This changed with r249896.
Creating dr for *pin_64
analyze_innermost: success.
- base_address: &in
+ base_address: pin_64
offset from base address: 0
constant offset from base address: 0
- step: 32
+ step: 0
aligned to: 128
base_object: *pin_64
Creating dr for *pout_65
analyze_innermost: success.
- base_address: &out
+ base_address: pout_65
offset from base address: 0
constant offset from base address: 0
- step: 32
+ step: 0
aligned to: 128
base_object: *pout_65
and similarly many times,
-bb-slp-1.c:25:7: note: misalign = 0 bytes of ref *pin_64
+bb-slp-1.c:25:7: note: can't force alignment of ref: *pin_64
+bb-slp-1.c:25:7: note: Vectorizing an unaligned access.
... and finally
-bb-slp-1.c:15:3: note: basic block vectorized
