2008-06-23Extract the x86_64 part for the executables.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52647 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23Simplify erase_one slightly. It's not necessary to preserveDan Gohman
the value of the element to be erased while the heap is being updated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52646 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23Revamp the loop unroller, extending it to correctly update PHI nodesDan Gohman
in the presence of out-of-loop users of in-loop values and the trip count is not a known multiple of the unroll count, and to be a bit simpler overall. This fixes PR2253. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52645 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23Remove option used to debug stack coloring bugs. It's no longer needed since ↵Evan Cheng
stack coloring is now bug free. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52644 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23Disable PRE. It's breaking bootstrapping.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52643 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23Move a DenseMap's declaration outside of a loop, and just callDan Gohman
clear() on each iteration. This avoids allocating and deallocating all of DenseMap's memory on each iteration. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52642 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23Use StringMap instead of std::map<std::string, SDNode*>.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52641 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23Add methods to StringMap to erase entries by key.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52640 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23Instead of adding an isSS field to LiveInterval to denote stack slot. Use ↵Evan Cheng
top bit of 'reg' instead. If the top bit is set, than the LiveInterval represents a stack slot live interval. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52639 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23First step to fix PR2088. Implement routine to compute the Wojciech Matyjewicz
multiplicative inverse of a given number. Modify udivrem to allow input and output pairs of arguments to overlap. Patch is based on the work by Chandler Carruth. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52638 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52637 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23Fix the types for NumElements variables, and add a commentDan Gohman
explaining why empty array constants use ValID::createUndef(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52636 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23Tighten the conditions under which we do PRE, remove some unneeded code, and ↵Owen Anderson
correct our preserved analyses list, since we do now change the CFG by splitting critical edges during PRE. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52631 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23minor tidying of comments.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52630 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-23Remove two convenience constructors because they're now private, and theDan Gohman
private implementation doesn't really need the convenience. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52629 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52624 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-23Port some integer multiplication fixes from LegalizeDAG.Duncan Sands
Bail out with an error if there is no libcall available for the given size of integer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52622 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-23At Chris' suggestion, move the liveness and worklist datastructures intoOwen Anderson
instance variables so they can be allocated just once, and reuse the worklist as the dead list as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52618 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-22Improve LSR's dead-phi detection to handle use-def cyclesDan Gohman
with more than two nodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52617 91177308-0d34-0410-b5e6-96231b3b80d8

ConstantExprs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52615 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52612 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-22Fix PR2369 by making scalarrepl more careful about promoting Chris Lattner
structures. Its default threshold is to promote things that are smaller than 128 bytes, which is sane. However, it is not sane to do this for things that turn into 128 *registers*. Add a cap on the number of registers introduced, defaulting to 128/4=32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52611 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-22Make custom lowering of ADD work correctly. ThisDuncan Sands
fixes PR2476; patch by Richard Osborne. The same problem exists for a bunch of other operators, but I'm ignoring this because they will be automagically fixed when the new LegalizeTypes infrastructure lands, since it already solves this problem centrally. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52610 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-21Fix for PR2479: correctly optimize expressions like (a > 13) & (a == Eli Friedman
15). See also PR1800, which is about the signed case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52608 91177308-0d34-0410-b5e6-96231b3b80d8
