__sev intrinsic

This intrinsic inserts a SEV instruction into the instruction stream generated by the compiler.

In some architectures, for example the v6T2 architecture, the SEV instruction executes as a NOP instruction.


void __sev(void)


The compiler does not recognize the __sev intrinsic when compiling for a target that does not support the SEV instruction. The compiler generates either a warning or an error in this case.
