The nocapture gcc attribute can be on functions only.
The attribute takes one or more unsigned integer constants as parameters
that specify the function argument(s) of const char* type to initify.
If the marked argument is a vararg then the plugin initifies
all vararg arguments.
I couldn't test the arm, arm64 and powerpc architectures.
