Before reload, we have this sequence:
--cut here--
(insn 34 4 2 2 (set (reg:TI 119)
(reg:TI 20 xmm0 [ u ])) "pr110372.c":8:1 89 {*movti_internal}
(expr_list:REG_DEAD (reg:TI 20 xmm0 [ u ])
(nil)))
(insn 2 34 3 2 (set (reg/v:TI 98 [ u ])
(reg:TI 119)) "pr110372.c":8:1 89 {*movti_internal}
(expr_list:REG_DEAD (reg:TI 119)
(nil)))
(note 3 2 7 2 NOTE_INSN_FUNCTION_BEG)
(insn 7 3 9 2 (set (reg:V4SI 83 [ _2 ])
(and:V4SI (subreg:V4SI (reg/v:TI 98 [ u ]) 0)
(mem/u/c:V4SI (symbol_ref/u:DI ("*.LC0") [flags 0x2]) [0 S16
A128]))) "pr110372.c":9:14 6840 {*andv4si3}
(expr_list:REG_EQUAL (and:V4SI (subreg:V4SI (reg/v:TI 98 [ u ]) 0)
(const_vector:V4SI [
(const_int 4 [0x4]) repeated x4
]))
(nil)))
--cut here--
And reload tries to move xmm0 to xmm1 with:
(insn 36 3 41 2 (set (reg:DI 0 ax [123])
(reg:DI 20 xmm0 [orig:98 u ] [98])) "pr110372.c":9:14 90
{*movdi_internal}
(nil))
(insn 41 36 37 2 (set (mem/c:TI (plus:DI (reg/f:DI 7 sp)
(const_int -40 [0xffffffffffffffd8])) [2 %sfp+-32 S16 A128])
(reg/v:TI 20 xmm0 [orig:98 u ] [98])) "pr110372.c":9:14 89
{*movti_internal}
(nil))
(insn 37 41 43 2 (set (reg:DI 24 xmm4 [124])
(mem/c:DI (plus:DI (reg/f:DI 7 sp)
(const_int -32 [0xffffffffffffffe0])) [2 %sfp+-24 S8 A64]))
"pr110372.c":9:14 90 {*movdi_internal}
(nil))
(insn 43 37 38 2 (set (reg:DI 23 xmm3 [122])
(reg:DI 0 ax [123])) "pr110372.c":9:14 90 {*movdi_internal}
(nil))
(insn 38 43 39 2 (set (reg:V2DI 23 xmm3 [122])
(vec_concat:V2DI (reg:DI 23 xmm3 [122])
(reg:DI 24 xmm4 [124]))) "pr110372.c":9:14 7265 {vec_concatv2di}
(nil))
(insn 39 38 7 2 (set (reg:V4SI 21 xmm1 [orig:83 _2 ] [83])
(reg:V4SI 23 xmm3 [122])) "pr110372.c":9:14 1869 {movv4si_internal}
(nil))
in order to satisfy constraints of:
(insn 7 39 9 2 (set (reg:V4SI 21 xmm1 [orig:83 _2 ] [83])
(and:V4SI (reg:V4SI 21 xmm1 [orig:83 _2 ] [83])
(mem/u/c:V4SI (symbol_ref/u:DI ("*.LC0") [flags 0x2]) [0 S16
A128]))) "pr110372.c":9:14 6840 {*andv4si3}
(expr_list:REG_EQUAL (and:V4SI (subreg:V4SI (reg/v:TI 20 xmm0 [orig:98 u ]
[98]) 0)
(const_vector:V4SI [
(const_int 4 [0x4]) repeated x4
]))
(nil)))
Please note that alternative 19 of *movdi_internal from i386.md (?r,?v) is
correctly enabled only for x64_sse2 ISA, so unavailable without SSE2.
We have:
#define VALID_SSE_REG_MODE(MODE) \
((MODE) == V1TImode || (MODE) == TImode \
|| (MODE) == V4SFmode || (MODE) == V4SImode \
|| (MODE) == SFmode || (MODE) == SImode \
|| (MODE) == TFmode || (MODE) == TDmode)
So, TImode and V4SImode should be tieable for XMM registers and RA should just
copy the value between XMM registers.

LRA: Refine reload pseudo class
For given testcase a reload pseudo happened to occur only in reload
insns created on one constraint sub-pass. Therefore its initial class
(ALL_REGS) was not refined and the reload insns were not processed on
the next constraint sub-passes. This resulted into the wrong insn.
PR rtl-optimization/110372
gcc/ChangeLog:
* lra-assigns.cc (assign_by_spills): Add reload insns involving
reload pseudos with non-refined class to be processed on the next
sub-pass.
* lra-constraints.cc (enough_allocatable_hard_regs_p): New func.
(in_class_p): Use it.
(print_curr_insn_alt): New func.
(process_alt_operands): Use it. Improve debug info.
(curr_insn_transform): Use print_curr_insn_alt. Refine reload
pseudo class if it is not refined yet.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr110372.c: New.
