Interestingly enough, if I do this instead:

in way that could be auto-vectorized, saving me to write assembler or using
specific vectorization extensions. Unfortunately I've not yet managed to make
gcc vectorize any of them.
I've simplified the case to ju

The following draft patch disables the debuginfo disabling when using
-flto or -fwhopr and fixes up things so that for C debugging (mostly)

The main question I have is how to proceed further here (with the
goal that simple debugging should be possible in 4.5). If we
