* It turns out that this #include is needed because otherwiseChris Lattner2010-01-211-1/+1
| | | | | | | | | | | ValueMapper.cpp ends up calling an out of line __ZNK4llvm12PATypeHolder3getEv, which is a template and llvm-config determines arbitrarily to use the one in libipo. This sucks, but keeping the #include is a reasonable workaround. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94103 91177308-0d34-0410-b5e6-96231b3b80d8

* Re-implement the main strength-reduction portion of LoopStrengthReduction.Dan Gohman2010-01-2132-2614/+3030
| | | | | | | | | | | | | | | This new version is much more aggressive about doing "full" reduction in cases where it reduces register pressure, and also more aggressive about rewriting induction variables to count down (or up) to zero when doing so reduces register pressure. It currently uses fairly simplistic algorithms for finding reuse opportunities, but it introduces a new framework allows it to combine multiple strategies at once to form hybrid solutions, instead of doing all full-reduction or all base+index. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94061 91177308-0d34-0410-b5e6-96231b3b80d8
