Veneers allow switching between ARM and Thumb code or allow
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
Veneer$$Code in a scatter file. At most,
one execution region in the scatter file can have the
If it is safe to do so, the linker places veneer input sections
into the region identified by the
selector. It might not be possible for a veneer input section to
be assigned to the region because of address range problems or execution
region size limitations. If the veneer cannot be added to the specified
region, it is added to the execution region containing the relocated
input section that generated the veneer.
*(IWV$$Code) in scatter files
from earlier versions of ARM tools are automatically translated
*(Veneer$$Code) is ignored when the amount
of code in an execution region exceeds 4Mb of 16-bit encoded Thumb
code, 16Mb of 32-bit encoded Thumb code, and 32Mb of ARM code.
