--// the common prefixes of each symbol name are shared for a more compact
--// representation. The prefixes are stored on the edges of the trie, and one
--// edge can represent multiple characters. For example, given two exported

--// +-+-+

--// +-+-+

--// This file contains functions to parse Mach-O object files. In this comment,
--// we describe the Mach-O file structure and how we parse it.
--//
--// Mach-O is not very different from ELF or COFF. The notion of symbols,
--// sections and relocations exists in Mach-O as it does in ELF and COFF.
--//
--// Perhaps the notion that is new to those who know ELF/COFF is "subsections".
--// In ELF/COFF, sections are an atomic unit of data copied from input files to
--// output files. When we merge or garbage-collect sections, we treat each
--// section as an atomic unit. In Mach-O, that's not the case. Sections can
--// consist of multiple subsections, and subsections are a unit of merging and
--// garbage-collecting. Therefore, Mach-O's subsections are more similar to
--// ELF/COFF's sections than Mach-O's sections are.
--//
--// A section can have multiple symbols. A symbol that does not have the
--// N_ALT_ENTRY attribute indicates a beginning of a subsection. Therefore, by
--// definition, a symbol is always present at the beginning of each subsection. A
--// symbol with N_ALT_ENTRY attribute does not start a new subsection and can
--// point to a middle of a subsection.
--//
--// The notion of subsections also affects how relocations are represented in
--// Mach-O. All references within a section need to be explicitly represented as
--// relocations if they refer to different subsections, because we obviously need
--// to fix up addresses if subsections are laid out in an output file differently
--// than they were in object files. To represent that, Mach-O relocations can
--// refer to an unnamed location via its address. Scattered relocations (those
--// with the R_SCATTERED bit set) always refer to unnamed locations.
--// Non-scattered relocations refer to an unnamed location if r_extern is not set
--// and r_symbolnum is zero.
--//
--// Without the above differences, I think you can use your knowledge about ELF
--// and COFF for Mach-O.

++// are encoded in the UNWIND_X86_EBP_FRAME_REGISTERS bits as five 3-bit entries.
++// Each entry contains which register to restore.
++// UNWIND_X86_MODE_STACK_IMMD:
++// A "frameless" (EBP not used as frame pointer) function with a small
++// constant stack size. To return, a constant (encoded in the compact
++// unwind encoding) is added to the ESP. Then the return is done by
++// popping the stack into the pc.

++// on the stack immediately after the return address. The stack_size/4 is
++// encoded in the UNWIND_X86_FRAMELESS_STACK_SIZE (max stack size is 1024).
++// The number of registers saved is encoded in UNWIND_X86_FRAMELESS_STACK_REG_COUNT.
++// UNWIND_X86_FRAMELESS_STACK_REG_PERMUTATION constains which registers were

++// A "frameless" (EBP not used as frame pointer) function large constant
++// stack size. This case is like the previous, except the stack size is too
++// large to encode in the compact unwind encoding. Instead it requires that
++// the function contains "subl $nnnnnnnn,ESP" in its prolog. The compact
++// encoding contains the offset to the nnnnnnnn value in the function in
++// UNWIND_X86_FRAMELESS_STACK_SIZE.
++// UNWIND_X86_MODE_DWARF:
++// No compact unwind encoding is available. Instead the low 24-bits of the
++// compact encoding is the offset of the DWARF FDE in the __eh_frame section.
++// This mode is never used in object files. It is only generated by the

++//
++////////////////////////////////////////////////////////////////////////////////
++
++//
++// 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.
