The hash variables + are extended from FT_ULong to FT_PtrDist and new + hashing macro functions are introduced. The hash + values on 16-bit memory platforms are changed, but + ILP32 and LP64 are not changed. The hash value in + the cache subsystem is not reverted to the memory + address, so using signed type FT_PtrDist is safe. + + * src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash + function to replace FTC_FACE_ID_HASH() for portability. + * src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace + FTC_FACE_ID_HASH() by _FTC_FACE_ID_HASH(). + * src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto. + + * src/cache/ftccache.h (FTC_NodeRec): The type of the + member `hash' is changed from FT_UInt32 to FT_PtrDist. + + * src/cache/ftccache.h (FTC_Cache_Lookup): The type of the + argument `hash' is changed from FT_UInt32 to FT_PtrDist. + (FTC_Cache_NewNode): Ditto. + * src/cache/ftccache.c (ftc_cache_add): Ditto. + (FTC_Cache_Lookup): Ditto.
