<pre wrap="" class="moz-quote-pre">This patch adjusts the aforementioned test to use the benchmark
framework introduced before. The default arguments are adjusted
according to the <PARAM_x86.txt> file. The arguments to the script still
can be provided in the command line run.
The benchmark input is given by redirecting the corresponding
<FASTA_5000000> file generated by the `libs/fasta.lua 5e6`. The output
from the benchmark is redirected to /dev/null. Checks are skipped since
the output is very huge, and it is overkill to store it in the
repository.
