Information on SPARC assembly (atomic Test and Set)

[Rich Patterson]

Hi,
	I need some help in finding information on coding atmoic bit
operations on a Sun-4 (SPARC).  I wasn't able to find a reference to a
"Test and Set" operation in the Assembly guide that comes with our Sun-4.
	Are there any other references on SPARC assembly, Sun published or
otherwise ?  Any help or code would be appreciated.  Please e-mail to the
address below.

Thanks,
Rich P.
