[PATCH] D29125: [PPC] override the base implementatiosn of areLoadsFromSameBasePtr and shouldScheduleLoadsNear for PowerPC

[Sean Fertile via Phabricator via llvm-commits]

sfertile created this revision.

Implements overrides for the 'areLoadsFromSameBasePtr' function and 'shouldScheduleLoadsNear' function. Implementing these allows the pre-ra-scheduler to identify loads that are relatively close together and glue them together for scheduling purposes. The patch adds 2 back-end options allowing tuning of the number of vector/scalar loads to try to cluster together.
