Add implementations of: bool isLegalICmpImmediate(int64_t Imm) const bool isLegalAddImmediate(int64_t Imm) const bool isTruncateFree(Type *Ty1, Type *Ty2) const bool isTruncateFree(EVT VT1, EVT VT2) const bool shouldConvertConstantLoadToIntImm(const APInt &Imm, Type *Ty) const Unfortunately, this regresses counter-register-based loop formation because some of the loops now end up in forms were SE cannot compute loop counts. However, nevertheless, the test-suite results favor committing: SingleSource/Benchmarks/BenchmarkGame/puzzle: 26% speedup MultiSource/Benchmarks/FreeBench/analyzer/analyzer: 21% speedup MultiSource/Benchmarks/MiBench/automotive-susan/automotive-susan: 20% speedup SingleSource/Benchmarks/Polybench/linear-algebra/kernels/trisolv/trisolv: 19% speedup SingleSource/Benchmarks/Polybench/linear-algebra/kernels/gesummv/gesummv: 15% speedup MultiSource/Benchmarks/FreeBench/pcompress2/pcompress2: 2% speedup MultiSource/Benchmarks/VersaBench/bmm/bmm: 26% slowdown git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206120 91177308-0d34-0410-b5e6-96231b3b80d8
