unsigned int ptr_info_def::align |
Alignment and misalignment of the pointer in bytes. Together align and misalign specify low known bits of the pointer. ptr & (align - 1) == misalign. When known, this is the power-of-two byte alignment of the object this pointer points into. This is usually DECL_ALIGN_UNIT for decls and MALLOC_ABI_ALIGNMENT for allocated storage. When the alignment is not known, it is zero. Do not access directly but use functions get_ptr_info_alignment, set_ptr_info_alignment, mark_ptr_info_alignment_unknown and similar.

unsigned int ptr_info_def::misalign |
When alignment is known, the byte offset this pointer differs from the above alignment. Access only through the same helper functions as align above.

struct pt_solution ptr_info_def::pt |
The points-to solution.
