The HP linkers and dynamic loaders don't like undefined weak symbols. GAS provides support for ".weak" using SOM secondary definition symbols on the 32-bit port. We use this under HP-UX 11 and it is good enough for most purposes. However, the semantics differ from that defined in the sysv ABI. The 64-bit support is a little better supported by the linker, but the dynamic linker still doesn't like undefined weak symbols. We don't support ".weak' under HP-UX 10 due to linker bugs. Either XFAIL or dg-require would be ok. If more tests are likely to be added, maybe dg-require would be better. Dave -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24827
