# Makefile for benchmark tests. The only useful target here is `bench`.
|
|
|
|
# Adding a new function `foo`:
|
|
# ---------------------------
|
|
|
|
# - Append the function name to the bench variable
|
|
|
|
# - Define foo-ITER with the number of iterations you want to run. Keep it
|
|
# high enough that the overhead of clock_gettime is only a small fraction of
|
|
# the total run time of the test.
|
|
|
|
# - Define foo-ARGLIST as a colon separated list of types of the input
|
|
# arguments. Use `void` if function does not take any inputs. Put in quotes
|
|
# if the input argument is a pointer, e.g.:
|
|
|
|
# malloc-ARGLIST: "void *"
|
|
|
|
# - Define foo-RET as the type the function returns. Skip if the function
|
|
# returns void. One could even skip foo-ARGLIST if the function does not
|
|
# take any inputs AND the function returns void.
|
|
|
|
|
|
# - Make a file called `foo-inputs` with one input value per line, an input
|
|
# being a comma separated list of arguments to be passed into the function.
|
|
# See pow-inputs for an example.
