2011-03-04Use an IndexedMap instead of a DenseMap for the live-out cache.Jakob Stoklund Olesen
This speeds up updateSSA() so it only accounts for 5% of the live range splitting time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126972 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-03There are times when the landing pad won't have a call to 'eh.selector' inBill Wendling
it. It's been assumed up til now that it would be in its immediate successor. However, this isn't necessarily the case. It could be in one of its successor's successors. Modify the code to more thoroughly check for an 'eh.selector' call in successors. It only looks at a successor if we get there as a result of an unconditional branch.

2011-03-03Renumber slot indexes uniformly instead of spacing according to the number ↵Jakob Stoklund Olesen
of defs. There are probably much larger speedups to be had by renumbering locally instead of looping over the whole function. For now, the greedy register allocator is 25% faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126926 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-03Represent sentinel slot indexes with a null pointer.Jakob Stoklund Olesen
This is much faster than using a pointer to a ManagedStatic object accessed with a function call. The greedy register allocator is 5% faster overall just from the SlotIndex default constructor savings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126925 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-03Avoid comparing invalid slot indexes, and assert that it doesn't happen.Jakob Stoklund Olesen
The SlotIndex created by the default construction does not represent a position in the function, and it doesn't make sense to compare it to other indexes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126924 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-03Fix PHI handling in LiveIntervals::shrinkToUses().Jakob Stoklund Olesen
We need to wait until we meet a PHIDef in its defining block before resurrecting PHIKills in the predecessors. This should unbreak the llvm-gcc-build-x86_64-darwin10-x-mingw32-x-armeabi bot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126905 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-02Avoid exponential blow-up when printing DAGs.Bob Wilson
David Greene changed CannotYetSelect() to print the full DAG including multiple copies of operands reached through different paths in the DAG. Unfortunately this blows up exponentially in some cases. The depth limit of 100 is way too high to prevent this -- I'm seeing a message string of 150MB with a depth of only 40 in one particularly bad case, even though the DAG has less than 200 nodes. Part of the problem is that the printing code is following chain operands, so if you fail to select an operation with a chain, the printer will follow all the chained operations back to the entry node. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126899 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-02Transfer simply defined values directly without recomputing liveness and SSA.Jakob Stoklund Olesen
Values that map to a single new value in a new interval after splitting don't need new PHIDefs, and if the parent value was never rematerialized the live range will be the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126894 91177308-0d34-0410-b5e6-96231b3b80d8
