Hello all,
Currently to support 32b and 64b build for same core in Yocto, two separated compilers need to be generated. Is there plan to support multilib build(32b and 64b) by single toolchain which is generated by Yocto in future?
Best Regards,
Zhenhua

The requirements for multilib compilers depend on architecture, configuration
and GNU GCC limitations. Some architects will work fine with a single compiler,
others may require multiple compilers.
If you can assist with this effort, I believe the work would be appreciated.

[Luo Zhenhua-B19537] It is feasible to generate the single toolchain with multilib support in Yocto, is the understanding right?
Do you mind to give more details of above comments for better understanding?
Best Regards,
Zhenhua
