mir file that can't be read by llc

error: buggy.mir:50:39: unexpected character '/'
successors: %bb.1.true(0x40000000 / 0x80000000 = 50.00%),

LLVM ERROR: Unable to initialize machine function
The input mir file was obtained by running llc -mtriple=aarch64-unknown
-stop-after=block-placement <some .ll file> -o buggy.mir.
If we remove the block frequencies from the file, it manages to read it, but
the output that it produces also contains block frequencies, so it can't be
read back in.</pre>
