[gcc-plugin] hooking function declarations...

[Paweł Sikora]

hi,

i'm working on some gcc plugin and need to access all declarations
for function and classes. hooking on plugin_finish_type and  
plugin_pre_genericize
gives me afaics only record_trees for declared classes.
how can i obtain (in easiest way) function decls?

thanks for hints.
BR,
Pawel.

i should notice that i'm compiling only external library *header*
and in such case the plugin_pre_genericize isn't invoked.
afaics plugin_pre_genericize is invoked for classic translation unit.
is it a lack of implemenation in header-precompilation machinery?

There is a patch that may give you what you want.
http://gcc.gnu.org/ml/gcc-patches/2010-04/msg00315.html
It still has not been added to trunk, however.

Alternately, you could look at dehydra
(https://developer.mozilla.org/en/Dehydra) which had to solve a
similar problem.

it looks nice but introduces a redudancy in hooking, e.g. it reports
class methods via PLUGIN_FINISH_DECL while suitable decls are available
via PLUGIN_FINISH_TYPE/TYPE_METHODS chain.
is such redudancy expected?
