2005-03-17Do not create ridiculously huge DSNodes, as described in the comments.Chris Lattner
This speeds up the BU pass on 172.mgrid from 62.3 -> 0.1242s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20648 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-16remove use of compat_iterator.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20643 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-15make sure to mark nodes in the globals graph incomplete after computing itChris Lattner
so that external globals (and whatever they point to) are marked incomplete. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20628 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-15fix crashes when we only have a prototype for main.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20627 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-15Fix a crash that happens when mapping something like this:Chris Lattner
{ short, short } to short where the second short maps onto the second field of the first struct. In this case, the struct index is not aligned, so we should avoid calling getLink(2), which asserts out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20626 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-15Finally fix (the right way) the problem where functions like this:Chris Lattner
void foo() { G = 1; } would have an empty DSGraph even though G (a global) is directly used in the function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20619 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-15This mega patch converts us from using Function::a{iterator|begin|end} toChris Lattner
using Function::arg_{iterator|begin|end}. Likewise Module::g* -> Module::global_*. This patch is contributed by Gabor Greif, thanks! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20597 91177308-0d34-0410-b5e6-96231b3b80d8

2005-02-261 + 100 + 51 == 152, not 52.Chris Lattner
If we fold three constants together (c1+c2+c3), make sure to keep LHSC updated, instead of reusing (in this case), the 1 instead of the partial sum. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20337 91177308-0d34-0410-b5e6-96231b3b80d8
2005-02-25Handle null a bit more carefully.Chris Lattner
Actually teach dsa about select instructions. This doesn't affect the graph in any way other than not setting a spurious U marker on pointer nodes that are selected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20324 91177308-0d34-0410-b5e6-96231b3b80d8

2005-02-13Correct the recursive PHI node handling routines in a way that CANNOT induceChris Lattner
infinite loops (using the new replaceSymbolicValuesWithConcrete method). This patch reverts this patch: http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20050131/023830.html ... which was an attempted fix for this problem. Unfortunately, that patch caused test/Regression/Transforms/IndVarsSimplify/exit_value_tests.llx to fail and slightly castrated the entire analysis. This patch fixes it right. This patch is dedicated to jeffc, for making me deal with this. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20146 91177308-0d34-0410-b5e6-96231b3b80d8

2005-02-04If we have an indirect call site that calls N functions, inline the N functionsChris Lattner
into a temporary graph, remember it for later, then inline the tmp graph into the call site. In the case where there are other call sites to the same set of functions, this permits us to just inline the temporary graph instead of all of the callees. This turns N*M inlining situations into an N+M inlining situation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20036 91177308-0d34-0410-b5e6-96231b3b80d8
