ConstantFolding.cpp updated: 1.2 -> 1.3 --- Log message: For PR411: http://llvm.cs.uiuc.edu/PR411 : This patch is an incremental step towards supporting a flat symbol table. It de-overloads the intrinsic functions by providing type-specific intrinsics and arranging for automatically upgrading from the old overloaded name to the new non-overloaded name. Specifically: llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64 llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64 llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64 llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64 llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64 New code should not use the overloaded intrinsic names. Warnings will be emitted if they are used. --- Diffs of the changes: (+18 -7) ConstantFolding.cpp | 25 ++++++++++++++++++------- 1 files changed, 18 insertions(+), 7 deletions(-) Index: llvm/lib/Analysis/ConstantFolding.cpp diff -u llvm/lib/Analysis/ConstantFolding.cpp:1.2 llvm/lib/Analysis/ConstantFolding.cpp:1.3 --- llvm/lib/Analysis/ConstantFolding.cpp:1.2 Fri Jan 13 19:25:24 2006 +++ llvm/lib/Analysis/ConstantFolding.cpp Mon Jan 16 15:12:35 2006 @@ -35,15 +35,26 @@ const std::string &Name = F->getName(); switch (F->getIntrinsicID()) { - case Intrinsic::isunordered: - case Intrinsic::sqrt: + case Intrinsic::isunordered_f32: + case Intrinsic::isunordered_f64: + case Intrinsic::sqrt_f32: + case Intrinsic::sqrt_f64: case Intrinsic::bswap_i16: case Intrinsic::bswap_i32: case Intrinsic::bswap_i64: // FIXME: these should be constant folded as well - //case Intrinsic::ctpop: - //case Intrinsic::ctlz: - //case Intrinsic::cttz: + //case Intrinsic::ctpop_i8: + //case Intrinsic::ctpop_i16: + //case Intrinsic::ctpop_i32: + //case Intrinsic::ctpop_i64: + //case Intrinsic::ctlz_i8: + //case Intrinsic::ctlz_i16: + //case Intrinsic::ctlz_i32: + //case Intrinsic::ctlz_i64: + //case Intrinsic::cttz_i8: + //case Intrinsic::cttz_i16: + //case Intrinsic::cttz_i32: + //case Intrinsic::cttz_i64: return true; default: break; } @@ -125,7 +136,7 @@ return ConstantFP::get(Ty, log(V)); else if (Name == "log10" && V > 0) return ConstantFoldFP(log10, V, Ty); - else if (Name == "llvm.sqrt") { + else if (Name == "llvm.sqrt.f32" || Name == "llvm.sqrt.f64") { if (V >= -0.0) return ConstantFP::get(Ty, sqrt(V)); else // Undefined @@ -164,7 +175,7 @@ if (ConstantFP *Op2 = dyn_cast<ConstantFP>(Operands[1])) { double Op2V = Op2->getValue(); - if (Name == "llvm.isunordered") + if (Name == "llvm.isunordered.f32" || Name == "llvm.isunordered.f64") return ConstantBool::get(IsNAN(Op1V) || IsNAN(Op2V)); else if (Name == "pow") { _______________________________________________ llvm-commits mailing list llvm-commits@cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/llvm-commits
