[Buildroot] [PATCH v3 0/6] OpenCV update and CPU fetures

[Samuel Martin]

This patch series add some symbols for some of these features for
x86/x86_64 and PowerPC architures.

These new symbols are used in this 2nd version of the OpenCV patch, as
well as in some other packages.

Changes since v2:
- rename x86/x86_64 cpu feature symbols: BR2_CPU_HAS_* -> BR2_X86_CPU_HAS_*
- add CPU features symbols for PowerPC
- opencv: bump to version 2.4.1
- fix/cleanup menuconfig
- update opencv configure options

Changes since v1:
- add CPU features symbols for x86 and x86_64
- use those symbols in the opencv, sdl_gfx and sdl_sound packages
- opencv: add missing zlib dependency

Samuel Martin (6):
  target: add symbols for i386/x86_64 cpu features
  target: add symbols for PowerPC cpu features
  libevas: refactor *_CONF_OPT assignment with cpu-feature options
  sdl_gfx: refactor *_CONF_OPT assignment with cpu-feature options
  sdl_sound: refactor *_CONF_OPT assignment with cpu-feature options
  opencv: bump to version 2.4.1

-[PATCH] Fix compile issue in flann module on uClibc without long double support
-
-uClibc configured without UCLIBC_HAS_LONG_DOUBLE_MATH (because of user
-choice or simply that the arch doesn't provide long doubles) doesn't
-provide fabsl(), breaking the build in the flann module.
-
-Work around it by not providing the long double template specialization.

Note that I'm not sure about this configure options...
Indeed, looking at the sources, setting ENABLE_POWERPC=ON adds
'-mcpu=G3 -mtune=G5' to the cflags...

I'm not sure how these may conflict with those set by Buildroot.
Any inputs about this are welcome.

What problem is this solving exactly? I don't recall seeing any failures
on the autobuilders, and host-pkg-config + libglib2 are already
dependencies of gstreamer, so it shouldn't be needed to list them
explicitly.

From a quick look at the (handwritten) configure script, is seem to get
cflags / libs from pkg-config as well.

  Maybe it makes sense to have a config BR2_x86_geode_mmx ?

  I was expecting Altivec here, not the PowerPC CPU generations...  These CPU
features are relevant mostly to allow libraries to select optimized assembly
code, and I don't see much use of G5-specific assembly.  And anyway, the
-mcpu options for a particular CPU are already passed by buildroot.

Also the G5 is 64-bit capable so one might expect some issues down the 
line since we're not ppc64-capable at the moment.

hum... the problem was not found headers (the 3 mentioned above), but
actually this seems to be caused by a dirty work tree/build and
staging directories...
A git clean -fdx and a build from scratch fix it.

So, forget about this patch.

Apologize for the noise.

Actually, I made this choice after talking about it with Peter and
ThomasP on IRC (that's Peter who gave me the link).

BTW, packages that may take benefit from MMX features (like libevas or
sdl_{gfx,sounds}) did not turn it on before, neither after this patch
series.

IMHO, I prefer keeping things in a safe shape like this.

I would expect nothing less ;-)

So, to sum up and make the relation with the question I asked on the
pacth 6/6 of the serie, you suggest I always turn off the
ENABLE_POWERPC option in the opencv package. That's it?

BTW, I can add an Altivec symbol, and let you (or others) use it in
packages that may take benefit from such optimization.
Let me know...
