https://github.com/llvm/clangir/issues/1025 discusses the motivation.
The mechanical parts of this change were done via:
find clang \( -name '*.h' -o -name '*.cpp' -o -name '*.td' \) -print0 |
xargs -0 perl -pi -e 's/mlir::cir/cir/g'
find clang \( -name '*.h' -o -name '*.cpp' \) -print0 | xargs -0 perl
-pi -e 's/::cir/cir/g'
There were some manual fixups and a clang-format run afterwards.
Finish hooking up ClangIR code gen into the Clang control flow,
initializing enough that basic code gen is possible.
Add an almost empty `cir.func` op to the ClangIR dialect. Currently the
only property of the function is its name. Add the code necessary to
code gen a cir.func op.
Create essentially empty files
clang/lib/CIR/Dialect/IR/{CIRAttrs.cpp,CIRTypes.cpp}. These will be
filled in later as attributes and types are defined in the ClangIR
dialect.
(Part of upstreaming the ClangIR incubator project into LLVM.)
This adds no real content, it just incrementally adds some scaffolding
necessary to enable a future patch to just add our first few ops.
Test Plan:
```
$ cmake -Sllvm -Bbuild -DCLANG_ENABLE_CIR=1 \
-DLLVM_ENABLE_PROJECTS='clang;mlir' \
-DCMAKE_BUILD_TYPE=Release -GNinja
$ ninja -C build check-clang
$ ninja -C build MLIRCIROpsIncGen
$ ninja -C build MLIRCIR
```
