  "message": "[OpenCL] Add clang internal extension __cl_clang_function_scope_local_variables  (#176726)\n\nOpenCL spec restricts that variable in local address space can only be\ndeclared at kernel function scope.\nAdd a Clang internal extension __cl_clang_function_scope_local_variables\nto lift the restriction.\n\nTo expose static local allocations at kernel scope, targets can either\nforce-inline non-kernel functions that declare local memory or pass a\nkernel-allocated local buffer to those functions via an implicit argument.\n\nMotivation: support local memory allocation in libclc\u0027s implementation\nof work-group collective built-ins, see example at:\nhttps://github.com/intel/llvm/blob/41455e305117/libclc/libspirv/lib/amdgcn-amdhsa/group/collectives_helpers.ll\nhttps://github.com/intel/llvm/blob/41455e305117/libclc/libspirv/lib/amdgcn-amdhsa/group/collectives.cl#L182\n\nRight now this is a Clang-only OpenCL extension intended for compiling\nOpenCL libraries with Clang. It could be proposed as a standard OpenCL\nextension in the future.",
