Selecting veneer input sections in scatter-loading descriptions

Veneers are used to switch between ARM and Thumb code or to perform a longer program jump than can be specified in a single instruction. You can place veneers at a specific location by including the linker-generated symbol Veneer$$Code in a scatter file. At most, one execution region in the scatter file can have the *(Veneer$$Code) section selector.

If it is safe to do so, the linker places veneer input sections into the region identified by the *(Veneer$$Code) section selector. It might not be possible for a veneer input section to be assigned to the region because of address range problems or execution region size limitations. If the veneer cannot be added to the specified region, it is added to the execution region containing the relocated input section that generated the veneer.

Note

Instances of *(IWV$$Code) in scatter files from earlier versions of ARM tools are automatically translated into *(Veneer$$Code). Use *(Veneer$$Code) in new descriptions.

*(Veneer$$Code) is ignored when the amount of code in an execution region exceeds 4Mb of Thumb code, 16Mb of 32-bit Thumb code, and 32Mb of ARM code.
