URL: https://github.com/llvm/llvm-project/commit/46846ac45b2c44aa6e33be5ac498309f465ba7eb DIFF: https://github.com/llvm/llvm-project/commit/46846ac45b2c44aa6e33be5ac498309f465ba7eb.diff LOG: [Matrix] Add inline assembly test case. This patch adds a new test cases which uses a matrix value as memory inline assembly argument. Currently the pointer element type does not match the vector type.
