How did you create it? x86_32 uses x87 floats which are a lot more
precise than sse ones, for example, so it's best to create a ref file
using such a build.
Does it matter when the result is s16 anyway?
Eh, who knows. Just in case i generated it on x86_32 with -cpuflags 0,
and uploaded it. Confirm it's fine on your end too, otherwise I'll
replace it with your file.
The sample you uploaded seems to work fine for me, on aarch64 with
clang, where the test was failing before.
FWIW, re x86_32 and x87 - some compilers default to SSE2 math even for
x86_32 targets these days, so depending on how you build, you may still
get similar behaviour as to x86_64.
I used gcc 14 and -march=i686 at configure time, so it should not have
sse enabled.
