2022-12-20[Clang] Prepare for llvm::Optional becoming std::optional.Benjamin Kramer1-11/+5
The needed tweaks are mostly trivial, the one nasty bit is Clang's usage of OptionalStorage. To keep this working old Optional stays around as clang::CustomizableOptional, with the default Storage removed. Optional<File/DirectoryEntryRef> is replaced with a typedef. I tested this with GCC 7.5, the oldest supported GCC I had around. Differential Revision: https://reviews.llvm.org/D140332
2022-12-18Revert "[clang] Convert OptionalFileEntryRefDegradesToFileEntryPtr to ↵Krzysztof Parzyszek1-10/+13
std::optional" This reverts commit 8f0df9f3bbc6d7f3d5cbfd955c5ee4404c53a75d. The Optional*RefDegradesTo*EntryPtr types want to keep the same size as the underlying type, which std::optional doesn't guarantee. For use with llvm::Optional, they define their own storage class, and there is no way to do that in std::optional. On top of that, that commit broke builds with older GCCs, where std::optional was not trivially copyable (static_assert in the clang sources was failing).

2022-04-14[clang][lex] NFCI: Use FileEntryRef in PPCallbacks::InclusionDirective()Jan Svoboda1-13/+13
This patch changes type of the `File` parameter in `PPCallbacks::InclusionDirective()` from `const FileEntry *` to `Optional<FileEntryRef>`. With the API change in place, this patch then removes some uses of the deprecated `FileEntry::getName()` (e.g. in `DependencyGraph.cpp` and `ModuleDependencyCollector.cpp`).

2021-04-06[SystemZ][z/OS][Windows] Add new OF_TextWithCRLF flag and use this flag ↵Abhina Sreeskantharajan1-1/+1
instead of OF_Text Problem: On SystemZ we need to open text files in text mode. On Windows, files opened in text mode adds a CRLF '\r\n' which may not be desirable. Solution: This patch adds two new flags - OF_CRLF which indicates that CRLF translation is used. - OF_TextWithCRLF = OF_Text | OF_CRLF indicates that the file is text and uses CRLF translation. Developers should now use either the OF_Text or OF_TextWithCRLF for text files and OF_None for binary files. If the developer doesn't want carriage returns on Windows, they should use OF_Text, if they do want carriage returns on Windows, they should use OF_TextWithCRLF. So this is the behaviour per platform with my patch: z/OS: OF_None: open in binary mode OF_Text : open in text mode OF_TextWithCRLF: open in text mode Windows: OF_None: open file with no carriage return OF_Text: open file with no carriage return OF_TextWithCRLF: open file with carriage return The Major change is in llvm/lib/Support/Windows/Path.inc to only set text mode if the OF_CRLF is set. ``` if (Flags & OF_CRLF) CrtOpenFlags |= _O_TEXT; ``` These following files are the ones that still use OF_Text which I left unchanged. I modified all these except raw_ostream.cpp in recent patches so I know these were previously in Binary mode on Windows. ./llvm/lib/Support/raw_ostream.cpp ./llvm/lib/TableGen/Main.cpp ./llvm/tools/dsymutil/DwarfLinkerForBinary.cpp ./llvm/unittests/Support/Path.cpp ./clang/lib/StaticAnalyzer/Core/HTMLDiagnostics.cpp ./clang/lib/Frontend/CompilerInstance.cpp ./clang/lib/Driver/Driver.cpp ./clang/lib/Driver/ToolChains/Clang.cpp Reviewed By: MaskRay Differential Revision: https://reviews.llvm.org/D99426
2020-01-28Make llvm::StringRef to std::string conversions explicit.Benjamin Kramer1-2/+1
This is how it should've been and brings it more in line with std::string_view. There should be no functional change here. This is mostly mechanical from a custom clang-tidy check, with a lot of manual fixups. It uncovers a lot of minor inefficiencies. This doesn't actually modify StringRef yet, I'll do that in a follow-up.
2019-08-14[Clang] Migrate llvm::make_unique to std::make_uniqueJonas Devlieghere1-1/+1
Now that we've moved to C++14, we no longer need the llvm::make_unique implementation from STLExtras.h. This patch is a mechanical replacement of (hopefully) all the llvm::make_unique instances across the monorepo. Differential revision: https://reviews.llvm.org/D66259 llvm-svn: 368942

2019-01-19Update the file headers across all of the LLVM projects in the monorepoChandler Carruth1-4/+3
to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
