Can you give me a pointer to the code for which this was a problem? I'd like<br>
to understand the issue better.<br>
<br>
The VMBIGENDIAN macro was eliminated long ago in favor of a static variable<br>

use dave lewis' runtimediscovery of vm endianness instead of ugly macro<br>
<br>
A macro is faster than dereferencing a variable, but I would be surprised to<br>
find a measurable difference in the overall context of calling a primitive.<br>
<br>
Meanwhile, platform endianness can be determined with #vmEndianness, which<br>
is portable across the oscog and trunk branches. On oscog it uses the macro,<br>
and for the interpreter in trunk it uses the cached value set at runtime.<br>
So I think it should be possible to write the LargeInteger v2 primitives to<br>
work on both branches.<br>
<br>
Thanks,<br>
