Here's an implementation of an 8x8 integer DCT done with NEON
intrinsics -- essentially a translation of the assembly version in
libjpeg-turbo trunk:

I've added a pico-SAM9G45 board to my home office setup. It's called
libra1 and runs Debian 6.0. The nice thing about this board is it has
256 MB of RAM and should be able to run SPEC 2000.
I'll start using it to check that our GCC changes don't cause
significant performance regressions on earli
Hi,
by any chance, are you trying to build gcc with c++ support before
building a libc?
The usual cause for this is that you don't have a libc yet. (You have
to build a minimal compiler (just C) first, then use that to build a
libc, then build a full compiler).

Continued work on widening multiplies. Finally got a point where I have
something I'm happy to post upstream! Posted here:

Richard Guenther reviewed one of the patches, and found a flaw, so I've
been working on addresssing that.
Hello,
It succeeded! Thanks~

Hi,
you may have to regenerate the configure scripts -- the patch touches
a file that is only used during configure script generation.
Try running
aclocal -I config
autoconf
in libstdc++-v3 after applying the patch.
