Objective-C data structures. This is allows tools such as darwin's otool(1) that uses the LLVM disassembler take a pointer value being loaded by an instruction and add a comment to what it is being referenced to make following disassembly of Objective-C programs more readable. For example disassembling the Mac OS X TextEdit app one will see comments like the following: movq 0x20684(%rip), %rsi ## Objc selector ref: standardUserDefaults movq 0x21985(%rip), %rdi ## Objc class ref: _OBJC_CLASS_$_NSUserDefaults movq 0x1d156(%rip), %r14 ## Objc message: +[NSUserDefaults standardUserDefaults] leaq 0x23615(%rip), %rdx ## Objc cfstring ref: @"SelectLinePanel" callq 0x10001386c ## Objc message: -[[%rdi super] initWithWindowNibName:] These diffs also include putting quotes around C strings in literal pools and uses "symbol address" in the comment when adding a symbol name to the comment to tell these types of references apart: leaq 0x4f(%rip), %rax ## literal pool for: "Hello world" movq 0x1c3ea(%rip), %rax ## literal pool symbol address: ___stack_chk_guard Of course the easy changes are in the LLVM disassembler and the hard work is up to the implementer of the SymbolLookUp() call back. rdar://10602439 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193833 91177308-0d34-0410-b5e6-96231b3b80d8 |
