jlebar added a comment. The main reason I want this is for CUDA. The way CUDA compilation will work, once I finish my patch, is: For each GPU arch, we compile device code to assembly (ptx) and then assemble the ptx into an object file (cubin). We then pass the cubins *and* ptx files to nVidia's fatbinary program, which "links" them into one blob. We then embed the blob in the host code.
So in this scheme, our Action graph is a DAG: The ptx is used as an input both to the cubin and fatbin actions. Making this DAG work in the absence of this patch is...pretty unpleasant. http://reviews.llvm.org/D15911 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
