This patch allows one to provide the function name using an optional
-base option to compare all other functions against. This is useful
when pitching one implementation of a string function against
alternatives. In the absence of this option, comparisons are done
against the first ifunc in the list.
* benchtests/scripts/compare_strings.py (main): Add an
optional -base option.
(process_results): New argument base_func.
Read the memcpy results in json and print out the results in tabular
form, in addition to generating a graph of the results to compare all
of the implementations.
The format of the output is extensible enough to allow this kind of
analysis to be done on other string functions as well.
* benchtests/scripts/benchout_strings.schema.json: New file.
* benchtests/scripts/compare_strings.py: New file.
