gdb: Add sparc*-*-linux catch syscall support.
2010-02-24 David S. Miller <davem@davemloft.net>
* gdb_ptrace.h (PT_SYSCALL): If PTRACE_SYSCALL is available, use it.
* syscalls/sparc-linux.xml: New.
* syscalls/sparc64-linux.xml: New.
* Makefile.in (XML_SYSCALL_FILES): Add new syscall XML files.
* sparc-linux-tdep.c (XML_SYSCALL_FILENAME_SPARC32): Define.
(sparc32_linux_get_syscall_number): New function.
(sparc32_linux_init_abi): Set syscall XML file name and hook up
syscall number fetcher.
* sparc64-linux-tdep.c (XML_SYSCALL_FILENAME_SPARC64): Define.
(sparc64_linux_get_syscall_number): New function.
(sparc64_linux_init_abi): Set syscall XML file name and hook up
