[PATCH] Add support for ARC architecture (Synopsys)

Vineet Gupta Vineet.Gupta1 at synopsys.com
Tue Mar 15 12:28:40 UTC 2011


From: Vineet Gupta <vgupta at synopsys.com>

* configure.ac: Add ARC architecture
* defs.h: Define TCB_WAITEXECVE for ARC
* linux/arc/syscall.h: ARC specific new file
* Makefile.am: Add linux/arc/syscall.h
* process.c (change_syscall, struct_user_offsets): Add ARC support
* syscall.c (get_scno, get_error, syscall_enter): Likewise.
* signal.c (sys_sigreturn): Add ARC support
