Well you can save more in the total size if the constant is needed in more than one place in the application (and linker can merge the CP entries) but I see your point about possible cache miss. It's not a clear win, as you say.

Wouldn't it better to put more complicated constants (requiring 4 and more instructions to materialize) in constant pool and load them from there?
