GCC 5.1 is the first release of that, GCC 5.2 the second, etc. Everyone should always use an as new release as practical, since many bugs will be fixed, and nothing else changed. See . So, this means everyone using GCC 5 should be using the GCC 5.5 release! If there is something about 5.1 that makes it produce bad kernels on some arch, make that arch's Makefile complain? Same with binutils etc. Segher _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv
