For the fmpyadd instruction on the hppa architecture, there is a bit

register. However, according to page 6-57 of the PA-RISC 1.1 Architecture

Annoyingly, page 6-57 doesn't actually mention the interpretation of the f bit at all.
However, I can see how the H specifier is processed in gas, and the confirmation of glibc
fixes is nice.
