--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. We're having a
(note 32 30 31 (var_location arg2 (const_vector:V2DF [
(const_double:DF 0.0 [0x0.0p+0])
(const_int 0 [0])
])) NOTE_INSN_VAR_LOCATION)
note which obviously will fail a scalar_float_mode assessment. This first
appears in CSE1 as
(insn 8 7 9 2 (set (reg/v:V2DF 92 [ arg2 ])
(const_vector:V2DF [
(const_double:DF 0.0 [0x0.0p+0])
(const_int 0 [0])
])) "t.c":9:22 1167 {*aarch64_simd_movv2df}
(expr_list:REG_DEAD (reg:DF 94)
(nil)))
and is likely a backend pattern issue.

--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The bug is clearly on the aarch64 backend side,
(insn 7 6 8 (set (reg/v:V2DF 73 [ arg2 ])
(vec_concat:V2DF (reg:DF 75)
(const_int 0 [0]))) "pr99808.c":9 -1
(nil))
(insn 8 7 0 (set (reg/v:V2DF 73 [ arg2 ])
(vec_concat:V2DF (vec_select:DF (reg/v:V2DF 73 [ arg2 ])
(parallel:V2DF [
(const_int 0 [0])
]))
(reg:DF 76))) "pr99808.c":9 -1
(nil))
is IMNSHO invalid RTL in both cases. const0_rtx is not valid constant for
DFmode.

This is a dup of PR 99037 then. I was planning on fixing it in GCC 12 but since
there is an ICE reproducer now I can push it in now

aarch64: PR target/99037 Fix RTL represntation in move_lo_quad patterns
This patch fixes the RTL representation of the move_lo_quad patterns to use
aarch64_simd_or_scalar_imm_zero
for the zero part rather than a vec_duplicate of zero or a const_int 0.
The expander that generates them is also adjusted so that we use and match
the correct const_vector forms throughout.

aarch64: PR target/99037 Fix RTL represntation in move_lo_quad patterns
This patch fixes the RTL representation of the move_lo_quad patterns to use
aarch64_simd_or_scalar_imm_zero
for the zero part rather than a vec_duplicate of zero or a const_int 0.
The expander that generates them is also adjusted so that we use and match
the correct const_vector forms throughout.
