Enable cloog/ppl when compiling gcc

This patchset contains

Changes to gcc where now it will be compiled with cloog/ppl support and we have corresponding libraries build as -native and -nativesdk recipes

Fixes the beagleboard ICE seen with mesa-xlib sometime ago and removes the workaround for the same

Updates eglibc 2.14 to tip of SVN branch

Fixes gnutls build failure observed on uclibc

The following changes since commit 0a7a8597be05c8def8af58eecab49d963dc9d757:

libsdl: Disable pulseaudio explicitly (2011-12-05 23:03:23 +0000)

These are supporting libraries needed if we want to build gcc with graphite support which does better job on loop optimizarions.

That is missing a PR bump :)

regards,

Koen

native.bbclass already sets STAGING_DIR_HOST correctly to be empty. It looks wrong but its correct when you think about it since the installed binaries are at their final location where we intent to execute them (in ${prefix}).

Cheers,

Richard

OK in this case then I think we are better of using --with-gmp-prefix=${STAGING_EXECPREFIXDIR} here which should work for target/native/nativesdk
variants

is this when you build gcc for target ?

Thanks for trying it out.

Yes I should. I had it for a while but then I removed it for experimenting if it will find libs in sysroot and it did and since then I removed it but I forgot that I do not have gmp libs installed locally on build system.

I will fix it here and push a new patch to same branch

while building ppl for target, ppl-native was built fine

http://patches.openembedded.org/patch/16301/

This gives a hit to the build time of the toolchain and I'm not sure what benefits its buying us, particularly if we don't enable the optimisations that cloog/ppl is used for.

Whilst this looks nice for experimentation, are there documented benefits for a system compiled with this?

Cheers,

Richard

The total compile time of the toolchain is impacted little since now we have to build these extra packages but they are relatively small. However I think I need to measure the total compile time as well to make sure it does not impact gcc's compile
time performance. My intention was to
provide the capability in the compiler/SDK so that someone can utilize it if he/she wants. e.g. gnuradio folks I am sure will benefit from it

I did not find official documented advantages but there has been several posts where improvement in performance has been observed. There was a lengthy thread I found on gentoo where they saw total system performance boost when they enabled
graphite.

I think it is more of RFC so people can try it out and then we can weigh in benefits of it in OE context.

I merged these.

but I think these need more discussion.

Cheers,

Richard
