LGTM with two nits.
================
Comment at: llvm/test/Transforms/InferAlignment/alloca.ll:48
+ %gep.0 = getelementptr %struct.pair, ptr %alloca.struct, i64 0, i32 1
+ %gep.1 = getelementptr { i32, i32 }, ptr %gep.0, i32 1
+
----------------
This one is still going to index out of bounds (as we advance by two pairs total). I would change the index here to `i64 0, i32 1` as well (and the expected alignment would then be `align 4`).
================
Comment at: llvm/test/Transforms/InferAlignment/vscale.ll:13
+ %alloca = alloca <vscale x 4 x i32>, align 1
+ %gep = getelementptr <vscale x 4 x i32>, ptr %alloca, i32 3
+
----------------
These accesses are going to go out of bounds again. Maybe replace the allocas in this test with a `ptr align N` parameter just to make things kosher?
