Diego Novillo - Re: [PATCH 3/5]: Use pointer_map in tree-cfg (original) (raw)

This is the mail archive of the gcc-patches@gcc.gnu.orgmailing list for the GCC project.

* Makefile.in (tree-cfg.o): Remove hashtab.h dependency.
* tree-cfg.c: Don't include hashtab.h.
(edge_to_cases): Declare as pointer_map.
(struct edge_to_cases_elt, edge_to_cases_hash, edge_to_cases_eq):
Delete.
(edge_to_cases_cleanup): Rewrite as pointer_map_traverse callback.
(start_recording_case_labels): Create edge_to_cases as pointer_map.
(end_recoding_case_labels): Cleanup edge_to_cases manually before
destroying it.
(record_switch_edge): Delete.
(get_cases_for_edge): Adjust for pointer_map API, inline
record_switch_edge (rewritten for new API), remove goto.
