2005-03-27Don't give up completely, maybe other AA can say something about this.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20873 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-26Cache mapping information for a call site after computing it for a mod/refChris Lattner
query. If the next mod/ref query happens to be for the same call site (which is extremely likely), use the cache instead of recomputing the callee/caller mapping. This makes -aa-eval ***MUCH*** faster with ds-aa git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20871 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20870 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-26remove some unsafe code that has long been deadChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20869 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-26slightly improve mod/ref for DSAA by checking the globals graph for fallbackChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20868 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20779 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-20#ifdef out a function only used by #ifdef'd code.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20700 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-18fix a bogus assertionChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20675 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-18Rewrite DSAA::getModRefInfo to compute the mapping between caller and calleeChris Lattner
to determine mod/ref behavior, instead of creating a *copy* of the caller graph and inlining the callee graph into the copy. This speeds up aa-eval on Ptrdist/yacr2 from 109.13s to 3.98s, and gives identical results. The speedup is similar on other programs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20669 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-17simplify this function a bit, allow DS-AA to build on/improve the mod/refChris Lattner
results returned by AA, not just use one or the other. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20662 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-17Two changes:Chris Lattner
1. Chain to the parent implementation of M/R analysis if we can't find any information. It has some heuristics that often do well. 2. Do not clear all flags, this can make invalid nodes by turning nodes that used to be collapsed into non-collapsed nodes (fixing crashes) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20659 91177308-0d34-0410-b5e6-96231b3b80d8

2004-09-20'Pass' should now not be derived from by clients. Instead, they should deriveChris Lattner
from ModulePass. Instead of implementing Pass::run, then should implement ModulePass::runOnModule. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16436 91177308-0d34-0410-b5e6-96231b3b80d8
