And bug63510 can be closed. :-) So for me, we need not spend additional time resources on it. I shall continue to other issues in gcc or qemu. Now, I guess, my 1st priority is to rewrite tilegx qemu floating point insns within 2015-10-31. Welcome additional ideas, suggestions, and completions. Thanks.
