I think series_p clearly documents that:
/* Return true if index OUT_BASE + I * OUT_STEP selects input
element IN_BASE + I * IN_STEP. For example, the call to test
whether a permute reverses a

Jakub, you are too fast! Anyway, nice test-case. So far I was able to come to
something semi-reduced:
typedef struct {
float r;
float i;
} kiss_fft_cpx;

Neither of those vec_perms are valid targets for this optimization.
It looks like sel.series_p is not doing what I expected. It's matching even
elements and ignoring the odd ones.

So are we talking about
typedef float V __attribute__((vector_size (16)));
typedef int VI __attribute__((vector_size (16)));
V
foo (V x, V y)
{
V a = x - y;
V b = y + x;
return __builtin_shuffle (b,

Hmm I was seeing the change in opus_ifft but that does look like different
codegen :/ I might not be looking at the right thing.
That transformation looks definitely wrong though as the

I've just isolated that to celt/kiss_fft.c, can you confirm the change comes
from the file?

Thanks!
My initial investigation has lead me to think the change is being caused at
vrp2, which is the only time the pattern gets triggered with -O2, the tree

Steps to reproduce:
$ wget https://archive.mozilla.org/pub/opus/opus-1.3.1.tar.gz
$ tar xvzf opus-1.3.1.tar.gz
$ cd opus-1.3.1/
$ ./configure
$ make -j32 && make -j32 check
So it fails even with default

That patch only fixed the bootstrap, in any case I'm on holidays so have asked
someone else to look.
