Modify the emulated system calls to support running the SPEC Int
benchmarks for alpha-linux. arch/alpha/alpha_linux_process.cc: Added some more ioctl commands to ignore. Set unlink and rename to the new functions. Ignore setrlimit, times and rt_sigaction. Should eventually provide a function for times. arch/alpha/alpha_tru64_process.cc: Added some more ioctl commands to ignore. Set unlink and rename to the new functions. Ignore setrlimit. sim/syscall_emul.cc: Added implementations for unlink and rename. sim/syscall_emul.hh: Added unlink and rename functions. Added a couple more ioctl requests to ignore. Print out the PC of any ioctl commands that fail. --HG-- extra : convert_revision : 8af21c7fa7d0645d3f9324c9ce70ad33590c3c8e
