The comment for output_ttype should describe the TT_FORMAT and 
TT_FORMAT_SIZE nodes and TARGET_UNWIND_TABLES_DEFAULT needs an entry in 
tm.texi.

The middle-end changes look well segregated.  The ARM changes are within 
your purview.  The libstdc++ changes also look clean, and there have 
been no objections.

Therefore, the patch is OK for mainline.  However, as a courtesy, please 
do not check the patch in for 48 hours.  That will give the EH and/or 
libstdc++ people a last chance to object.

Thanks,
