//
// Relocatable Object Files: __LD,__compact_unwind
//
////////////////////////////////////////////////////////////////////////////////
//
// 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.
