@nathanchance Thanks for the report! Here's a minimized test case:
```llvm
; RUN: opt -S -passes=consthoist < %s
target triple = "armv4t-unknown-linux-gnueabi"

define i1 @test(i32 %arg) optsize {
entry:
  %shr.mask = and i32 %arg, -1048576
  %cmp = icmp eq i32 %shr.mask, 380633088
  ret i1 %cmp
}   
```
