This depends on whether you really have an upbeat (f.e. Scherzo ends 
with full measure, Trio starts with upbeat) or an "incomplete" measure 
(f.e. if you have bars of different length whithout explicitely changing 
the time signature; see last of Rachmaninov's Etudes-Tableaux). Have a 
look at the output of the following code. Three different solutions show 
three different types of behaviour (look at bar lines and bar numbers).

\version "2.18.2"

{
        \override Score.BarNumber.break-visibility = #'#(#t #t #t)

        b4 b b b
        b b b \set Timing.measurePosition = #(ly:make-moment 4/4)
        \mark "missing barline"
        b b b b
        \break

        b b b b
	\set Timing.measureLength = #(ly:make-moment 3/4) b b b \unset 
Timing.measureLength
        \mark "everything ok (if it's an 'incomplete' measure)"
        b b b b
        \break

        b b b b
        \partial 4*3
        b b b
        \mark "m. 8 counts twice (ok if it's really an upbeat)"
        b b b b
}
