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.

Referenced by get_rtx_for_ssa_name().
