AArch64: Fix handling of nocancel syscall failures
The current code for nocancel syscalls does not do a comparison of the system call return value. This leads to code being generated where the b.cs follows the svc instruction directly without setting the flags on which the branch depends. ChangeLog: 2014-05-20 Will Newton <will.newton@linaro.org> * sysdeps/unix/sysv/linux/aarch64/nptl/sysdep-cancel.h (PSEUDO): Test the return value of the system call in the nocancel case.
