$ opt -jump-threading baddress.ll -disable-output
blockaddress may not be used with the entry block!
label %"17"
Broken module found, compilation aborted!


This is a recent regression.  Testcase reduced from linux kernel module
handling code.

define void @module_add_modinfo_attrs() nounwind {
entry:
  br label %"17"

"17":                                             ; preds = %entry
  call void undef(i64 ptrtoint (i8* blockaddress(@module_add_modinfo_attrs,
%"17") to i64), i8* undef, i64 384, i64 undef, i32 32976) nounwind
  unreachable
}
