CodeSourcery is working on improving performance for Intel's Core 2 and
Core i7 families of processors.
CodeSourcery plans to add support for unaligned vector instructions, to
provide fine-tuned scheduling support and to update instruction
selection and instruction cost models for Core i7 and Core 2 families of
processors.
As usual, CodeSourcery will be contributing its work to GCC. Currently,
our target is the end of GCC 4.6 Stage1.
If your favorite benchmark significantly under-performs on Core 2 or
Core i7 CPUs, don't hesitate asking us to take a l...@it.
We appreciate Intel sponsoring this project.
Maxim,
Do you have any updates on the progress of this project? Since
it has been proposed to default intel darwin to -mtune=core2, it
would be very helpful to be able to test (benchmark) any proposed
changes on x86_64-apple-darwin10 with gcc trunk. Thanks in advance.
Jack,
We will start posting patches very soon. Bernd Schmidt has almost
finished pipeline model for Core 2/i7, so that will be the first piece
of work we'll post for upstream review.
Regards,
