--- Comment #38 from Dominik Vogt <vogt at linux dot vnet.ibm.com> ---
Finally, the total between after the last and before the first patch. Overall,
some tests gain some performance and others lose some. The total number of
instructions has grown somewhat (especially tonto, calculix, dealII and wrf),
but there's no obvious connection between an increased number of instructions
and loss of performance.
Is this what can be expected of the patches?
All compiled with -O3 -funroll-loops -march=zEC12.
