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/LockFileManager.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'llvm/lib/Support/LockFileManager.cpp') diff --git a/llvm/lib/Support/LockFileManager.cpp b/llvm/lib/Support/LockFileManager.cpp index 5fd5299..6e934ba 100644 --- a/llvm/lib/Support/LockFileManager.cpp +++ b/llvm/lib/Support/LockFileManager.cpp @@ -60,7 +60,7 @@ LockFileManager::readLockFile(StringRef LockFileName) { MemoryBuffer::getFile(LockFileName); if (!MBOrErr) { sys::fs::remove(LockFileName); - return None; + return std::nullopt; } MemoryBuffer &MB = *MBOrErr.get(); @@ -77,7 +77,7 @@ LockFileManager::readLockFile(StringRef LockFileName) { // Delete the lock file.
