Hi,
I ran some testing on the soon-to-be-committed matmul patch.
Specifically, I tried out what putting -march=native into
libgfortran's Makefile.
Here is the performance data with the new code without -march.
The interesting numbers are the ones for Matml fixed explicit,
for size>=32.

I should have added that this was for a system with AVX
(namely an i7-2600).

Hi Guys,
Long time, no post. Sorry about that. So, in order to make up for
it, here is an extra long update on the state of the GNU toolchain:
In GCC land, 6.2 has now been released and GCC 7 is almost ready to
branch. Here are the new features that you can expect to find in
GCC 7:
Hi,
new Intel instructions AVX512_4FMAPS and AVX512_4VNNIW introduce use
of register groups.
To support register groups feature in inline asm needed some extension
with new constraints.
Current proposal is the following syntax:
__asm__ (“SMTH %[group], %[single]" :
Snapshot gcc-5-20161115 is now available on
ftp://gcc.gnu.org/pub/gcc/snapshots/5-20161115/
and on various mirrors, see http://gcc.gnu.org/mirrors.html for details.
This snapshot has been generated from the GCC 5 SVN branch
with the following options: svn://gcc.gnu.org/svn/gcc/branches/gcc-5
Many of the GCC features listed here are not mentioned in
gcc-7/changes.html. We all need to expand that to be more thorough in
covering features that are new in GCC 7 compared to GCC 6.
