2012-09-16Refactor the SROA visitors for partitioning an alloca and buildingChandler Carruth
partition use lists a bit. No functionality changed. These visitors are actually visiting a tuple of a Use and an offset into the alloca. However, we use the InstVisitor to handle the dispatch over the users, and so the Use and Offset are stored in class member variables and set just before each call to visit(). This is fairly awkward and makes the functions a bit harder to read, but its the only real option we have until InstVisitor can be rewritten to use variadic templates. However, this pattern shouldn't be followed on the helper member functions where there is no interface constraint from the visitor. We already were passing the instruction as a normal parameter rather than use the Use to get at it, start passing the offset as well. This will become more important in subsequent patches as the offset will in some cases change while visiting a single instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@164003 91177308-0d34-0410-b5e6-96231b3b80d8

wide vector types. It had patterns for zext-loading and extending. This commit adds patterns for loading a wide type, performing a bitcast, and extending.

2012-09-16Add alternative coalescing algorithm under a flag.Jakob Stoklund Olesen
The live range of an SSA value forms a sub-tree of the dominator tree. That means the live ranges of two values overlap if and only if the def of one value lies within the live range of the other. This can be used to simplify the interference checking a bit: Visit each def in the two registers about to be joined. Check for interference against the value that is live in the other register at the def point only. It is not necessary to scan the set of overlapping live ranges, this interference check can be done while computing the value mapping required for the final live range join. The new algorithm is prepared to handle more complicated conflict resolution - We can allow overlapping live ranges with different values as long as the differing lanes are undef or unused in the other register. The implementation in this patch doesn't do that yet, it creates code that is nearly identical to the old algorithm's, except: - The new stripCopies() function sees through multiple copies while the old RegistersDefinedFromSameValue() only can handle one. - There are a few rare cases where the new algorithm can erase an IMPLICIT_DEF instuction that RegistersDefinedFromSameValue() couldn't handle. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163991 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-16Fix problem when using LiveRangeQuery with block entries.Jakob Stoklund Olesen
A value that is live in to a basic block should be returned by valueIn() in LiveRangeQuery(getMBBStartIdx(MBB)), unless it is a PHI-def which should be returned by valueDefined() instead. Current code isn't using this functionality. Future code will. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163990 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-15Make LiveRangeQuery work for PHIDefs as well.Jakob Stoklund Olesen
If a PHI value happens to be live out from the layout predecessor of its def block, the def slot index will be in the middle of the segment: %vreg11 = [192r,240B:0)[352r,416B:2)[416B,496r:1) 0@192r 1@480B-phi %2@352r A LiveRangeQuery for 480 should return NULL from valueIn() since the PHI value is defined at the block entry, not live in to the block. No test case, future code depends on this functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@163971 91177308-0d34-0410-b5e6-96231b3b80d8
