Dan Gohman 2d1be87ee4 Expand GEPs in ScalarEvolution expressions. SCEV expressions can now ... have pointer types, though in contrast to C pointer types, SCEV addition is never implicitly scaled. This not only eliminates the need for special code like IndVars' EliminatePointerRecurrence and LSR's own GEP expansion code, it also does a better job because it lets the normal optimizations handle pointer expressions just like integer expressions. Also, since LLVM IR GEPs can't directly index into multi-dimensional VLAs, moving the GEP analysis out of client code and into the SCEV framework makes it easier for clients to handle multi-dimensional VLAs the same way as other arrays. Some existing regression tests show improved optimization. test/CodeGen/ARM/2007-03-13-InstrSched.ll in particular improved to the point where if-conversion started kicking in; I turned it off for this test to preserve the intent of the test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69258 91177308-0d34-0410-b5e6-96231b3b80d8		2009-04-16 03:18:22 +00:00
