[meta-openembedded/toolchain-layer] Adding retired toolchain support for gcc-4.5.1 and eglibc-2.13

[Elvis Dowson]

Hi,
      I've created a set of patches to add retired toolchain support for gcc-4.5.1, to the meta-openembedded/toolchain-layer. 

I've also included a patch for eglibc-2.13. Builds for PowerPC 440 processors soft-float don't work with eglibc-2.15 and 2.16.

I could add it to the meta-xilinx layer, but I prefer to put retired toolchain support into the toolchain layer, so that it is generally available across all layers, in case someone needs it.

Do let me know if it is okay to go ahead and submit these patches for inclusion into the meta-openembedded/toolchain-layer!

Best regards,

Elvis Dowson

Were you able to build eglibc 2.13 with gcc 4.7
And run it

The gcc-4.7 and eglibc-2.13 combination doesn't work, i.e. no
login or bash prompt.

I will try with gcc-4.6 and eglibc-2.13, since that combo is
know to work, since the Denx ELDK 5.2.1 released based
off yocto/denzil branch uses it.

Will let you know how it goes.

Given that  4.5.x was deleted from meta-toolchain 3 months ago[1], what's
the rationale for adding it back? It's still available in the denzil branch,
so unless someone steps up to maintain it I'm inclined to say "no" to
patches bringing it back in the master branch.

Koen

The gcc-4.5 recipe was adapted from the gcc-4.5.1 recipe from the denzil branch.

The structure of the newer gcc-4.7 recipes in the current poky/master branch are
a bit different from the older recipes in the denzil branch. So, while developing
the gcc-4.5 recipes, I started with the existing gcc-4.7 templates, and looked at the
gcc-4.6 recipes in the current meta-openembedded/toolchain-layer and 
incorporated all the patches for gcc-4.5.1 from the denzil branch. This way the
gcc-4.5 recipe would be compatible with builds against the current poky/master
branch, and take advantage of all the newer recipe versions, in the current
poky/master branch, while maintaining legacy support for the gcc-4.5.1 toolchain.

The problem I ran into was with support for soft-float on the PowerPC440 processor.

If I can isolate the issue, and get it to work with gcc-4.6 or gcc-4.7, there is no need
to add legacy gcc-4.5 toolchain support to the toolchain-layer.

If not, then it would be required to maintain support, atleast for PowerPC 440 targets
with soft-float.

The meta-toolchain denzil branch had 4.5.4

What is 'poky'?

Again, the meta-toolchain denzil branch had 4.5.4

Yes, you're right. I intentionally dropped it to 4.5.1, but I'll update the existing
recipes 4.5.4.
