* - Checkin of the alias analysis work:Chris Lattner2003-02-261-78/+187
| | | | | | | | | * Takes into account the size of the memory reference to determine aliasing. * Expose mod/ref information in a more consistent way * BasicAA can now disambiguate A[i][1] and A[j][2] for conservative request sizes llvm-svn: 5633

* This is a substantial rewrite of the AliasSetTracker class which now usesChris Lattner2003-02-241-111/+218
| | | | | | | | | | | a union-find based algorithm, is significantly faster, and is more general. It will also scale to handle call instructions correctly, which is a nice added bonus. This includes a new pass -print-alias-sets which can be used to show how alias sets are formed for a particular analysis. llvm-svn: 5619

* Split mem2reg promotion into two parts: a function which does the work, andChris Lattner2003-02-222-85/+112
| | | | | | a pass which wraps the function. This allows other passes to use the functionality llvm-svn: 5610

* - Eliminate provably non-pointer nodes from graphs.Chris Lattner2003-02-141-5/+22
| | | | | | | | | | | | | | This helps a lot of testcases, for example: New Time New #Nodes Old Time Old #Nodes 254.gap: 91.1024 21605 91.1397 22657 povray31: 2.7807 8613 3.0152 10338 255.vortex: 1.2034 8153 1.2172 8822 moria: .6756 3150 .7054 3877 300.twolf: .1652 2010 .1851 3270 Typically, testcases which use long and ulong integers a lot get better, f.e. povray above. llvm-svn: 5566
