I'm just annoyed a bit only because I work pretty consistently to give
you full feedback when you ask for testing within 24 hours.  And this
includes weekends and holidays.

Why it is such a big deal to simply wait until you get the feedback,
what's the rush? :-)

Oracle specifies a lot of impractical deprecations of existing
mnenomics in the UA2011 manual.  For example, they also want to phase
out "ldd" for integer registers and start to call it "ldtwa".  I wish
them a lot of luck with that.

Besides, the manual can say whatever it wants, it's what the assembler
accepts that matters, right? :-)

BTW, I added support for all of the VIS3 instructions to binutils in
2011, so build testing ought to not be that hard even on pre-T3
