Re: endianness of lua bytecode?

[Ando Sonenblick <ando@...>]

Fabio,

thx for the insight.  So, if the endianness of the byte code dump is 
stored within the dump does that mean that I can take the bytecode that 
was "compiled" from text on a little endian machine, save it to disk, 
then load it on a machine that is big endian and run the dump and lua 
will properly notice the endianness mismatch and byte swap as 
necessary?

Or can you simply not take byte code from one endian machine onto an 
opposite endian machine?

thx,
ando
