- Including, but not limited to:
-
- * Traditional partial redundancy elimination.
-
- * Placement of caller/caller register save/restores.
-
- * Load/store motion.
-
- * Copy motion.
-
- * Conversion of flat register files to a stacked register

-
- * Dead load/store elimination.

- These routines accept as input:
-
- * Basic block information (number of blocks, lists of

- does not need to be basic block, they could be statements
- or functions.
-
- * Bitmaps of local properties (computed, transparent and
