Add support for generating a systemtap tapset static probes
This introduces generation of a qemu.stp/qemu-system-XXX.stp
files which provides tapsets with friendly names for static
probes & their arguments. Instead of
probe process("qemu").mark("qemu_malloc") {
printf("Malloc %d %p\n", $arg1, $arg2);
}
It is now possible todo
probe qemu.system.i386.qemu_malloc {
printf("Malloc %d %p\n", size, ptr);
}
There is one tapset defined per target arch, for both
user and system emulators.
* Makefile.target: Generate stp files for each target
* tracetool: Support for generating systemtap tapsets
* configure: Check for whether systemtap is available
with the DTrace backend
