-+/* Recognizing signal handler frames. */
-+
-+/* GNU/Linux has two flavors of signals. Normal signal handlers, and
-+ "realtime" (RT) signals. The RT signals can provide additional
-+ information to the signal handler if the SA_SIGINFO flag is set
-+ when establishing a signal handler using `sigaction'. It is not
-+ unlikely that future versions of GNU/Linux will support SA_SIGINFO
-+ for normal signals too. */
-+
-+/* When the SH Linux kernel calls a signal handler and the
-+ SA_RESTORER flag isn't set, the return address points to a bit of
-+ code on the stack. This function returns whether the PC appears to
-+ be within this bit of code.
-+
-+ The instruction sequence for normal signals is
-+ mov.w 1f,r3
-+ trapa #16
-+ or r0, r0
-+ or r0, r0
-+ or r0, r0
-+ or r0, r0
-+ or r0, r0
-+ 1: .word __NR_sigreturn
-+ or 0x9305 0xc310 0x200b 0x200b 0x200b 0x200b 0x200b 0x0077.
-+
-+ Checking for the code sequence should be somewhat reliable, because
-+ the effect is to call the system call sigreturn. This is unlikely
-+ to occur anywhere other than a signal trampoline.
-+
-+ It kind of sucks that we have to read memory from the process in
-+ order to identify a signal trampoline, but there doesn't seem to be
-+ any other way. The PC_IN_SIGTRAMP macro in tm-linux.h arranges to
-+ only call us if no function name could be identified, which should
-+ be the case since the code is on the stack.
-+
-+ Detection of signal trampolines for handlers that set the
-+ SA_RESTORER flag is in general not possible. Unfortunately this is
-+ what the GNU C Library has been doing for quite some time now.
-+ However, as of version 2.1.2, the GNU C Library uses signal
-+ trampolines (named __restore and __restore_rt) that are identical
-+ to the ones used by the kernel. Therefore, these trampolines are
-+ supported too. */
