[LLVMdev] SparcV9 casa instruction

[Reid Spencer]

Brent,

A little googling found this:

http://onesearch.sun.com/search/clickthru?qt=%2Bcasa+SPARC+instruction&url=http%3A%2F%2Fdevelopers.sun.com%2Fsolaris%2Farticles%2Fsparcv9.pdf&pathInfo=%2Fonesearch%2Findex.jsp&hitNum=1&col=all

Its a pdf with the complete SPARC v9 instruction set details. What you
want is on page 152.
