+Summary: Interpreter fails on PPC
+
+Description of Problem:
+
+I have experimented with Mono a few times before, once in 2002/01 on an ARM
+ CPU, I had sent the results to a core Mono hacker. Last year I tried Mono
+on a PowerPC, more specifically, a Motorolla MPC823E running at 75MHz which
+has no FPU.
+(mono-20030408-2315)
+
+Today, I tried the latest CVS version and noticed that it does run with the
+interpreter (mint). But simple examples using the FPU fail, the following
+test application outputs 0 when floats or doubles are used.
+
+Notice that the old mint binary still outputs *correct* results, equal to
+the results on my x86.
+
+The new JIT (mini -> mono) fails immediatly with the following message:
+"Trace/breakpoint trap"
+
+Steps to reproduce the problem:
+1. Compile the Test.cs file.
+2. Execute on a PPC without FPU
+
+
+Test.cs:
+using System;
+class Test
+{
+ public static void Main()
+ {
+ float f = 12345.6789f;
+ Console.WriteLine(f);
+ double dob = 12345.6789d;
+ Console.WriteLine(dob);
+ decimal d = 123456789.123456789m;
+ Console.WriteLine(d);
+ }
+}
+
+
+Actual Results:
+0
+0
+123456789.123456789
+
+
+Expected Results:
+12345.68
+12345.6789
+123456789.123456789
+
+How often does this happen?
+Always.
+
+Additional Information:
+
+
+
+Part of trace when running the JIT:
