The only versions of the Solaris assembler I have access to only support
v8plusX according to the man page. Has that changed recently?

sparc4 sounds very 1990-ish...

What's the relationship between VIS4 and SPARC-T4 exactly? The above manual
only speaks of VIS3 as far as I can see. And the CBcond instructions are not
marked as belonging to VIS (3 or 4), so using -mvis4 for them seems strange.
Why not make them depend on -mcpu=niagara4 instead?
