- * <p>Below is an example of the code generated for the {@link
- * HeapMemorySegment#putLongBigEndian(int, long)} function by the just-in-time compiler. The code is
- * grabbed from an Oracle JVM 7 using the hotspot disassembler library (hsdis32.dll) and the jvm
- * command <i>-XX:+UnlockDiagnosticVMOptions
- * -XX:CompileCommand=print,*MemorySegment.putLongBigEndian</i>. Note that this code realizes both
- * the byte order swapping and the reinterpret cast access to get a long from the byte array.
