I think on the alpha that value is constant.  (Though it does strike me
as possible that, as on the sparc, the assembler sometimes generates
multiple instructions for what looks like a single instruction in the
assembly code.)

That looks to me a lot more like x86 assembly.  The x86 _does_ have
variable-size instructions, reinforcing this notion.  You'd probably
have better results asking on port-i386 than port-alpha.
