This looks like an ira/reload bug. The ira dump is where the offending insns
first show up.
(insn 17 26 244 3 pr42431.f:27 (set (mem:V4SI (reg/f:DI 29 29 [255]) [4 S16
A128])
(reg:V4SI 108 31 [269])) 942 {*altivec_movv4si} (expr_list:REG_EQUAL
(const_vector:V4SI [
(const_int 0 [0x0])
(const_int 0 [0x0])
(const_int 0 [0x0])
(const_int 0 [0x0])
])
(nil)))
(insn 244 17 245 3 pr42431.f:27 (set (reg:DI 9 9)
(mem/u/c:DI (plus:DI (reg:DI 2 2)
(const:DI (unspec:DI [
(symbol_ref/u:DI ("*.LC2") [flags 0x2])
] 49))) [7 S8 A8])) 373 {*movdi_internal64} (nil))
(insn 245 244 20 3 pr42431.f:27 (set (reg:DI 9 9)
(plus:DI (reg:DI 9 9)
(reg:DI 9 9))) 83 {*adddi3_internal1} (nil))
(insn 20 245 246 3 pr42431.f:27 (set (mem:V4SI (reg:DI 9 9) [4 S16 A128])
(reg:V4SI 108 31 [269])) 942 {*altivec_movv4si} (expr_list:REG_EQUAL
(const_vector:V4SI [
(const_int 0 [0x0])
(const_int 0 [0x0])
(const_int 0 [0x0])
(const_int 0 [0x0])
])
(nil)))
insns 244/245 are not present in the prior (sched1) dump. insn 245 should be
adding the constant 16 to gpr9 instead of adding r9.
