Both the optimized and generic versions of __read_pipe function contains call of other library functions and are complicate enough not to be generated programmatically. amdgpu target does not have the capability to link in library code after LLVM codegen. The linking has to be done before SimplifyLibCalls. https://reviews.llvm.org/D36327 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
