Kazu Hirata	63b63c3dcd	[flang/unittests] 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	2022-12-03 19:08:01 -08:00
Jean Perier	a398981fb0	[flang] Add fir.declare operation ... Add fir.declare operation whose purpose was described in https://reviews.llvm.org/D134285. It uses the FortranVariableInterfaceOp for most of its logic (including the verifier). The rational is that all these aspects/logic will be shared by hlfir.designate and hlfir.associate. Its codegen and lowering will be added in later patches. Differential Revision: https://reviews.llvm.org/D136181	2022-10-19 11:06:58 +02:00
