Here is a patch to implement that. I chose to keep the 3 dumps predefined
dumps and just tweak their registered number, otherwise the changes would be
bigger. The patch additionally renames TDI_generic to TDI_gimple (to match
the dump name and content) and because we have more than 256 dumps these
days and we register them all even at -O0, the patch avoids 4 unnecessary
reallocations. Ok for trunk if testing passes?
2017-06-05 Jakub Jelinek <jakub@redhat.com>
* dumpfile.h (enum tree_dump_index): Rename TDI_generic to
TDI_gimple.
(class dump_manager): Add register_dumps method.
* dumpfile.c: Include langhooks.h.
(dump_files): Use 0 instead of 3/4/5 for TDI_{original,gimple,nested}.
(FIRST_AUTO_NUMBERED_DUMP): Decrease to 1.
(FIRST_ME_AUTO_NUMBERED_DUMP): Define.
(dump_manager::dump_register): Start with 512 entries instead of 32.
(dump_manager::register_dumps): New method.
* toplev.c (general_init): Instead of invoking register_dumps
langhook, invoke register_dumps method on the dump manager.
* gimplify.c (gimplify_function_tree): Use TDI_gimple instead of
TDI_generic.
* gimple-parser.c (c_parser_parse_gimple_body): Use TDI_gimple instead
of TDI_generic.
