2005-04-02Change the ActualCallees callgraph from hash_multimap<Instruction,Function>Chris Lattner
to std::set<std::pair<Inst,Func>> to avoid duplicate entries. This speeds up the CompleteBU pass from 1.99s to .15s on povray and the eqgraph passes from 1.5s to .16s on the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21031 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
2005-03-18do not bother inlining nullary functions without return values. The onlyChris Lattner
effect these calls can have is due to global variables, and these passes all use the globals graph to capture their effect anyway. This speeds up the BU pass very slightly on perlbmk, reducing the number of dsnodes allocated from 98913 to 96423. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20676 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-13After finishing BU analysis, move all global variables from the globalsChris Lattner
graph into main and mark them complete. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20583 91177308-0d34-0410-b5e6-96231b3b80d8
2005-01-31Rename variables to work with VC++'s hokey scoping rules.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19942 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
2004-10-07Fix a nasty dangling pointer problem, due to a free'd pointer being left inChris Lattner
a map. This caused problems if a later object happened to be allocated at the free'd object's address. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16813 91177308-0d34-0410-b5e6-96231b3b80d8
2004-09-20'Pass' should now not be derived from by clients. Instead, they should deriveChris Lattner

2004-02-20There is no need to merge the globals graph into the function graphs at theChris Lattner
end of the BU and CBU passes. The globals will be marked incomplete, so it doesn't matter if they are missing some info, and merging isn't guaranteed to bring everything in anyway! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11684 91177308-0d34-0410-b5e6-96231b3b80d8
