Do we have a convention, when do we use "-" and when "."?
Dots are decoded by something (@format, %field, etc).
Dashes are completely ignored.
See "fixedbit_elt" in docs/devel/decodetree.rst.
I plan to add a few instructions which do something with special
registers on OpenSparc, but would be nop in QEMU. Shall I use dots? Or
rather dashes?
That depends on what it is.
