Almost 400 c++ and libstdc++ testcases ICE on Tru64 UNIX since Jan's
patch
2011-05-06 Jan Hubicka <[email protected]>
* cgraph.c (cgraph_add_thunk): Create real function node instead
of alias node; finalize it and mark needed/reachale; arrange visibility
to be right and add it into the corresponding same comdat group list.
(dump_cgraph_node): Dump thunks.
as described in the PR.
He provided the following patch in private mail. I tested it on
alpha-dec-osf5.1b by rebuilding cc1plus and rerunning the g++ and
libstdc++-v3 testsuites: all failures were gone.
Approved in private mail, committed to mainline.
