lld assumes some ARM features that are not available in all Arm processors. In particular: - The blx instruction present for interworking. - The movt/movw instructions are used in Thunks. - The J1=1 J2=1 encoding of branch immediates to improve Thumb wide branch range are assumed to be present. This patch reads the ARM Attributes section to check for the architecture the object file was compiled with. If none of the objects have an architecture that supports either of these features a warning will be given. This is most likely to affect armv6 as used in the first Raspberry Pi.
