The following program (compiled to byte or native code): public class IT { public static void main(String[] args) { System.out.println(Integer.MIN_VALUE); System.out.println(0x80000000); System.out.println(Integer.MIN_VALUE == 0x80000000); System.out.println(0x80000000 == 0x80000000); } } Should produce the following output (as it does on i686): -2147483648 -2147483648 true true But on powerpc it produces: -2147483648 -2147483648 false true Release: gcj 3.1
Responsible-Changed-From-To: unassigned->tromey Responsible-Changed-Why: I'm handling this.
State-Changed-From-To: open->analyzed State-Changed-Why: The lexer assumes that HOST_WIDE_INT is 32 bits, leading to problems on PPC Linux, where it is 64 bits. I wrote a first hacky patch, but it needs a rewrite.
