Just to clarify, if it isn't already in the spec somewhere else, if a
particular hardware implementation does not support the privilege
extension, it should interpret SVC as a NOP.
Compiler vendors (such as GNU) should use the extension "-march=armv6s-m"
(or equivalent) for optimizing-out SVC if such a level of optimization is
requested (e.g. "-O3").
