It would certainly be possible to do the same thing in objdump, and FWIW, I did wonder about that when adding the readelf -A GOT dump. The problem is that, in a multi-GOT world, the annotations are only ever going to be a best guess. If the disassembler sees:
lw $2,-32000(gp)
it doesn't in general know whether gp points to the primary (ABI-defined) GOT, or to some secondary GOT. If it guesses right, the annotation would be useful, but if it guesses wrong, the annotation would be very misleading. This is different from the current<foo> markers, which are always accurate (or at least, _should_ always be accurate).
Can the GOT pointer switch between GOTs within a single function?
No.
I suppose it should be moderately easy to decode the prologue of each function then to see which GOT $gp refers to.
