--- Comment #16 from bin.cheng <amker.cheng at gmail dot com> --- I fixed the reported problem and posted new patch at http://gcc.gnu.org/ml/gcc-patches/2013-12/msg01159.html Apology that I missed java in bootstrap for previous patch. This version passes bootstrap and test for c,c++,lto,fortran,java,go,objc,obj_c++ on x86_64. I am not sure if the java case is covered by bootstrap, or other applications. If it's in other application, could anyone help verifying that the issue is addressed on apple-darwin? Thanks.
