ggc-zone.c: New file, zone allocating collector.
2003-10-26 Daniel Berlin <dberlin@dberlin.org>
* ggc-zone.c: New file, zone allocating collector.
* configure: Accept zone option for --with-gc
* configure.in: Ditto.
* ggc.h (ggc_pch_count_object): Pass bool indicating
stringiness. Update all callers.
(ggc_pch_alloc_object): Ditto.
(ggc_pch_write_object): Ditto.
(ggc_alloc_rtx): Use typed allocation, since all RTX's are of a single
type.
(ggc_alloc_rtvec): Ditto.
(ggc_alloc_tree): Use zone allocation, since some things using this macro
aren't a single typecode.
* ggc-none.c (ggc_alloc_typed): New function.
(ggc_alloc_zone): Ditto.
* ggc-page.c: Ditto on both functions.
