Hi GCC developers,
GCC v4.6's gengtype will auto-generate Allocators for known structs and
unions, for example: ggc_alloc_tree2WeakVH for tree2WeakVH
https://github.com/xiangzhai/dragonegg/blob/master/include/dragonegg/gt-cache-4.6.inc#L24
but gengtype will not auto-generate ggc_alloc_XXX for GCC v6.x or v8.x
(git-20170816), for example: struct GTY((for_user)) tree2WeakVH
https://github.com/xiangzhai/dragonegg/blob/master/include/dragonegg/gt-cache-8.0.inc#L1284
As ChangeLog-2014 mentioned:
2014-05-17 Trevor Saunders <tsaund...@mozilla.com>
...
(ggc_alloc): Install the type's destructor as the finalizer if it
might do something.
Please give me some hint about ggc_alloc migration, thanks a lot!
