2005-03-22Remove an iteration pass over the entire scalarmap for each function createdChris Lattner
by not allowing integer constants to get into the scalar map in the first place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20764 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-20Build EC's for globals twice. The first is after constructing the initialChris Lattner
Globals Graph for the local pass, the second is after all of the locals graphs have been constructed. This allows for many additional global EC's to be recognized that weren't before. This speeds up analysis of programs like 177.mesa, where it changes DSA from taking 0.712s to 0.4018s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20711 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-20comment cleanupChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20699 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-19Create an equivalence class of global variables that DSA will never be ableChris Lattner
to tell apart anyway, and only track the leader for of these equivalence classes in our graphs. This dramatically reduces the number of GlobalValue*'s that appear in scalar maps, which A) reduces memory usage, by eliminating many many scalarmap entries and B) reduces time for operations that need to execute an operation for each global in the scalar map. As an example, this reduces the memory used to analyze 176.gcc from 1GB to 511MB, which (while it's still way too much) is better because it doesn't hit swap anymore. On eon, this shrinks the local graphs from 14MB to 6.8MB, shrinks the bu+td graphs of povray from 50M to 40M, shrinks the TD graphs of 130.li from 8.8M to 3.6M, etc. This change also speeds up DSA on large programs where this makes a big difference. For example, 130.li goes from 1.17s -> 0.56s, 134.perl goes from 2.14 -> 0.93s, povray goes from 15.63s->7.99s (!!!). This also apparently either fixes the problem that caused DSA to crash on perlbmk and gcc, or it hides it, because DSA now works on these. These both take entirely too much time in the TD pass (147s for perl, 538s for gcc, vs 7.67/5.9s in the bu pass for either one), but this is a known problem that I'll deal with later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20696 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

2005-02-25Handle 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
2005-02-24This instruction:Chris Lattner
X = gep null, ... Used to not create a scalar map entry for X, which caused clients to barf. This is bad. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20316 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

2004-07-07As much as I hate to say it, the whole setNode interface for DSNodeHandlesChris Lattner
is HOPELESSLY broken. The problem is that the embedded getNode call can change the offset of the node handle in unpredictable ways. As it turns out, all of the clients of this method really want to set both the node and the offset, thus it is more efficient (and less buggy) to just do both of them in one method call. This fixes some obscure bugs handling non-forwarded node handles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14660 91177308-0d34-0410-b5e6-96231b3b80d8
