.
(opt_pass::gt_pch_nx_with_op): New.
(pass_manager::gt_ggc_mx): New.
(pass_manager::gt_pch_nx): New.
(pass_manager::gt_pch_nx_with_op): New.
(pass_manager::operator new): Use
ggc_internal_cleared_alloc_stat rather than xcalloc.
* pass_manager.h (class pass_manager): Add GTY((user)) marking.
(pass_manager::gt_ggc_mx): New.
(pass_manager::gt_pch_nx): New.
(pass_manager::gt_pch_nx_with_op): New.
* tree-pass.h (class opt_pass): Add GTY((user)) marking.
(opt_pass::operator new): New.
(opt_pass::gt_ggc_mx): New.
(opt_pass::gt_pch_nx): New.
(opt_pass::gt_pch_nx_with_op): New.
