This intrinsic inserts a
SEV instruction into the instruction stream generated by the compiler.
In some architectures, for example the v6T2 architecture, the
instruction executes as a
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, depending on the source language:
- In C code:
Warning: #223-D: function "__sev" declared implicitly.
- In C++ code:
Error: #20: identifier "__sev" is undefined.
