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

2005-03-22Remove 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

2005-03-21Enhance 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

2005-03-21Remove a bunch of cruft and dead code for handling the case when types wereChris Lattner
defined in function constant pools. The assembler grammar has long disallowed functions from having constant pools, so all of this stuff is dead. This makes it an immediate error for functions to refer to nonexisting types, fixing Regression/Verifier/2005-03-21-UndefinedTypeReference.ll. Before, references to non-existing types in functions would only be detected when the subsequent function was parsed, due to the call to "ResolveTypes". "ResolveTypes" has not resolved any types for a long time, instead it emitted an error message if no resolved types are left. Since the only caller of this method is in the module code, just inline it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20726 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-21Make this method non-const. Making it const causes the const version ofTanya Lattner
getIGroup to be called instead of the non-const one. These two methods have (??) different behavior, so this change fixes bugs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20724 91177308-0d34-0410-b5e6-96231b3b80d8
2005-03-21Change the way that the TD pass inlines graphs. Instead of inlining eachChris Lattner
graph into all of the functions it calls when we visit a graph, change it so that the graph visitor inlines all of the callers of a graph into the current graph when it visits it. While we're at it, inline global information from the GG instead of from each of the callers. The GG contains a superset of the info that the callers do anyway, and this way we only need to do it one time (not one for each caller). This speeds up the TD pass substantially on several programs, and there is still room for improvement. For example, the TD pass used to take 147s on perlbmk, it now takes 36s. On povray, we went from about 5s to 1.97s. 134.perl is down from ~1s for Loc+BU+TD to .6s. The TD pass needs a lot of improvement though, which will occur with later patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20723 91177308-0d34-0410-b5e6-96231b3b80d8
