Code Issues Releases Activity

(unw_tdep_word_t): New type.

Browse source 
(ia64_regnum_t): Define well-known frame registers here and add
	TDEP-aliases for use by libunwind.h.
(unw_ia64_table_t): Use unw_tdep_word_t instead of unw_word_t so this
	file can be included by libunwind.h.
	Change type of "array" member to void *.  On OSes that support
	ILP32, it may point to a 32-bit unwind table.
