-/* Under GNU/Linux, signal handler invocations can be identified by
-   the designated code sequence that is used to return from a signal
-   handler.  In particular, the return address of a signal handler
-   points to a sequence that copies $sp to $16, loads $0 with the
-   appropriate syscall number, and finally enters the kernel.
-
-   This is somewhat complicated in that:
-     (1) the expansion of the "mov" assembler macro has changed over
-         time, from "bis src,src,dst" to "bis zero,src,dst",
-     (2) the kernel has changed from using "addq" to "lda" to load the
-         syscall number,
-     (3) there is a "normal" sigreturn and an "rt" sigreturn which
-         has a different stack layout.
