[Joseph S. Myers]

PR other/1078 lists problems with the documentation of various attributes.  
The following is an update to the list there:

init_priority is now documented.

The SH attributes interrupt_handler, sp_switch and trap_exit are now
documented.

The ARM attribute interfacearm, not on the previous list, is undocumented.

The stormy16 attribute interrupt is not documented.

Could the ARC, ARM, AVR, C4X, H8/300, IA64, i386, m68hc11, MCore, ns32k,
stormy16 and V850 maintainers update the documentation in extend.texi
relating to their targets' attributes?
