--- Comment #3 from Segher Boessenkool <segher at gcc dot gnu.org> ---
This is caused by r275959, the commit that added this assert.

Trying 14 -> 15:
14: r96:V1DI#0=flags:CCZ!=0
REG_DEAD flags:CCZ
15: {r99:DI=r100:DI|r96:V1DI#0;clobber flags:CC;}
REG_DEAD r100:DI
REG_UNUSED flags:CC
REG_DEAD r96:V1DI
Failed to match this instruction:
(parallel [
(set (reg:DI 99 [ vect_sq_12.9 ])
(ior:DI (ne:DI (reg:CCZ 17 flags)
(const_int 0 [0]))
(reg:DI 100)))
(clobber (reg:CC 17 flags))
])
Failed to match this instruction:
(set (reg:DI 99 [ vect_sq_12.9 ])
(ior:DI (ne:DI (reg:CCZ 17 flags)
(const_int 0 [0]))
(reg:DI 100)))
and that is all perfectly okay (the subregs here are mode DI, one of the
crucial things slim doesn't print).
