* Rework passing parent pointers into complexpatterns, I forgotChris Lattner2010-09-211-1/+1
| | | | | | | | | | that complex patterns are matched after the entire pattern has a structural match, therefore the NodeStack isn't in a useful state when the actual call to the matcher happens. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114489 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | matched, allow ComplexPatterns to opt into getting the parent node of the operand being matched. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114472 91177308-0d34-0410-b5e6-96231b3b80d8
* fix a long standing wart: all the ComplexPattern's were beingChris Lattner2010-09-211-0/+2
| | | | | | | | | | | | passed the root of the match, even though only a few patterns actually needed this (one in X86, several in ARM [which should be refactored anyway], and some in CellSPU that I don't feel like detangling). Instead of requiring all ComplexPatterns to take the dead root, have targets opt into getting the root by putting SDNPWantRoot on the ComplexPattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114471 91177308-0d34-0410-b5e6-96231b3b80d8
* finish pushing MachinePointerInfo through selectiondags. At this point,Chris Lattner2010-09-211-3/+0
| | | | | | | | I think I've audited all uses, so it should be dependable for address spaces, and the pointer+offset info should also be accurate when there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114464 91177308-0d34-0410-b5e6-96231b3b80d8

* fix the code that infers SV info to be correct when dealingChris Lattner2010-09-211-4/+0
| | | | | | | with an indexed load/store that has an offset in the index. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114449 91177308-0d34-0410-b5e6-96231b3b80d8
* Add LiveInterval::find and use it for most LiveRange searching operationsJakob Stoklund Olesen2010-09-211-7/+33
| | | | | | | | | | | | instead of calling lower_bound or upper_bound directly. This cleans up the search logic a bit because {lower,upper}_bound compare LR->start by default, and it is usually simpler to search LR->end. Funnelling all searches through one function also makes it possible to replace the search algorithm with something faster than binary search. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114448 91177308-0d34-0410-b5e6-96231b3b80d8

This will be phased out soon assuming no issues with the builder system come up. To invoke the new construction mechanism just pass '-regalloc=pbqp -pbqp-builder' to llc. To provide custom constraints a Target just needs to extend PBQPBuilder and pass an instance of their derived builder to the RegAllocPBQP constructor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114272 91177308-0d34-0410-b5e6-96231b3b80d8
