Use std::nullopt_t instead of NoneType (NFC) 2022-11-23T22:16:04+00:00 Kazu Hirata kazu@google.com 2022-11-23T22:16:04+00:00 34bcadc38c2240807cd079fd03b93fc96cf64c84 This patch replaces those occurrences of NoneType that would trigger an error if the definition of NoneType were missing in None.h. To keep this patch focused, I am deliberately not replacing None with std::nullopt in this patch or updating comments. They will be addressed in subsequent patches.

Update the file headers across all of the LLVM projects in the monorepo 2019-01-19T08:50:56+00:00 Chandler Carruth chandlerc@gmail.com 2019-01-19T08:50:56+00:00 2946cd701067404b99c39fb29dc9c74bd7193eb3 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

[ADT] Add streaming operators for llvm::Optional 2019-01-18T12:52:03+00:00 Pavel Labath pavel@labath.sk 2019-01-18T12:52:03+00:00 47e9a21d34849b52bbde557f3aacca2941f34092 Summary: The operators simply print the underlying value or "None". The trickier part of this patch is making sure the streaming operators work even in unit tests (which was my primary motivation, though I can also see them being useful elsewhere). Since the stream operator was a template, implicit conversions did not kick in, and our gtest glue code was explicitly introducing an implicit conversion to make sure other implicit conversions do not kick in :P. I resolve that by specializing llvm_gtest::StreamSwitch for llvm:Optional<T>.
