Enable the MLIR LLVM project in the clang folder so the compiler flow can use MLIR and TOSA APIs that are not provided by a plain LLVM build.
Add a patch that fix the install targets for mlir-src-sharder and mlir-irdl-to-cpp. Signed-off-by: Luca Fancellu <[email protected]> --- ...l-helper-tools-used-by-CMake-exports.patch | 59 +++++++++++++++++ meta/recipes-devtools/clang/common.inc | 1 + meta/recipes-devtools/clang/llvm-mlir_git.bb | 66 +++++++++++++++++++ 3 files changed, 126 insertions(+) create mode 100644 meta/recipes-devtools/clang/clang/0042-MLIR-Install-helper-tools-used-by-CMake-exports.patch create mode 100644 meta/recipes-devtools/clang/llvm-mlir_git.bb diff --git a/meta/recipes-devtools/clang/clang/0042-MLIR-Install-helper-tools-used-by-CMake-exports.patch b/meta/recipes-devtools/clang/clang/0042-MLIR-Install-helper-tools-used-by-CMake-exports.patch new file mode 100644 index 000000000000..6079e61c9cc2 --- /dev/null +++ b/meta/recipes-devtools/clang/clang/0042-MLIR-Install-helper-tools-used-by-CMake-exports.patch @@ -0,0 +1,59 @@ +From e5f6551510eb2adb1fffe9564965101e05ca9720 Mon Sep 17 00:00:00 2001 +From: Momchil Velikov <[email protected]> +Date: Fri, 19 Jun 2026 18:00:51 +0000 +Subject: [PATCH] [MLIR] Install missing standalone helper tools + +Standalone MLIR installs CMake package files that can reference helper +executables needed by downstream builds.
