Hi, Please find attached a patch that adds syscall.h file into the CR16 libgloss folder. This patch is in conjunction with a corresponding patch to the sim. The build failures as logged in this bug report have already been fixed, however the correct newlib syscalls are not being used. http://sourceware.org/bugzilla/show_bug.cgi?id=12862 This patch should allow the regeneration of a correct nltvals.def file which in turn should allow correct functioning of cr16-elf-run. I'll be posting the sim patch to gdb-patches shortly. The syscall definitions are in line with the original CR16 simulator patch submitted in 2008, http://sourceware.org/ml/gdb/2008-02/msg00108.html However, later changes in gdb-sim broke the cr16 build as the cr16 list in the nltvals.def file were probably hand tweaked. Kindly review the attached patch and let me know if these changes are OK. 2012-08-24 Kaushik Phatak <kaushik.phatak@kpitcummins.com> * libgloss/cr16/sys/syscall.h New.
