mips.h (TARGET_SWITCHES, TARGET_OPTIONS): Add option doc strings.


I have checked in this patch.  This fixes some compile time warning messages
about missing initializers by adding documentation for MIPS specific options.

Mon Mar 22 18:06:59 1999  Jim Wilson  <wilson@cygnus.com>

	* mips.h (TARGET_SWITCHES, TARGET_OPTIONS): Add option doc strings.
	* abi64.h (SUBTARGET_TARGET_OPTIONS): Likewise.
