Attached are two more files which should be included in the Broadwell
directory. They should also be faster on Skylake, though Skylake will
automatically look in there.
I don't think they can work on Haswell, but this could be checked.
Also, I forgot one step in the above post:
* Make a tuning

For a release, we need to fix a performance issue noted by Marcel Keller.
It shows up on Ivy Bridge when linking against MPIR with pthreads vs
without (yes it's very strange).
A program used by Marcel to get timings is attached.
Also attached are addmul_1.asm by Jens Nurmann, which tries to fix
It's Haswells and Broadwells that may not support BMI2. Note that we now
occasionally encounter such machines.

The following would be important tickets to resolve before updating the
GMP_VERSION to 6.1.0 (or releasing MPIR-3.0.0). Otherwise we should do a
2.8.0 instead.

There's a list of other tickets marked for a 2.8.0

In terms of work that needs to be done from a Windows perspective:
1. I have added two new functions to the MPIR API (as discussed
recently) and I need to offer documentation for these to be added to the
MPIR documentation.
Just to clarify for Fernando, the code Brian is referring to here is in the
x86_64w directory and is independent of the code that needs to be added to
the x86_64 directory. Native windows uses a different ABI and where
possible MPIR supports it explicitly, rather than automatically.

There is also this file, which is by Jens, and can be used on Haswell,
Broadwell and Skylake. It relies on AVX/BMI2.
You may need to convert line endings. Not sure.
