you'd need to experiment with -O2, -O3 etc ;)
the joke is at -O100 we'd beat the fastest supercomputer, i.e. it doesn't't do anything :lol:

Dhrystone is a synthetic computing benchmark program developed in 1984 by Reinhold P. Weicker intended to be representative of system programming. The Dhrystone grew to become representative of general processor performance.

The name "Dhrystone" is a pun on a different benchmark algorithm called Whetstone, which emphasizes floating point performance.

With Dhrystone, Weicker gathered meta-data from a broad range of software, including programs written in FORTRAN, PL/1, SAL, ALGOL 68, and Pascal.

He then characterized these programs in terms of various common constructs: procedure calls, pointer indirections, assignments, etc. From this he wrote the Dhrystone benchmark to correspond to a representative mix.

Dhrystone was published in Ada, with the C version for Unix developed by Rick Richardson greatly contributing to its popularity.

I do not understand that piece of code. Simply enable the ART and that's it. The Chrom-ART is not available on all devices - but that is about DMA blobs manipulation.

the only difference between a m4 & a m7 is m4 = 3 stage pipeline & m7 = 6 stage pipeline.
