Detailed Description
This data structure is allocated for one-part variables at the time of emitting notes.
Field Documentation
| loc_exp_dep* onepart_aux::backlinks |
Doubly-linked list of dependent DVs. These are DVs whose cur_loc
computation used the expansion of this variable, and that ought
to be notified should this variable change. If the DV's cur_loc
expanded to NULL, all components of the loc list are regarded as
active, so that any changes in them give us a chance to get a
location. Otherwise, only components of the loc that expanded to
non-NULL are regarded as active dependencies.
| vec<loc_exp_dep, va_heap, vl_embed> onepart_aux::deps |
Dependencies actively used when expand FROM into cur_loc.
| expand_depth onepart_aux::depth |
The depth of the cur_loc expression.
| rtx onepart_aux::from |
This holds the LOC that was expanded into cur_loc. We need only
mark a one-part variable as changed if the FROM loc is removed,
or if it has no known location and a loc is added, or if it gets
a change notification from any of its active dependencies.
