<pre>When compiling the following IR with `llc -filetype=obj -relocation-model=pic`:
target triple = "i686-pc-windows-msvc"
define void @foo(i8) {
entry-block:
switch i8 %0, label %bb2 [
i8 1, label %bb1
i8 2, label %bb2
i8 3, label %bb3
i8 4, label %bb4
i8 5, label %bb5
]
bb1:
ret void
bb2:
ret void
bb3:
ret void
bb4:
ret void
bb5:
ret void
}
The error "LLVM ERROR: No open frame" is printed. A bisection pointed at
r254874 as the faulty commit, which looks like it was tweaking the calls around
that site as well?</pre>
