Is there any way to time some code that is inside a parfor that is inside a function I'm trying to convert to mex via the Coder Toolbox?

function [outputs] = to_be_mexed(inputs)

parfor i = 1:100

tic;

hard_stuff;

toc;

end

tic and toc are not supported for code generation (same for clock and seemingly all other built-ins for timing), and, if I use coder.extrinsic, that ordinarily works, but apparently is not allowed within a parfor inside a mex function. Any way to time stuff here? Can be very crude, +/- a few seconds would be more than fine.
