* Totally gut mergeInGraph. There is absolutely no reason to be mergingChris Lattner2005-03-231-73/+47
| | | | | | | | | | | 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. llvm-svn: 20786

* Several changes here:Chris Lattner2005-03-221-19/+42
| | | | | | | | | | | | 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. llvm-svn: 20775
* We might as well check the TD graphs as well, even though they are fine.Chris Lattner2005-03-221-2/+2

* When making a clone of a DSGraph from the BU pass, make sure to remember thatChris Lattner2005-03-221-1/+8
| | | | | | | | | | 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*. llvm-svn: 20763
* Don't use operator[], use the new method instead, which is faster. This speedsChris Lattner2005-03-221-1/+1
