oh wait - i recognise that: that's debug output from stdout.  you're
running "python3 examples/part_sig_add.py > part_sig_add.il" aren't you?

it should be just "python3 examples/part_sig_add.py".

if you have a look at the source you'll see it creates part_sig_add.il
as part of the "create_ilang()" function.

btw so that you get some "sync" statements, i've added a new class
TestAddMod2 and you'll need to do a "git pull" on both soclayout
as well as ieee754fpu.  then:

soclayout$ make -f Makefile2 lvx
