2002-11-17Add hack to only consider indirect calls indirect if they do more than castChris Lattner
their source function git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4723 91177308-0d34-0410-b5e6-96231b3b80d8

2002-11-13Pass to compute various statisics related to DSGraphs.Vikram S. Adve
For now, this just computes the #indirect call sites and the avg. #callees per indirect call site (actually it prints both totals and the average is their ratio). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4705 91177308-0d34-0410-b5e6-96231b3b80d8

2002-11-12Fix two bugs:Chris Lattner
* The globals vector was getting broken and unsorted, this caused vortex to get badly pessimized * Node offset handling was being handled really poorly, and in particular we were not merging types with offsets right. This causes several graphs to be non-merged. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4699 91177308-0d34-0410-b5e6-96231b3b80d8

2002-11-11Complete rewrite of BU code to use Tarjan's SCC finding algorithm to driveChris Lattner
the algorithm instead of hand coded depth first iteration git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4694 91177308-0d34-0410-b5e6-96231b3b80d8
2002-11-11Mark stuff reachable by _AUX_ calls as incomplete in the BU graphChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4690 91177308-0d34-0410-b5e6-96231b3b80d8
2002-11-11Fix infinite loop in the BU algorithm. Unfortunately this dies a seriousChris Lattner
death when handling moderately sized SCC's, but what can you do git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4689 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4687 91177308-0d34-0410-b5e6-96231b3b80d8
2002-11-10Fix a bug that could trigger when varargs call sites had non-matching number ↵Chris Lattner
of arguments git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4683 91177308-0d34-0410-b5e6-96231b3b80d8
2002-11-10* Dramatically rework liveness evaluation.Chris Lattner
* Implement the first step of the Globals graph: Deleting nodes from function graphs. In practice, these nodes need to be moved to the globals graph, but this will be taken care of later. Note that the graphs computed right now are not strictly correct! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4681 91177308-0d34-0410-b5e6-96231b3b80d8

2002-11-10* Bottom-Up graphs print the Aux call vectorChris Lattner
* Significantly improve DEBUG output * Aggressively fold calls together if we inlined a graph that provides call nodes. * Add a bailout if the current graph has over 200 call nodes in it, this is a really whacky case that should never happen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4675 91177308-0d34-0410-b5e6-96231b3b80d8
2002-11-09eliminate the ability to remove global nodes from deadNodeElminate... for now.Chris Lattner
This slows stuff down a bit, but it should get much better before it gets any worse. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4666 91177308-0d34-0410-b5e6-96231b3b80d8

2002-11-08Fold arrays down to a single element. This causes huge wins on some benchmarksChris Lattner
for example: 197.parser (64M->14M), 164.gzip (14M->2.7M). The actual graphs represented should not change at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4643 91177308-0d34-0410-b5e6-96231b3b80d8
2002-11-08ONLY merge in the aux call sites, this causes a HUGE speedupChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4640 91177308-0d34-0410-b5e6-96231b3b80d8
2002-11-08Allow specification of whether the call sites should be copied, AND whetherChris Lattner
the aux call sites should be copied git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4639 91177308-0d34-0410-b5e6-96231b3b80d8

2002-11-08- Add a bunch of checking to make sure that dead nodes are not used after theyChris Lattner
are marked DEAD. This helped track down some bugs - Fix a bunch of bugs where we were doing work on nodes after they became dead - Add support for aux function call sites - Add support for not cloning call sites git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4633 91177308-0d34-0410-b5e6-96231b3b80d8

2002-11-08* actually handle constants (especially constantexprs) correctly.Chris Lattner
- This seems to dramatically improve many benchmarks, only slowing down gzip significantly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4621 91177308-0d34-0410-b5e6-96231b3b80d8

2002-11-07Implement ResolveCallSiteModRefInfo for IPModRef. computeModRef is not yet ↵Chris Lattner
done though! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4602 91177308-0d34-0410-b5e6-96231b3b80d8
2002-11-07Instead of using a bool that constant has to be explained, use a selfChris Lattner
explanitory enum instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4600 91177308-0d34-0410-b5e6-96231b3b80d8
2002-11-07Implement a new mergeInGraph method, which basically factors code out ofChris Lattner
the BU class. This will be used by the IPModRef class to do stuff, eventually perhaps the TD pass will use it also. Speaking of the TD pass, this also eliminates the self recursive case, which was broken, and couldn't occur anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4599 91177308-0d34-0410-b5e6-96231b3b80d8

2002-11-07Minor bugfix to enable generation of methcall.llvm.lib, objinst.llvm.lib, andChris Lattner
The problem was merging two unsized types like function's, ie int (int*) with int (uint *) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4594 91177308-0d34-0410-b5e6-96231b3b80d8
