jake 2002/10/27 09:22:44 PST Modified files: sys/sparc64/include utrap.h sys/sparc64/sparc64 exception.S Log: Don peril sensitive sun glasses and change the default system call vector for sparc64 from trap #9 to trap #65. This is one of the ABI "blessed" system call vectors and is different from any other system that we might want to emulate, making the emulation easier by reducing the number of code paths that need to be shared. Compatibility with old applications is provided with COMPAT_FREEBSD4. Add defines for a few special traps that we may need to implement for compatibility with 32bit applications, and add comments on which vectors are used for what in other systems, and which are available. Pass magic flags to trap() for deprecated or unimplemented system call vectors so they will deliver SIGSYS instead of SIGILL. This piggy backs nicely with the recent sigaction(2) system call number change, and provided the rules are followed for upgrading past it, this change should not be noticed.
