extern void waitevent(struct trussinfo *);
It turns out that truss also used kdump's mkioctls script, and expected ioctlname() to return a pointer to the name rather than print it. This did not show up in testing because truss had its own prototype for ioctlname(), so it would build fine and run fine as long as the program being traced did not issue an ioctl. Teach mkioctls to generate different versions of ioctlname() based on its first command-line argument. Pointed out by: Garrett Cooper <yanegomi@gmail.com>

Teach truss about 32-bit FreeBSD and Linux binaries on amd64. Some additional work is needed to handle ABI-specific syscall argument parsing, but this gets the basic tracing working. MFC after: 1 week

extern void i386_syscall_entry(struct trussinfo *, int);
Port truss(1) to 64-bit architectures: o Syscall return values do not fit in int on 64-bit architectures. Change the type of retval in <arch>_syscall_exit() to long and change the prototype of said function to return a long as well. o Change the prototype of print_syscall_ret() to take a long for the return address and change the format string accordingly. o Replace the code sequence tmp = malloc(X); sprintf(tmp, format, ...); with X by definition too small on 64-bit platforms by asprintf(&tmp, format, ...); With these changes the output makes sense again, although it does mess up the tabulation on ia64. Go widescreen... Not tested on: alpha, sparc64.
