/* The following code implements gcse after reload, the purpose of this
|
|
|
|
|
pass is to cleanup redundant loads generated by reload and other
|
|
|
|
|
optimizations that come after gcse. It searches for simple inter-block
|
|
|
|
|
redundancies and tries to eliminate them by adding moves and loads
|
|
|
|
|
in cold places.
|
|
|
|
|
|
|
|
|
|
Perform partially redundant load elimination, try to eliminate redundant
|
|
|
|
|
loads created by the reload pass. We try to look for full or partial
|
|
|
|
|
redundant loads fed by one or more loads/stores in predecessor BBs,
|
|
|
|
|
and try adding loads to make them fully redundant. We also check if
|
|
|
|
|
it's worth adding loads to be able to delete the redundant load.
|
|
|
|
|
|
|
|
|
|
Algorithm:
|
|
|
|
|
1. Build available expressions hash table:
|
|
|
|
|
For each load/store instruction, if the loaded/stored memory didn't
|
|
|
|
|
change until the end of the basic block add this memory expression to
|
|

the hash table.

|
|
|
|
2. Perform Redundancy elimination:
|
|
|
|
|
For each load instruction do the following:
|
|
|
|
|
perform partial redundancy elimination, check if it's worth adding
|
|
|
|
|
loads to make the load fully redundant. If so add loads and
|
|
|
|
|
register copies and delete the load.
|
|
|
|
|
3. Delete instructions made redundant in step 2.
|
|
|
|
|
|
|
|
|
|
Future enhancement:
|
|
|
|
|
If the loaded register is used/defined between load and some store,
|
|
|
|
|
look for some other free register between load and all its stores,
|
|
|
|
|
and replace the load with a copy from this register to the loaded
|
|
|
|
|
register.
