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.

meta-x32 changes were integrated into OE-Core.

X32 poky setup

  • Add these lines to local.conf
MACHINE = "qemux86-64"
DEFAULTTUNE = "x86-64-x32"
