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
2002-11-07Rename DataStructureAnalysis namespace to DSChris Lattner

2002-11-06Dramatically simplify internal DSNode representation, get implementationChris Lattner
*FULLY OPERATIONAL* and safe. We are now capable of completely analyzing at LEAST the Olden benchmarks + 181.mcf git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4562 91177308-0d34-0410-b5e6-96231b3b80d8
2002-11-03Rename ValueMap to ScalarMapChris Lattner

2002-11-03Rename NewNode flag to HeapNodeChris Lattner

2002-11-02Implement the "unknown flag" which mainly consists of aligning printing codeChris Lattner

2002-11-02Stop representing scalars as explicit nodes in the graph. Now the onlyChris Lattner
nodes in the graph are memory objects, which is very nice. This also greatly reduces the size and memory footprint for DSGraphs. For example, the local DSGraph for llu went from 65 to 13 nodes with this change. As a side bonus, dot seems to lay out the graphs slightly better too. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4488 91177308-0d34-0410-b5e6-96231b3b80d8
2002-10-31Remove dead codeChris Lattner

2002-10-31This fixes all kinds of problems with array handling. There are still bugs toChris Lattner
be fixed, but we are getting much closer now. * Make DSNode::TypeRec a full fledged DSTypeRec type. * Add methods used to update and access the typerecords elements * Add methods to query if and to cause a node to be completely folded * DSGraph construction doesn't use the allocation type for anything at all, now nodes get their type information based on how they are used. * Fixed a bug with global value handling introduced in the last checkin * GEP support is now much better, arrays are handled correctly. The array flag is now updated in type records. There are still cases that are not handled yet (we do not detect pessimizations), but getting much closer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4465 91177308-0d34-0410-b5e6-96231b3b80d8
2002-10-21Don't create a new node for every reference to a global. This caused a hugeChris Lattner
node explosion that doesn't help anything at all. In previous versions of the representation this DID help, but not anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4249 91177308-0d34-0410-b5e6-96231b3b80d8
2002-10-21 - Make DSCallSite not inherit from std::vector. Renamed methods slightly.Chris Lattner
Make copy ctor have two versions to avoid dealing with conditional template argument. DSCallSite ctor now takes all arguments instead of taking one and being populated later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4240 91177308-0d34-0410-b5e6-96231b3b80d8

2002-10-20Remove spurious caller pointer in DSCallSite.Vikram S. Adve
Also add functions to access pointer argument nodes cleanly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4235 91177308-0d34-0410-b5e6-96231b3b80d8
2002-10-20Added a first-class representation for each call site that can beVikram S. Adve
used in the DS graphs. Essentially, what was vector<DSNodeHandle> before is now a DSCallSite with the same vector, plus pointers to the CallInst and the caller Function. The special-purpose class BUDataStructure::CallSite is no longer needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4228 91177308-0d34-0410-b5e6-96231b3b80d8

2002-10-02 * Implement fully general merging of array subscripts on demand! ThisChris Lattner
does not handle the initial pointer index case yet though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4012 91177308-0d34-0410-b5e6-96231b3b80d8
2002-10-01Checkin some major reworks of data structure analysis. This is not done,Chris Lattner
nor does it work very well, but I need to get it checked in before I break the tree unintentionally. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3996 91177308-0d34-0410-b5e6-96231b3b80d8
2002-08-22Eliminated the MemAccessInst class, folding contents into GEP class.Chris Lattner

2002-08-22Load & StoreInst no longer derive from MemAccessInst, so we don't haveChris Lattner
to handle indexing anymore git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3485 91177308-0d34-0410-b5e6-96231b3b80d8

2002-07-27* Standardize how analysis results/passes as printed with the print() virtualChris Lattner
methods * Eliminate AnalysisID: Now it is just a typedef for const PassInfo* * Simplify how AnalysisID's are initialized * Eliminate Analysis/Writer.cpp/.h: incorporate printing functionality into the analyses themselves. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3115 91177308-0d34-0410-b5e6-96231b3b80d8
2002-07-22Always create a shadow node for a store instruction, even if it's storingChris Lattner
a scalar value. Likewise for load instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2990 91177308-0d34-0410-b5e6-96231b3b80d8
