A flag in struct proc determines whether the process expects an old sigframe or a new sigframe. The signal trampoline handles which sigreturn to call. It does this by testing for a magic cookie in the frame. The alpha uses osigreturn to implement longjmp. This means that osigreturn is not only used for compatibility with existing binaries. To handle the new sigset_t, setjmp saves it in sc_reserved (see NOTE). the struct sigframe has been moved from frame.h to sigframe.h to handle the complex header dependencies that was caused by the new sigframe. NOTE: For the i386, the size of jmp_buf has been increased to hold the new sigset_t. On the alpha this has been prevented by using sc_reserved in sigcontext.
