-// 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.
