David Majnemer 0ab2058852 IR: Do not canonicalize constant GEPs into an out-of-bounds array access ... Summary: Consider a GEP of: i8* getelementptr ({ [2 x i8], i32, i8, [3 x i8] }* @main.c, i32 0, i32 0, i64 0) If we proceeded to GEP the aforementioned object by 8, would form a GEP of: i8* getelementptr ({ [2 x i8], i32, i8, [3 x i8] }* @main.c, i32 0, i32 0, i64 8) Note that we would go through the first array member, causing an out-of-bounds accesses. This is problematic because we might get fooled if we are trying to evaluate loads using this GEP, for example, based off of an object with a constant initializer where the array is zero. This fixes PR17732.
