From 95c248c2139ff8d3568e1c92319727777f19920f Mon Sep 17 00:00:00 2001 From: David Oehmke Date: Thu, 5 Feb 2004 12:16:17 -0500 Subject: 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 --- sim/syscall_emul.cc | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) (limited to 'sim/syscall_emul.cc') diff --git a/sim/syscall_emul.cc b/sim/syscall_emul.cc index 9955d4421..e953a7308 100644 --- a/sim/syscall_emul.cc +++ b/sim/syscall_emul.cc @@ -185,4 +185,32 @@ gethostnameFunc(SyscallDesc *desc, int num, Process *p, ExecContext *xc) return 0; } +int +unlinkFunc(SyscallDesc *desc, int num, Process *p, ExecContext *xc) +{ + std::string path; + + if (xc->mem->readString(path, xc->getSyscallArg(0)) != No_Fault) + return -EFAULT; + + int result = unlink(path.c_str()); + return (result == -1) ? -errno : result; +} + +int +renameFunc(SyscallDesc *desc, int num, Process *p, ExecContext *xc) +{ + std::string old_name; + + if (xc->mem->readString(old_name, xc->getSyscallArg(0)) != No_Fault) + return -EFAULT; + + std::string new_name; + + if (xc->mem->readString(new_name, xc->getSyscallArg(1)) != No_Fault) + return -EFAULT; + + int result = rename(old_name.c_str(),new_name.c_str()); + return (result == -1) ? -errno : result; +} -- cgit v1.2.3
