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

We use the Linaro x86 toolchain to cross-compile full system images
for our embedded target, which work great. I apply a subset of the
Ubuntu patchset to Linaro gcc and gdb as well as upstream eglibc and
binutils. (I omit the multilib patches and some other things that
didn't seem necessary for t
I should be able to equip you soon with a web browsing benchmark based
on Firefox's Talos suite (https://wiki.mozilla.org/Buildbot/Talos).
The most representative test (tp5) unfortunately depends on a data set
that we can't distribute; but there are SunSpider and Dromaeo suites
as well, and I am su
Please coordinate with Jon Masters at RedHat/Fedora and Adam Conrad at
Ubuntu/Debian on this. (Cc'ing the cross-distro list, through which the
recent ARM summit at Linux Plumbers was organized.)

The calling convention for makecontext() isn't just an issue for standards
lawyers, it's an actual problem on ARM, especially on hard-float systems.
According to the standard, "The application shall ensure that the value of
argc matches the number of arguments of type int passed to func; otherwise,
