Full list of intrinsic functions in HotSpot in JDK 7, 8, 9 and 10
An intrinsic or intrinsic function is a function that the JIT compiler can embed instead of calling Java and JNI code for optimization. An important conclusion from this is that intrinsic functions are not available in interpreter mode. By default, HotSpot uses two C1 and C2 JIT compilers, so the implementation of intrinsic functions may be available for each of the JIT compilers. Differences in the implementation of intrinsic functions for different JIT compilers are caused by different internal code representation ( intermediate representation - IR ).
In HotSpot several hundreds of intrinsics are implemented (their number grows from release to release). A description of all intrinsic functions can be found in the OpenJDK sources in the

In HotSpot several hundreds of intrinsics are implemented (their number grows from release to release). A description of all intrinsic functions can be found in the OpenJDK sources in the
vmSymbols.hpp file. Below are the full lists of intrinsics for JDK 7 ( vmSymbols.hpp ), JDK 8 ( vmSymbols.hpp ), JDK 9 ( vmSymbols.hpp ) and JDK 10 ( vmSymbols.hpp ).The description is as follows:
