(melt_debug_garbcoll, melt_debuggc_eprintf): Moved from melt-runtime.c. (melt_obmag_string): New declaration. (struct meltobject_st, struct meltclosure_st, struct meltroutine_st, struct meltmixbigint_st, struct meltstring_st): using GTY variable_size and @@MELTGTY@@ comment. (melt_mark_special): added debug print. * gcc/melt-runtime.c: Improved comments. Include bversion.h, realmpfr.h, gimple-pretty-print.h. (ggc_force_collect) Declared external. (melt_forward_counter): Added. (melt_obmag_string): New function. (melt_alptr_1, melt_alptr_2, melt_break_alptr_1_at) (melt_break_alptr_2_at, melt_break_alptr_1,melt_break_alptr_1) (melt_allocate_young_gc_zone, melt_free_young_gc_zone): New. (delete_special, meltgc_make_special): Improved debug printf and use melt_break_alptr_1... (ggc_alloc_*) macros defined for backport to GCC 4.5 (melt_forwarded_copy): Don't clear the new destination zone in old GGC heap. (meltgc_add_out_raw_len): Use ggc_alloc_atomic. (meltgc_raw_new_mappointers, meltgc_raw_put_mappointers) (meltgc_raw_remove_mappointers): Corrected length argument to ggc_alloc_cleared_vec_entrypointermelt_st. (melt_really_initialize): Call melt_allocate_young_gc_zone. (melt_initialize): Set flag_plugin_added. (melt_val2passflag): TODO_verify_loops only in GCC 4.5 git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/branches/melt-branch@164424 138bc75d-0d04-0410-961f-82ee72b054a4
