EVALUATION I've verified the regression tests fail on a recent build on a local itanium machine. All the failures are for double subnormal inputs. The problem is apparently a code generation issue with the Itanium server compiler. I wrote a simple stand-alone test program with some of the failing values. When the short program was run without a vm option or with -Xint, the proper results are calculated. However, the program fails when run with -Xcomp. import sun.misc.FpUtils; import sun.misc.DoubleConsts; public class test { public static void main(String argv[]) { double [] values = { Double.MIN_VALUE, Double.MIN_VALUE*2, Double.MIN_VALUE*3, FpUtils.nextDown(DoubleConsts.MIN_NORMAL), DoubleConsts.MIN_NORMAL, }; for(int i =0; i < values.length; i++) { System.out.println("0x" + Long.toHexString(Double.doubleToRawLongBits(values[i])) + "\t0x" + Long.toHexString(Double.doubleToLongBits(values[i])) + // "\t" + Double.toHexString(values[i]) + "\t" + FpUtils.ilogb(values[i]) ); } } } (The ilogb failures are mislabled as float when they are actualy double input.) Transferring bug to C2. ###@###.### 2003-07-31
