Field Documentation
| bitmap def_blocks_d::def_blocks |
Blocks that contain definitions of VAR. Bit I will be set if the Ith block contains a definition of VAR.
Referenced by get_current_def(), and initialize_flags_in_bb().
| bitmap def_blocks_d::livein_blocks |
Blocks where VAR is live-on-entry. Similar semantics as DEF_BLOCKS.
| bitmap def_blocks_d::phi_blocks |
Blocks that contain a PHI node for VAR.
Referenced by initialize_flags_in_bb().
