Support catch syscall on aarch64 linux
Hi, This patch is to support catch syscall on aarch64 linux. We implement gdbarch method get_syscall_number for aarch64-linux, and add aarch64-linux.xml file, which looks straightforward, however the changes to test case doesn't. First of all, we enable catch-syscall.exp on aarch64-linux target, but skip the multi_arch testing on current stage. I plan to touch multi arch debugging on aarch64-linux later. Then, when I run catch-syscall.exp on aarch64-linux, gcc errors that SYS_pipe isn't defined. We find that aarch64 kernel only has pipe2 syscall and libc already convert pipe to pipe2. As a result, I change catch-syscall.c to use SYS_pipe if it is defined, otherwise use SYS_pipe2 instead. The vector all_syscalls in catch-syscall.exp can't be pre-determined, so I add a new proc setup_all_syscalls to fill it, according to the availability of SYS_pipe. Regression tested on {x86_64, aarch64}-linux x {native, gdbserver}. gdb: 2015-03-18 Yao Qi <yao.qi@linaro.org> PR tdep/18107 * aarch64-linux-tdep.c: Include xml-syscall.h (aarch64_linux_get_syscall_number): New function.
