2005-03-23a hack to allow count-aa to work with ds-aa :(Chris Lattner

2005-03-23Add two options to allow -count-aa to print queries either (1) all queries,Chris Lattner
or (2) only queries that are not successful (e.g. return may alias) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20790 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-23turn a dead conditional into an assert.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20787 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-23Totally gut mergeInGraph. There is absolutely no reason to be mergingChris Lattner
global roots in from callees to callers. The BU graphs do not have accurate globals information and all of the clients know it. Instead, just make sure the GG is up-to-date, and they will be perfectly satiated. This speeds up the BU pass on 176.gcc from 5.5s to 1.5s, and Loc+BU+TD from 7s to 2.7s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20786 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-22Several changes here:Chris Lattner
1. Increase max node size from 64->256 to avoid collapsing an important structure in 181.mcf 2. If we have multiple calls to an indirect call node with an indirect callee, fold these call nodes together, to avoid DSA turning apoc into a flaming fireball of death when analyzing 176.gcc. With this change, 176.gcc now takes ~7s to analyze for loc+bu+td, with 5.7s of that in the BU pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20775 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-22We might as well check the TD graphs as well, even though they are fine.Chris Lattner

cloning a graph. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20770 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-22Timers SHOULD NOT record the time taken to count the bytes allocated in the ↵Chris Lattner
heap! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20765 91177308-0d34-0410-b5e6-96231b3b80d8
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
2005-03-22When making a clone of a DSGraph from the BU pass, make sure to remember thatChris Lattner
this clone is supposed to be used for *ALL* of the functions in the SCC. This fixes the memory explosion problem the TD pass was having, reducing the memory growth from 24MB -> 3.5MB on povray and 270MB ->8.3MB on perlbmk! This obviously also speeds up the TD pass *a lot*. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20763 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-22Don't use operator[], use the new method instead, which is faster. This speedsChris Lattner
up the TD pass about 30% for povray and perlbmk. It's still not clear why copying a 5MB set of graphs turns into a 25MB set of graphs though :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20762 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-22Now that the dead ctor is gone, nothing uses the old node mapping exported byChris Lattner

2005-03-22two things: 1)evilness reduction patch, reduces the number of instructions ↵Andrew Lenharth
hiding in the small jump CC moving code. 2)implement div of small data types by FP DIV (also reduces evilness and should speed things up) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20756 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-21Enhance the TD pass to build composite graphs when we have indirect callChris Lattner
sites that target multiple callees. If we have a function table, for example, with N callees, and M callers call through it, we used to have to perform O(M*N) graph inlinings. Now we perform O(M+N) inlinings. This speeds up the td pass on perlbmk from 36.26s to 25.75s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20743 91177308-0d34-0410-b5e6-96231b3b80d8
