--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
vector lowering produces
_5 = BIT_FIELD_REF <f_1(D), 64, 0>;
_6 = (_Decimal32) _5;
_7 = BIT_FIELD_REF <f_1(D), 64, 64>;
_8 = (_Decimal32) _7;
_9 = BIT_FIELD_REF <f_1(D), 64, 128>;
_10 = (_Decimal32) _9;
_11 = BIT_FIELD_REF <f_1(D), 64, 192>;
_12 = (_Decimal32) _11;
d_2 = {_6, _8, _10, _12};
where the BIT_FIELD_REFs extract _Float64. Then forwprop matches the
CTOR as VEC_PACK_TRUNC_EXPR from vector(2) _Float64 to vetor(4) _Decimal32.
_13 = BIT_FIELD_REF <f_1(D), 128, 0>;
_14 = BIT_FIELD_REF <f_1(D), 128, 128>;
d_2 = VEC_PACK_TRUNC_EXPR <_13, _14>;
I'm not sure if decimal FP vectors are a thing on powerpc64le and what their
ABI are. Maybe the testcase should be rejected.
Clearly the forwprop code is wrong here, since the vec_pack_trunc optab
has just a single mode there's no way to convert between DFP and FP.
I'll fix that, not sure if that will fix everything.

tree-optimization/104511 - avoid FP to DFP conversion for VEC_PACK_TRUNC
This avoids forwprop from matching DFP <-> FP vector conversions
using VEC_[UN]PACK{_TRUNC,_LO,_HI}. Maybe DFP vectors shouldn't be
a thing, but they appearantly are. Re-using CONVERT/NOP_EXPR for
DFP <-> FP conversions was probably a mistake.
