On about line 1328 inside frexp is this line:

exp = (ex - F.EXPBIAS)>>> 4 - real.mant_dig + 1;

Which produces an error when compiled. Is a blocker for building an ARM cross-compiler.

Regards

Actually, now I've woken up a bit, I *think* what it should be is:

@@ -1345,7 +1345,7 @@
             // denormal
             value *= F.RECIP_EPSILON;
             ex = vu[F.EXPPOS_SHORT] & F.EXPMASK;
-            exp = (ex - F.EXPBIAS)>>> 4 - real.mant_dig + 1;
+            exp = ((ex - F.EXPBIAS)>>> 4) - real.mant_dig + 1;
             vu[F.EXPPOS_SHORT] =
                 cast(ushort)((0x8000 & vu[F.EXPPOS_SHORT]) | 0x3FE0);
         }


Can someone confirm?

Regards
