Assembling AND $7, R1 gives:

addpool: ADDCON0 in 00000 (/opt/opensource/gopath/src/andimm/amovdu.s:2) AND $7, R1 shouldn't go to default case

Assembling AND $~7, R1 works, but loads the constant from the constant pool.

Turns out the former is just a warning, not a failure, and this is all related to #10111 (and a long argument on https://go-review.googlesource.com/7046 )
