-/* Sigtramp is a routine that the kernel calls (which then calls the
-   signal handler).  On most machines it is a library routine that is
-   linked into the executable.
-  
-   This macro, given a program counter value and the name of the
-   function in which that PC resides (which can be null if the name is
-   not known), returns nonzero if the PC and name show that we are in
-   sigtramp.
-  
-   On most machines just see if the name is sigtramp (and if we have
-   no name, assume we are not in sigtramp).
-  
-   FIXME: cagney/2002-04-21: The function find_pc_partial_function
-   calls find_pc_sect_partial_function() which calls
-   DEPRECATED_PC_IN_SIGTRAMP.  This means DEPRECATED_PC_IN_SIGTRAMP
-   function can't be implemented by doing its own local NAME lookup.
-  
-   FIXME: cagney/2002-04-21: DEPRECATED_PC_IN_SIGTRAMP is something of
-   a mess.  Some code also depends on SIGTRAMP_START and SIGTRAMP_END
-   but other does not.
-  
-   NOTE: cagney/2004-03-16: DEPRECATED_PC_IN_SIGTRAMP has been made
-   obsolete by signal trampoline frame unwind sniffers. */
