Sebastian Pop b226b5d5c0 [SCEVExpand] do not hoist divisions by zero (PR30935) ... SCEVExpand computes the insertion point for the components of a SCEV to be code generated. When it comes to generating code for a division, SCEVexpand would not be able to check (at compilation time) all the conditions necessary to avoid a division by zero. The patch disables hoisting of expressions containing divisions by anything other than non-zero constants in order to avoid hoisting these expressions past conditions that should hold before doing the division. The patch passes check-all on x86_64-linux.
