Hello hackers, I seem to be having some trouble compiling the top of the llvm CVS tree... Is someone working on something involving IPModRef.cpp and the data structure graph? I have attached a make -k log. -Brian -- gaeke at uiuc.edu -------------- next part -------------- gmake[1]: Entering directory `/scratch/scratch0/gaeke/llvm-497cz/utils/Burg' gmake[1]: Nothing to be done for `all'. gmake[1]: Leaving directory `/scratch...

I have checked in 3 new analyses: 1. IPModRef (analyze -ipmodref): This is a Module pass that computes flow-insensitive context-sensitive interprocedural Mod/Ref information for a program. It uses DS Graphs to track mod/ref info for distinct data structures. 2. MemoryDepAnalysis (analyze -memdep): This is a Module pass (but wi...

...is can now take into consideration the size of a memory access to determine whether or not something aliases. This is crucial for a field-sensitive analysis to not cause bad transformations to happen. 2. Mod/Ref information is now a first class part of the AliasAnalysis interface. The IPModRef class does not yet implement the AliasAnalysis interface, but it should probably be changed to at some point. 3. A new pair of classes (AliasSetTracker & AliasSet) can be used to build alias sets for transformations that like to think of things that way. The LICM pass, for example, is...
