Please take a look. In the long term we probably need more general

this type of problem.
I've been thinking about handling it in masm:
When we emit a branch instruction, check if the target label is bound. If
it
is
bound, then we know the distance and can emit the correct branch
instruction.
Otherwise, emit the requested branch instruction + nop, so that later on
we
could change it to a longer jump if the label is bound too far away.
Another approach is to add NEAR/FAR parameter to branch instructions like
in
x64.
We are working on a generic fix. Current preference is not to use Near/Far,
we
are evaluating alternatives (adding nop, using veneer). Probably easier to
discuss offline.
