+Summary: xsp fails on solaris
+
+As reported on m-d-l, xsp does not work on solaris under the JIT.
+The problem is caused by the JIT miscompiling the following code:
+
+using System;
+
+public class Tests {
+
+public static void Main ()
+{
+	checked {
+		long val = 10000;
+		new TimeSpan (val * 10000);
+	}
+}
+}
+
+The problem here is the val * 10000 assignment is compiled to a call,
+and that call overwrites the the %0 register which contains the address
+of the valuetype which needs to be passed to the constructor:
+
+ (outarg (ldaddr regoffset[-0x10(sparc_fp)]))
+ (sparc_outarg_regpair (ldind.i8 regoffset[-0x8(sparc_fp)]))
+ (sparc_outarg_regpair (conv.u8 iconst[10000]))
+ (stind.i8 regoffset[-0x18(sparc_fp)] lcall)
+ (sparc_outarg_regpair (ldind.i8 regoffset[-0x18(sparc_fp)]))
+ voidcall[.ctor]
