1) There is no description of what machine modes are. Even a reference to the
internals manual would be enough.
2) The manual's output lists function attributes, /then/ attribute syntax, then
some completely unrelated stuff, then type attributes. These sections should be
rearranged in the texinfo source.
I plan on doing this sometime before I die, but wanted an open bug to remind me.
It's assigned to me, but anybody should feel free to beat me to it.

* extend.texi (Common Variable Attributes): Add xref to GCC
Internals manual to explain mode attribute keywords.
Problem (1) now fixed for GCC 7.
Problem (2) has already been fixed by one of my previous organization changes; now all the attribute-related sections are grouped together.
