Author: dim Date: Thu Nov 25 20:35:49 2010 New Revision: 215841 URL: http://svn.freebsd.org/changeset/base/215841 Log: Now that the fix for gcc PR 20218 is applied, and hidden attributes actually work, linking of libgcc_s.so.1 on ia64 will fail with: unwind-ia64.So(.text+0x1762): In function `_Unwind_FindEnclosingFunction': : undefined reference to `_Unwind_FindTableEntry' unwind-ia64.So(.text+0x1d82): In function `uw_frame_state_for': : undefined reference to `_Unwind_FindTableEntry' /usr/bin/ld: libgcc_s.so.1: hidden symbol `_Unwind_FindTableEntry' isn't defined Repair this by not hiding the _Unwind_FindTableEntry symbol; on FreeBSD, it is in libc, not in libgcc.
