Thanks to @eme64 's patience and help, I found a way to use MergeStore without doing boundary checking. It would be even better if Unsafe.putChar could be used for MergeStore in the future. ## 1. JavaCode class StringUTF16 { public static void putCharsAt(byte[] value, int i, char c1, char c2, char c3, char c4) { // Don't use the putChar method, Its instrinsic will cause C2 unable to combining values into larger stores. putChar1(value, i , c1); putChar1(value, i + 1, c2); putChar1(value, i + 2, c3); putChar1(value, i + 3, c4); } public static void putCharsAt(byte[] value, int i, char c1, char c2, char c3, char c4, char c5) { // Don't use the putChar method, Its instrinsic will cause C2 unable to combining values into larger stores. putChar1(value, i , c1); putChar1(value, i + 1, c2); putChar1(value, i + 2, c3); putChar1(value, i + 3, c4); putChar1(value, i + 4, c5); } static void putChar1(byte[] value, int i, char c) { int address = Unsafe.ARRAY_BYTE_BASE_OFFSET + (i << 1); Unsafe.getUnsafe().putByte(value, address , (byte)(c >> HI_BYTE_SHIFT)); Unsafe.getUnsafe().putByte(value, address + 1, (byte)(c >> LO_BYTE_SHIFT)); } } ## 2.
