Detailed Description
This structure (of which only a singleton SA exists) is used to pass around information between the outof-SSA functions, cfgexpand and expand itself.
Field Documentation
| var_map ssaexpand::map |
The computed partitions of SSA names are stored here.
Referenced by insert_rtx_to_part_on_edge().
| bitmap ssaexpand::partition_has_default_def |
If partition I contains an SSA name that has a default def,
bit I will be set in this bitmap.
| rtx* ssaexpand::partition_to_pseudo |
For a partition number I partition_to_pseudo[I] contains the
RTL expression of the allocated space of it (either a MEM or
a pseudos REG).
Referenced by discover_nonconstant_array_refs_r(), fini_vars_expansion(), and insert_rtx_to_part_on_edge().
| bitmap ssaexpand::values |
For an SSA name version V bit V is set iff TER decided that
its definition should be forwarded.
