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.
I hope I didn't use any other of these "improved" mnenomics. The lzd
comment is in about a 3 point font, so I am bound to have missed such
comments about any other instructions.
They messed about with add and sub, deprecating addx and subx, I suppose
these are less harmful, snce they added lots of new instructions in that
area anyway. I doubt I use addx or its new spelling.
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
Aren't you using your latest assembler? :-)
(Else, you'd not have struck the lzcnt v2 issue...)
