<pre>In a nutshell, I have a huge piece of code and was looking at the vectorization
analysis from -Rpass-analysis=loop-vectorize which produces a lot of output.
So I went on an ifdefed some large chunk of code out (my program still compiles
fine).
I get a couple of warnings by Rpass analysis that some loop cannot be
vectorized, but to my surprise it points to a line (and shows the line) within
the ifdefed out code.
First thought was, generate the preprocessed sources, delta it, and submit a
bug but... since the code is ifdefed out, the error cannot be reproduced from
the preprocessed sources.
I've been trying to come up with a minimal example that reproduces it for half
an hour without any luck. So this is all I got.</pre>
