Hal Finkel e05b232c20 [PowerPC/BlockPlacement] Allow target to provide a per-loop alignment preference ... The existing code provided for specifying a global loop alignment preference. However, the preferred loop alignment might depend on the loop itself. For recent POWER cores, loops between 5 and 8 instructions should have 32-byte alignment (while the others are better with 16-byte alignment) so that the entire loop will fit in one i-cache line. To support this, getPrefLoopAlignment has been made virtual, and can be provided with an optional MachineLoop* so the target can inspect the loop before answering the query. The default behavior, as before, is to return the value set with setPrefLoopAlignment. MachineBlockPlacement now queries the target for each loop instead of only once per function. There should be no functional change for other targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225117 91177308-0d34-0410-b5e6-96231b3b80d8		2015-01-03 17:58:24 +00:00
