[Bug java/22299] New: Even length strings (not odd) placed in .section .rodata.jutf8.# at -O1 or above.

[ovidr at users dot sourceforge dot net]

Compiling with -O1 or above.

All even length strings go to ".section  .rodata.jutf8.#", odd length strings 
do not.

class small {
public static void main(String[] a) {
  String S2 = "XX";
  String S3 = "ODD";
  String S4 = "XXXX";
  String S5 = "ODD55";
  String S6 = "XXXXXX";
  String S8 = "XXXXXXXX";
  String S10 = "XXXXXXXXXX";
  String S12 = "XXXXXXXXXXXX";
  String S14 = "XXXXXXXXXXXXXX";
  String S16 = "XXXXXXXXXXXXXXXX";
  String S18 = "XXXXXXXXXXXXXXXXXX";
  String S20 = "XXXXXXXXXXXXXXXXXXXX";
  String S22 = "XXXXXXXXXXXXXXXXXXXXXX";
  String S24 = "XXXXXXXXXXXXXXXXXXXXXXXX";
  String S26 = "XXXXXXXXXXXXXXXXXXXXXXXXXX";
  String S28 = "XXXXXXXXXXXXXXXXXXXXXXXXXXXX";
  String S30 = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
  System.out.println("OK");
}}

Compile:

gcj small.java -S -o small.s -O1

Result:
