LLVM backend for 6502
This also required making recursive simplifications until nothing changes or a hard limit (currently 3) is hit. With the simplification in place indvars can canonicalize loops of the form for (unsigned i = 0; i < a-b; ++i) into for (unsigned i = 0; i != a-b; ++i) which used to fail because SCEV created a weird umax expr for the backedge taken count. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157701 91177308-0d34-0410-b5e6-96231b3b80d8 |
