X32 abi

Vision

Incorporate toolchain components and other bits (binutils, gcc, glibc, gdb, kernel, linux-libc-headers) into a meta-x32 layer; And added needed infrastructure into the oe-core/yocto tree so that meta-x32 layer can work on top; so that one can build complete images with x32 abi binaries.

Tasks

• Create x32-layer & populate x32 specific recipes in it - done
  • create gcc-4.7, glibc2-14, kernel-2.6.38.y & other working recipes
• Get core-image-minimal image building and running - done
  • Fix the recipes which break with x32- Fixed glib-2.0, openssl, udev, busybox
• Integrate infrastructure pieces of x32 integrated in oe-core/yocto
  • qemux32 change
  • siteinfo changes
    • create a new tripplet for x32,
    • support multiple ABIs per architecture
  • multilib changes will be needed soon
• assess how much work somehting like X11 and maybe sato would be
• List all the recipes which fail with x32 toolchain
  • x32-broken-recipes-list
• try and find some way of assessing performance
