It may be a bit less confusing to read if I take the inner if out, so
I'll rewrite it like this:
if (input_var || (prog-SeparateShader consumer == NULL)) {
matches.record(output_var, input_var);
}
if (input_var output_var-data.streamId != 0) {
linker_error(prog, ...);
return false;
}
Outputs that are linked to inputs in the next stage must be output to stream 0,
otherwise we should fail to link.

This would appear to prohibit the use of multiple streams in separable
programs entirely. I don't think that's the right thing.

I am a bit confused here:
Reading the code it looks like input_var should be NULL if there is no
consumer stage. In that case, if this is a separable program and there
is no consumer, then input_var must be NULL too, in which case the
linker_error would never take place.
If input_var is not NULL
I had misread it -- yes, this looks correct.
