- Check names of system calls (for special treatment) because emulations might use different numbers. - Report an error if arguments to -p or -m non-numeric. - Just take last of -x and -Xvalue, stop -X0x80000000 being valid (core dumps). - Keep 'last used' emulation_ctx at top of list, create on lookup (usually EMUL anyway), delete when exit called (doesn't return). - Slightly improve hack to get correct system call name in execve return when emulation has changed. - Rename global variables 'current'/'previous' to 'cur_emul'/'prev_emul'. (TODO: save system call type (and maybe an argument) per pid so GIO trace format can depend on the actual system call.) Fixes part of PR sparc64/23473 - but system call arguments will still not be displayed correctly.
