* Two changes here:Chris Lattner2005-03-251-47/+41
| | | | | | | | | | | | 1. Instead of copying Local graphs to the BU graphs to start with, use spliceFrom to do the job (which is constant time in this case). On 176.gcc, this chops off .17s from the bu pass. 2. When building SCC graphs, simplify the logic and use spliceFrom to do the heavy lifting, instead of cloneInto/delete. This slices another .14s off 176.gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20826 91177308-0d34-0410-b5e6-96231b3b80d8

* Create an equivalence class of global variables that DSA will never be ableChris Lattner2005-03-191-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* do not bother inlining nullary functions without return values. The onlyChris Lattner2005-03-181-0/+7
| | | | | | | | | | 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

* If we have an indirect call site that calls N functions, inline the N functionsChris Lattner2005-02-041-57/+98
| | | | | | | | | | | | | 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

* * Make some methods more const correct.Chris Lattner2005-01-301-15/+27
| | | | | | | | | | | | | | | | | * 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
