--- Comment #10 from Richard Biener <rguenth at gcc dot gnu.org> ---
There's more changes/fixes to be backported to fix this on the GCC 10 branc=
h,
like PR97706 and related fixes.  Not sure if it is worth the trouble, the I=
CE
doesn't seem to reproduce for me on the branch but instead I get

t.c: In function 'w7.simdclone.0':
t.c:4:1: error: non-trivial conversion in 'ssa_name'
    4 | w7 (void)
      | ^~
vector(8) unsigned char
vector(8) <unnamed type>
vect__18.21_29 =3D mask__4.19_25;
t.c:4: confused by earlier errors, bailing out

which may be another issue that's latent there.
