From aadaaface2ec96ee30d92bf46faa41dd9e68b64d Mon Sep 17 00:00:00 2001 From: Kazu Hirata Date: Fri, 2 Dec 2022 21:11:44 -0800 Subject: [llvm] Use std::nullopt instead of None (NFC) This patch mechanically replaces None with std::nullopt where the compiler would warn if None were deprecated. The intent is to reduce the amount of manual work required in migrating from Optional to std::optional. This is part of an effort to migrate from llvm::Optional to std::optional: https://discourse.llvm.org/t/deprecating-llvm-optional-x-hasvalue-getvalue-getvalueor/63716 --- llvm/lib/Support/APInt.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'llvm/lib/Support/APInt.cpp') diff --git a/llvm/lib/Support/APInt.cpp b/llvm/lib/Support/APInt.cpp index 399b96c..ba2b2c1 100644 --- a/llvm/lib/Support/APInt.cpp +++ b/llvm/lib/Support/APInt.cpp @@ -2952,7 +2952,7 @@ llvm::APIntOps::SolveQuadraticEquationWrap(APInt A, APInt B, APInt C, // between them, so they would both be contained between X and X+1. if (!SignChange) { LLVM_DEBUG(dbgs() << __func__ << ": no valid solution\n"); - return None; + return std::nullopt; } X += 1; @@ -2964,7 +2964,7 @@ Optional llvm::APIntOps::GetMostSignificantDifferentBit(const APInt &A, const APInt &B) { assert(A.getBitWidth() == B.getBitWidth() && "Must have the same bitwidth"); if (A == B) - return llvm::None; + return std::nullopt; return A.getBitWidth() - ((A ^ B).countLeadingZeros() + 1); } -- cgit v1.1
