[Mlir-commits] [mlir] [MLIR] Add missing analysis_gen dependency to ExecutionEngine targets (PR #186936)

https://github.com/tmimmanuel created https://github.com/llvm/llvm-project/pull/186936

Fixes #186867.

`MLIRExecutionEngineUtils` and `MLIRExecutionEngine` both include headers that transitively require the generated file `TargetLibraryInfo.inc` (`OptUtils.cpp` → `PassBuilder.h` → `CGSCCPassManager.h` → `LazyCallGraph.h` → `TargetLibraryInfo.h` → `TargetLibraryInfo.inc`).

This file is produced by the `analysis_gen` tablegen target defined in `llvm/include/llvm/Analysis/CMakeLists.txt`. Both MLIR targets declared `LINK_COMPONENTS Analysis` and `DEPENDS intrinsics_gen`, but were missing `analysis_gen`. Because `LINK_COMPONENTS` only affects linking and does not create build-order dependencies on tablegen targets, parallel builds
can attempt to compile `OptUtils.cpp` before `TargetLibraryInfo.inc` exists.

This patch adds `analysis_gen` to the `DEPENDS` list of both targets, matching how `LLVMAnalysis` itself declares this dependency in `llvm/lib/Analysis/CMakeLists.txt`. Other MLIR targets that include Analysis headers (e.g. `MLIRTargetLLVM`) link against
`MLIRExecutionEngineUtils` and inherit the build-order dependency transitively.

Verified with a clean build of `MLIRExecutionEngineUtils` after removing the generated `.inc` file — the build succeeds with the fix applied.
