I'm searching where os.arch is reported on OpenJDK 7 and 8 to
complement my patches for universal (32/64bits)
in jdk/src/macosx/native/jobjc/src/core/java/com/apple/jobjc/JObjCRuntime.java,
I could see :
public final class JObjCRuntime {
static { System.loadLibrary("JObjC"); }
public static enum Arch{ ppc, i386, x86_64 };
public static enum Width{ W32, W64 };
public static final Arch ARCH = getArch();
public static final Width WIDTH = getWidth();
private static Arch getArch(){
String arch = System.getProperty("os.arch");
if("ppc".equals(arch)) return Arch.ppc;
if("i386".equals(arch)) return Arch.i386;
if("x86_64".equals(arch)) return Arch.x86_64;
if("amd64".equals(arch)) return Arch.x86_64;
if("universal".equals(arch)) return Arch.x86_64;
throw new RuntimeException("Did not recognize os.arch system
property: '" + arch + "'");
}
Should it be :
private static Arch getArch(){
String arch = System.getProperty("os.arch");
if("ppc".equals(arch)) return Arch.ppc;
if("i386".equals(arch)) return Arch.i386;
if("x86_64".equals(arch)) return Arch.x86_64;
if("amd64".equals(arch)) return Arch.x86_64;
if("universal".equals(arch) && getWidth() == Width.W64) return
Arch.x86_64;
if("universal".equals(arch) && getWidth() == Width.W32) return
Arch.i386;
throw new RuntimeException("Did not recognize os.arch system
property: '" + arch + "'");
}
