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

2005-03-19Switch to use the new interface for the EquivalenceClasses class, and fixChris Lattner
a bug involving SCC's who have multiple members that are part of an EC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20678 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

2005-03-18remove a bogus optimization. This only works if there are no globals in theChris Lattner
graph, and the combination of a function that does not reference globals, takes not arguments and returns no value is pretty rare. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20670 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-18Rewrite DSAA::getModRefInfo to compute the mapping between caller and calleeChris Lattner
to determine mod/ref behavior, instead of creating a *copy* of the caller graph and inlining the callee graph into the copy. This speeds up aa-eval on Ptrdist/yacr2 from 109.13s to 3.98s, and gives identical results. The speedup is similar on other programs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20669 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-17Two changes:Chris Lattner
1. Chain to the parent implementation of M/R analysis if we can't find any information. It has some heuristics that often do well. 2. Do not clear all flags, this can make invalid nodes by turning nodes that used to be collapsed into non-collapsed nodes (fixing crashes) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20659 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-15Fix a crash that happens when mapping something like this:Chris Lattner
{ short, short } to short where the second short maps onto the second field of the first struct. In this case, the struct index is not aligned, so we should avoid calling getLink(2), which asserts out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20626 91177308-0d34-0410-b5e6-96231b3b80d8
