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

2005-02-13Correct 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

2005-01-30Make things more const-correct, adjust to changes in DSA interfaces.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19940 91177308-0d34-0410-b5e6-96231b3b80d8
2005-01-30* Make some methods more const correct.Chris Lattner
* Change the FunctionCalls and AuxFunctionCalls vectors into std::lists. This makes many operations on these lists much more natural, and avoids *exteremely* expensive copying of DSCallSites (e.g. moving nodes around between lists, erasing a node from not the end of the vector, etc). With a profile build of analyze, this speeds up BU DS from 25.14s to 12.59s on 176.gcc. I expect that it would help TD even more, but I don't have data for it. This effectively eliminates removeIdenticalCalls and children from the profile, going from 6.53 to 0.27s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19939 91177308-0d34-0410-b5e6-96231b3b80d8
2005-01-29Due to previous simplifications, we can simplify the data structures beingChris Lattner
used here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19913 91177308-0d34-0410-b5e6-96231b3b80d8

2005-01-29Remove some useless map operations. Loads/stores that are in the sameChris Lattner
BB as the load are not included in the Cand* sets at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19911 91177308-0d34-0410-b5e6-96231b3b80d8
2005-01-29Before doing expensive global analysis, check to make sure the pointer isChris Lattner
not invalidated on entry and on exit of the block. This fixes some N^2 behavior in common cases, and speeds up gcc another 5% to 22.35s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19910 91177308-0d34-0410-b5e6-96231b3b80d8
2005-01-29Minor simplification/speedup. Replaces a set lookup with a pointer comparison.Chris Lattner
This speeds up 176.gcc from 25.73s to 23.48s, which is 9.5% git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19907 91177308-0d34-0410-b5e6-96231b3b80d8
2005-01-29Eliminate generality that is not buying us anything. In particular, thisChris Lattner
will cause us to miss cases where the input pointer to a load could be value numbered to another load. Something like this: %X = load int* %P1 %Y = load int* %P2 Those are obviously the same if P1/P2 are the same. The code this patch removes attempts to handle that. However, since GCSE iterates, this doesn't actually buy us anything: GCSE will first replace P1 or P2 with the other one, then the load can be value numbered as equal. Removing this code speeds up gcse a lot. On 176.gcc in debug mode, this speeds up gcse from 29.08s -> 25.73s, a 13% savings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19906 91177308-0d34-0410-b5e6-96231b3b80d8

2005-01-28Remove this code as it is currently completely broken and unmaintained.Chris Lattner
If needed, this can be resurrected from CVS. Note that several of the interfaces (e.g. the IPModRef ones) are supersumed by generic AliasAnalysis interfaces that have been written since this code was developed (and they are not DSA specific). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19864 91177308-0d34-0410-b5e6-96231b3b80d8
