  We provide asymptotic formulas for the Bergman projector and Berezin-Toeplitz
operators on a compact K{\"a}hler manifold. These objects depend on an integer
N and we study, in the limit N $\rightarrow$ +$\infty$, situations in which one
can control them up to an error O(e^{-cN}) for some c > 0. We develop a
calculus of Toeplitz operators with real-analytic symbols, which applies to
K{\"a}hler man-ifolds with real-analytic metrics. In particular, we prove that
the Bergman kernel is controlled up to O(e^{-cN}) on any real-analytic
K{\"a}hler manifold as N $\rightarrow$ +$\infty$. We also prove that Toeplitz
operators with analytic symbols can be composed and inverted up to O(e^{-cN}).
As an application, we study eigenfunction concentration for Toeplitz operators
if both the manifold and the symbol are real-analytic. In this case we prove
exponential decay in the classically forbidden region.
