In our manual (info "(auctex)Development") or

Almost: if nothing is changed the viewer is opened.  C-c C-u (or the
new key binding, in case we should change it) basically is like
running C-c C-c repeatedly but without being prompted every time.  The
default option is always used.  You issue C-c C-u and the document
will be compiled until it's ready, but remember AUCTeX' mechanism to
guess the next command is far from being bullet-proof.

The function `TeX-command-sequence', on which `TeX-update' (or its new
name, in case we should change it) is based, can be fed with a list of
string: if you happen to frequently run the same list of commands,
e.g. LaTeX - BibTeX - LaTeX - LaTeX - View, you can bind a key to the
following lambda:

    (lambda ()
      (interactive)
      (TeX-command-sequence '("LaTeX" "BibTeX" "LaTeX" "LaTeX" "View") t))

This is like a simple Makefile.  You can also give
`TeX-command-sequence' as argument another function if you don't like
`TeX-command-default''s logic to guess the default command.

You're welcome!
