+
+//
+// A compiler can generated compact unwind information for a function by adding
+// a "row" to the __LD,__compact_unwind section. This section has the
+// S_ATTR_DEBUG bit set, so the section will be ignored by older linkers.
+// It is removed by the new linker, so never ends up in final executables.
+// This section is a table, initially with one row per function (that needs
+// unwind info). The table columns and some conceptual entries are:
+//
+// range-start pointer to start of function/range
+// range-length
+// compact-unwind-encoding 32-bit encoding
+// personality-function or zero if no personality function
+// lsda or zero if no LSDA data
+//
+// The length and encoding fields are 32-bits. The other are all pointer sized.
+//
+// In x86_64 assembly, these entry would look like:
+//
+// .section __LD,__compact_unwind,regular,debug
+//
+// #compact unwind for _foo
+// .quad _foo
+// .set L1,LfooEnd-_foo
+// .long L1
+// .long 0x01010001
+// .quad 0
+// .quad 0
+//
+// #compact unwind for _bar
+// .quad _bar
+// .set L2,LbarEnd-_bar
+// .long L2
+// .long 0x01020011
+// .quad __gxx_personality
+// .quad except_tab1
+//
+//
+// Notes: There is no need for any labels in the the __compact_unwind section.
+// The use of the .set directive is to force the evaluation of the
+// range-length at assembly time, instead of generating relocations.
+//
+// To support future compiler optimizations where which non-volatile registers
+// are saved changes within a function (e.g. delay saving non-volatiles until
+// necessary), there can by multiple lines in the __compact_unwind table for one
+// function, each with a different (non-overlapping) range and each with
+// different compact unwind encodings that correspond to the non-volatiles
+// saved at that range of the function.
+//
+// If a particular function is so wacky that there is no compact unwind way
+// to encode it, then the compiler can emit traditional DWARF unwind info.
+// The runtime will use which ever is available.
+//
+// Runtime support for compact unwind encodings are only available on 10.6
+// and later. So, the compiler should not generate it when targeting pre-10.6.
