flang] Remove remaining uses of llvm::Optional (NFC)

2023-01-08T06:32:38+00:00

This patch removes the unused "using" declaration and removes #include
"llvm/ADT/Optional.h".

This is part of an effort to migrate from llvm::Optional to
std::optional:

[flang] Use std::optional instead of llvm::Optional (NFC)

2023-01-08T06:26:48+00:00

This patch replaces (llvm::|)Optional< with std::optional<.  I'll post
a separate patch to remove #include "llvm/ADT/Optional.h".

[flang] Add #include (NFC)

2023-01-08T04:55:47+00:00

This patch adds #include  to those files containing
llvm::Optional<...> or Optional<...>.

I'll post a separate patch to actually replace llvm::Optional with
std::optional.

[mlir:NFC] Remove the forward declaration of FuncOp in the mlir namespace

2022-04-18T19:01:55+00:00

FuncOp has been moved to the `func` namespace for a little over a month, the
using directive can be dropped now.

[flang] Remove 'using namespace mlir;` from header files

2022-03-09T10:19:51+00:00

Currently, CGOps.h and FIROps.h contain `using namespace mlir;`. Every
file that includes one of these header files (directly and transitively)
will have the MLIR namespace enabled. With name-clashes within
sub-projects (LLVM and MLIR, MLIR and Flang), this is not desired. Also,
it is not possible to "un-use" a namespace once it is "used". Instead,
we should try to limit `using namespace` to implementation files (i.e.
*.cpp).

This patch removes `using namespace mlir;` from header files and adjusts
other files accordingly. In header and TableGen files, extra namespace
qualifier is added when referring to symbols defined in MLIR. Similar
approach is adopted in source files that didn't require many changes. In
files that would require a lot of changes, `using namespace mlir;` is
added instead.

[mlir] Rename the Standard dialect to the Func dialect

2022-03-01T20:10:04+00:00

The last remaining operations in the standard dialect all revolve around
FuncOp/function related constructs. This patch simply handles the initial
renaming (which by itself is already huge), but there are a large number
of cleanups unlocked/necessary afterwards:

* Removing a bunch of unnecessary dependencies on Func
* Cleaning up the From/ToStandard conversion passes
* Preparing for the move of FuncOp to the Func dialect
