/* _UC_MACHINE_SP is a platform independent macro.
   Defined in <machine/mcontext.h>, see
     http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/$arch/include/mcontext.h
   Supported on alpha, amd64, i386, ia64, m68k, mips, powerpc, sparc since
   NetBSD 2.0.
   On i386, _UC_MACHINE_SP is the same as ->uc_mcontext.__gregs[_REG_UESP],
   and apparently the same value as       ->uc_mcontext.__gregs[_REG_ESP]. */
