Here's an updated version of the patch series.
Changes since v1 of the patch series:
* Patch 1/4: this one is new: I noticed that the "public:" specifier
within class cgraph_node confused gengtype, leading it to erroneously
omit the first field within the class. This patch fixes this bug.
* Patch 2/4: this is the updated parser support for base classes. In
the previous version of the patch, it only attempted to parse the
base classes of GTY()-marked types. In this version of the patch it
only attempts to pass the bases of GTY()-marked types that are *not*
marked with GTY((user)) i.e. it ignores GTY((user)) types.
* Patch 3/4: this version incorporates suggestions by Michael Matz:
set_gc_used_type now visits base classes, and all inherited fields,
not just those in the class itself, and fixes the stylistic nits he
noted. walk_subclasses now only writes out cases for concrete
subclasses i.e. those with a "tag" GTY option. Similarly, I updated
USED_BY_TYPED_GC_P so that it emits allocators etc for subclasses
with a "tag" GTY option. I didn't fix the O(N^2) in walk_subclasses
(it doesn't seem to affect the speed of the build).
* Patch 4/4: this is new: it adds documentation to gty.texi about
how "desc" and "tag" can be used for class hierarchies.
Successfully bootstrapped and regtested together with the symtab patches
posted earlier, which port symtab/cgraph/varpool to use this machinery.
OK for trunk?
David Malcolm (4):
Ignore access-control keywords when parsing fields.
Parse base classes for GTY-marked types
Handle simple inheritance in gengtype.
