The new target macro UNWIND_FORCE_UNWIND_MASK in this patch * needs to be documented; * is only used in code in libgcc so should be in libgcc_tm.h via libgcc/config.host, not in the host-side gcc/config/ headers. (<http://gcc.gnu.org/wiki/Top-Level_Libgcc_Migration> lists existing target macros that have yet to be transitioned to libgcc_tm.h, though various parts of that page describe projects Rainer has now done.) -- Joseph S.
