Did you use some generator which you can provide so other people could
generate the same testdate if needed?

Can you generate a smaller test selecting random instructions from this
big test file (several 10k) so we can add it to the testsuite? See
http://svn.freepascal.org/svn/fpc/trunk/tests/test/tasm2.pp how correct
assembling can be automatically tests (the byte array is a dump of the
file assembled by gas/nasm?)
