-/// getLSDAEncoding - Returns the LSDA pointer encoding. The choices are 4-byte,
-/// 8-byte, and target default. The CIE is hard-coded to indicate that the LSDA
-/// pointer in the FDE section is an "sdata4", and should be encoded as a 4-byte
-/// pointer by default. However, some systems may require a different size due
-/// to bugs or other conditions. We will default to a 4-byte encoding unless the
-/// system tells us otherwise.
-///
-/// The issue is when the CIE says their is an LSDA. That mandates that every
-/// FDE have an LSDA slot. But if the function does not need an LSDA. There
-/// needs to be some way to signify there is none. The LSDA is encoded as
-/// pc-rel. But you don't look for some magic value after adding the pc. You
-/// have to look for a zero before adding the pc. The problem is that the size
-/// of the zero to look for depends on the encoding. The unwinder bug in SL is
-/// that it always checks for a pointer-size zero. So on x86_64 it looks for 8
-/// bytes of zero. If you have an LSDA, it works fine since the 8-bytes are
-/// non-zero so it goes ahead and then reads the value based on the encoding.
-/// But if you use sdata4 and there is no LSDA, then the test for zero gives a
-/// false negative and the unwinder thinks there is an LSDA.
-///
-/// FIXME: This call-back isn't good! We should be using the correct encoding
-/// regardless of the system. However, there are some systems which have bugs
-/// that prevent this from occuring.
