One interesting observation:
clang is able to do this:
0.09 │ │ vmovddup -0x8(%rdx,%rsi,1),%xmm3 ▒
...
0.11 │ │ vfmadd231sd %xmm2,%xmm3,%xmm1▒
...

I was also thinking of DCE. It looks like plausible idea. It may leads to a
surprise where you sture same undefined variable to two places and later
compare them for equality, but that is undefined anyway.

Oh, because I missed the -DOPACITY in the second command line. The reason for
SRAs creating the repalcement is total scalarization :-/

Hello, Hubicka and Artem
I try to reproduce this issue in Raptor Lake,
I use -fopenmp -O3 -flto, meet the following error,
but if use -fopenmp -O3, no -flto, build ok.
Could you help me?

This is benchmarkeable version of the simplified testcase:
jan@localhost:/tmp> cat t.c
#define N 1000
struct rgb {unsigned char r,g,b;} rgbs[N];
int *addr;
struct drgb {double r,g,b;
#ifdef OPACITY

Oddly enough simplified version of the loop SLP vectorizes for me:
struct rgb {unsigned char r,g,b;} *rgbs;
int *addr;
double *weights;
struct drgb {double r,g,b;};
struct drgb sum()
{
struct drgb r;
