Re: 3.9.81: stable BETA

I've done revised asm GEMMs for ARM soft and hard fp, using #defines in the code and -D c -DATL_ARM_HARDFP=1 to enable the hard float ABI, and they work fine. However, there are still places where the -mfloat-abi=softfp in the defaults is not overridden by -Fa alg -mfloat-abi=hard, and this causes the build to fail.

It looks like there are some places in the build process where an option specified with -Fa alg doesn't get appended -- there's an example in support tracker 3531378. If this can be fixed, then the build ought to work, and I can upload a patch for the GEMMs that will enable building on hard fp.

Subject: [atlas-devel] 3.9.81: stable BETA

Guys,

I have just released 3.9.81.  It finishes off the last of my "must-do" for stable, which was support for building dynamic libraries on Windows, OS X, and Linux.  On Windows, this now seems to work for cygwin32/MinGW32/MinGW64.

The only thing I had outstanding besides this is the fact that apparently ubuntu changed the ARM's ABI to default to hard-float.  I haven't gotten feedback from Tom on that, and I don't have access to a machine that uses it, so support for the new ABI will probably be delayed until 3.10.1.

Therefore, as far as I am concerned, I will now start final testing (I have to revalidate all the tests on all the platforms).  Once I get that started running, I will start looking to update all the documentation, and then I plan to release 3.10.0.

So, if you find problems with the 3.9.81, please report them ASAP.

Thanks,
Clint
