* Only clone global nodes between graphs if both graphs have the global.Chris Lattner2004-02-271-0/+3
| | | | llvm-svn: 11928
* Instead of cloning the globals for main into the globals graph at the end ofChris Lattner2004-02-211-17/+11
| | | | | | | | | BU propagation, clone the globals into the GG of EACH FUNCTION that finishes processing! The GlobalsGraph *must* include all globals and effects from all functions in the program. Fixing this makes pool allocation work better on 175.vpr, but it still ultimately crashes. llvm-svn: 11686
* There is no need to merge the globals graph into the function graphs at theChris Lattner2004-02-201-5/+1
| | | | | | | | end of the BU and CBU passes. The globals will be marked incomplete, so it doesn't matter if they are missing some info, and merging isn't guaranteed to bring everything in anyway! llvm-svn: 11684
* When we complete the bottom-up pass, make sure to merge the globals in ↵Chris Lattner2004-02-171-0/+17
| | | | | | | | 'main' into the globals graph. llvm-svn: 11562
* Instead of callign removeTriviallyDeadNodes on the global graph every timeChris Lattner2004-02-081-0/+1
| | | | | | | | | removeDeadNodes is called, only call it at the end of the pass being run. This saves 1.3 seconds running DSA on 177.mesa (5.3->4.0s), which is pretty big. This is only possible because of the automatic garbage collection done on forwarding nodes. llvm-svn: 11178
* Avoid referencing deleted DSgraphs when merging an SCC into a larger SCC. ThisChris Lattner2004-01-311-9/+11

* Rematerialize nodes from the globals graph into the current graphVikram S. Adve2003-07-161-3/+9
| | | | | | | | | | after all callees are inlined into the current graph. NOTE: There's also a major bug fix for the BU pass in DataStructure.cpp, which ensures that resolvable indirect calls are not moved out to the globals graph, so that they are eventually inlined (if possible). llvm-svn: 7189

* * Bottom-Up graphs print the Aux call vectorChris Lattner2002-11-101-16/+42
| | | | | | | | | | * Significantly improve DEBUG output * Aggressively fold calls together if we inlined a graph that provides call nodes. * Add a bailout if the current graph has over 200 call nodes in it, this is a really whacky case that should never happen. llvm-svn: 4675
* eliminate the ability to remove global nodes from deadNodeElminate... for now.Chris Lattner2002-11-091-1/+1
| | | | | | | This slows stuff down a bit, but it should get much better before it gets any worse. llvm-svn: 4666

* Implement a new mergeInGraph method, which basically factors code out ofChris Lattner2002-11-071-44/+4
| | | | | | | | | | | | the BU class. This will be used by the IPModRef class to do stuff, eventually perhaps the TD pass will use it also. Speaking of the TD pass, this also eliminates the self recursive case, which was broken, and couldn't occur anyway. llvm-svn: 4599
