IKVM.NET WeblogThe development of a Java VM for .NETUndefined behaviour- February 28, 2003 While fixing bugs in ikvm to get more Mauve tests working (BTW, current results: 224 of 7584 tests failed), I ran across a small but interesting difference between Java and C (and the underlying bytecodes) in converting floating point numbers to integers. Java code: class Test public static void main(String args) float f = Integer.MIN_VALUE; f -= 5; System.out.println((int)(f + 0.5f)); Java output: -2147483648 (=...http://radio.weblogs.com/0109845/2003/02/28.html#a88 Mauve- February 15, 2003 Zoltan has been working on running the Mauve testsuite on IKVM.NET running on Mono and I've been doing the same on MS .NET. Current status on MS .NET: 298 of 7338 tests failedCurrent status on Mono: 143 of 3996 tests failed Thanks to Mark for getting me started with Mauve and thanks to Zoltan for his excellent work on getting ikvm running on Mono.http://radio.weblogs.com/0109845/2003/02/15.html#a87 Getting Eclipse to run- February 12, 2003 In the comments of the previous item John asked for specific instructions to get Eclipse running. Download the most recent IKVM binaries (I just updated them). Download Eclipse. I use build M3. Unzip both zip files. Here I will assume that both are unzipped in the root of C: (the ikvm zip creates an ikvm directory and all the Eclipse files end up in an eclipse directory) Download eclipse.bat, save it in the eclipse directory. Open a Command Prompt window and cd into the eclipse...http://radio.weblogs.com/0109845/2003/02/12.html#a86 Finally back- February 12, 2003 I came across a class file that was the equivalent of the following source: class Test public static final int FOO = 1; static FOO = 1; This isn't legal Java, but the class file equivalent is. The FOO field has a ConstValue attribute with the value 1 and then there is code in the static initializer to set the value again. The code in the static initializer isn't needed and the Java...http://radio.weblogs.com/0109845/2003/02/12.html#a85 |
