  "message": "[Bazel] Move HAL materializeConstant to break IR/HALDialect circular dependency (#24203)\n\nThe previous IREE has a hidden circular reference at link time:\n```\n:HALDialect --depends on--\u003e :IR\n:IR (vtable in HALAttrs.o) --references--\u003e :HALDialect (materializeConstant in HALDialect.o)\n```\nThis becomes a problem for build targets that intend to depend only on\n`:IR`:\n1. They must add `:HALDialect` to Bazel deps to resolve:\n```\ncmake linker error: undefined symbol: mlir::iree_compiler::IREE::HAL::HALDialect::materializeConstant(mlir::OpBuilder\u0026, mlir::Attribute, mlir::Type, mlir::Location)\n\u003e\u003e\u003e referenced by HALAttrs.cpp\n\u003e\u003e\u003e               lib/libiree_compiler_Dialect_HAL_IR_IR.a(lib/../compiler/src/iree/compiler/Dialect/HAL/IR/CMakeFiles/iree_compiler_Dialect_HAL_IR_IR.objects.dir/HALAttrs.cpp.o)\n```\n2. Bazel then sorted `:HALDialect` before `:IR` and result in:\n```\nld.lld: error: backward reference detected: _ZN4mlir13iree_compiler4IREE3HAL10HALDialect19materializeConstantERNS_9OpBuilderENS_9AttributeENS_4TypeENS_8LocationE in bazel-out/k8-opt/bin/compiler/src/iree/compiler/Dialect/HAL/IR/_objs/IR/HALAttrs.pic.o refers to bazel-out/k8-opt/bin/compiler/src/iree/compiler/Dialect/HAL/IR/_objs/HALDialect/HALDialect.pic.o\n```\n\nThis PR moves `materializeConstant` to `HALAttrs.cpp`, which is included\nin `:IR` srcs, breaking the reference cycle.\n\n---------\n\nCo-authored-by: Bangtian Liu \u003cliubangtian@gmail.com\u003e",
