See the build configurations below. Also, according to ARM documentation for the CLZ instruction: "This ARM instruction is available in ARMv5T and above. This 32-bit Thumb instruction is available in ARMv6T2 and above. There is no 16-bit Thumb version of this instruction." Can you please provide more info about the config used to replicate the issue?

It may have been he was building distro-less or with his distro, please refer to the "State of bitbake World" email on the oe-core list and maybe reply to Martin for more info. 30094 3 Martin.Jansa 2013-02-26 01:03:23 +0000 No idea since when, but now it seems to be building correctly on distro-less qemuarm.
