2006-12-07Changed llvm_ostream et all to OStream. llvm_cerr, llvm_cout, llvm_null, areBill Wendling
now cerr, cout, and NullStream resp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32298 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-29Replacing std::iostreams with llvm iostreams. Some of these changes involveBill Wendling
adding a temporary wrapper around the ostream to make it friendly to functions expecting an LLVM stream. This should be fixed in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31990 91177308-0d34-0410-b5e6-96231b3b80d8

Close out this long standing bug by removing the remaining overloaded virtual functions in LLVM. The -Woverloaded-virtual option is now turned on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29934 91177308-0d34-0410-b5e6-96231b3b80d8

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

an incomplete node cannot alias a complete node. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20882 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-26Teach steens-aa two things about mod/ref information:Chris Lattner
1. If memory never escapes the program, it cannot be mod/ref'd by external functions. 2. If memory is global never mod/ref'd in the program, it cannot be mod/ref'd by any call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20867 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-23Make -steens-aa more conservative (aka correct) by making sure to obeyChris Lattner
incompleteness flags. Make it more aggressive by taking field sensitive information into account. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20781 91177308-0d34-0410-b5e6-96231b3b80d8

for the return node map. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20757 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
2005-01-30* 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

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
