[Mlir-commits] [mlir] [MLIR][build] Fix undefined references in debug shared libs (#189206) (PR #189207)

[llvmlistbot at llvm.org]

https://github.com/dwrank created https://github.com/llvm/llvm-project/pull/189207

Fixes undefined references in debug shared libs when building MLIR:
-DLLVM_ENABLE_PROJECTS="mlir"
-DCMAKE_BUILD_TYPE=Debug
-DBUILD_SHARED_LIBS=1

Debug build (-O0) disables dead code elimination, resulting in undefined references in the following shared libs:

MLIROpenMPDialect (needs to link with TargetParser)
MLIRXeVMDialect (needs to link with TargetParser and MLIROpenMPDialect)
MLIRNVVMDialect (needs to link with TargetParser and MLIROpenMPDialect)
