fieldoff Struct Reference

Data Fields
HOST_WIDE_INT	offset
unsigned HOST_WIDE_INT	size
unsigned	has_unknown_size: 1
unsigned	must_have_pointers: 1
unsigned	may_have_pointers: 1
unsigned	only_restrict_pointers: 1

Detailed Description

This structure is used during pushing fields onto the fieldstack
   to track the offset of the field, since bitpos_of_field gives it
   relative to its immediate containing type, and we want it relative
   to the ultimate containing object.
