- Subject: Library ABI seriously broken!!
Hi,
sorry if the issue is already well known, but it's so serious that I
decided to post an heads up: today (not yesterday), the ABI is broken,
the size of many symbols exported by libstdc++ changed, see eg:
http://gcc.gnu.org/ml/gcc-testresults/2009-10/msg02895.html
http://gcc.gnu.org/ml/gcc-testresults/2009-10/msg02903.html
http://gcc.gnu.org/ml/gcc-testresults/2009-10/msg02904.html
I'm adding below some of the many error messages spilled by abi_check.
I *strongly* suspect:
2009-10-28 Jerry Quinn <jlquinn@optonline.net>
* mangle.c (mangle_type_string_for_rtti): Revert r149964.
(needs_fake_anon): Likewise.
(write_name): Likewise.
(write_nested_name): Likewise.
* cp-tree.h (mangle_type_string_for_rtti): Likewise.
(get_anonymous_namespace): Likewise.
* name-lookup.c (get_anonymous_namespace_name): Likewise.
* rtti.c (tinfo_name): Insert '*' in front of private names.
(tinfo_base_init): Use it.
2009-10-28 Jerry Quinn <jlquinn@optonline.net>
* libsupc++/tinfo.cc (operator=(const type_info&)): Compare by
pointer if name begins with '*'.
* libsupc++/typeinfo (type_info::name()): Likewise.
* libsupc++/tinfo2.cc (before): Likewise.
Please provide feedback ASAP.
Thanks,
Paolo.
