2002-10-21 - Make DSCallSite not inherit from std::vector. Renamed methods slightly.Chris Lattner
Make copy ctor have two versions to avoid dealing with conditional template argument. DSCallSite ctor now takes all arguments instead of taking one and being populated later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4240 91177308-0d34-0410-b5e6-96231b3b80d8

2002-10-20Added a first-class representation for each call site that can beVikram S. Adve

2002-09-08* Add capability to recognize alias properties of the following common cases:Chris Lattner
- A[c1] cannot alias A[c2] where constants c1 != c2 - A[i] cannot alias B[j] if A & B are provably different arrays This should help out array based codes. For example, from bzip2 from spec, 3 additional loads can be GCSE'd, and _21_ additional loads can be LICMd due to this change. In a test example from the Spec GAP benchmark (vecffe.c), this change allows _52_ additional loads to be GCSE'd and _224_ additional LICM'd loads. Not bad for such a simple change. Other testcases show no change at all because they just don't use arrays. Not too suprising there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3616 91177308-0d34-0410-b5e6-96231b3b80d8
