How to disassemble one single function using objdump?

一个人想着一个人 提交于 2019-11-27 10:54:46
I've got a binary installed on my system, and would like to look at the disassembly of a given function. Preferrably using objdump , but other solutions would be acceptable as well. From this questions I've learned that I might be able to disassemble part of the code if I only know the boundary addresses. From this answer I've learned how to turn my split debug symbols back into a single file. But even operating on that single file, and even disassembling all the code (i.e. without start or stop address, but plain -d parameter to objdump ), I still don't see that symbol anywhere. Which makes

atos and dwarfdump won't symbolicate my address

I received a crash report via AirBrake.io that isn't symbolicated. Since the crash report is not in exactly the same format as an Apple crashlog I can't just drop it on XCode as usual, so I took the exact same build from my XCode archive tried to symbolicate it on the commandline. With the following result: $ atos -o kidsapp.app/kidsapp 0x0002fc4c 0x0002fc4c (in kidsapp) I'm absolutely sure I'm using the same build as the crash report is from. So I also tried with dwarfdump: $ dwarfdump --lookup 0x0002fc4c --arch armv7 kidsapp.app.dSYM ----------------------------------------------------------

Library to read ELF file DWARF debug information

问题 Any recommendations for a good cross-platform library for reading ELF file debug information in DWARF format? I'd like to read the DWARF debug info in a Python program. 回答1: There's a new kid on the block - pyelftools - a pure Python library for parsing the ELF and DWARF formats. Give it a try. It aims to be feature-complete and is currently in active development, so any problems should be handled quickly and enthusiastically :-) 回答2: The concept of "ELF debug info" doesn't really exist: the

where/how does Apples GCC store DWARF inside an executable

问题 Where/how does Apples GCC store DWARF inside an executable? I compiled a binary via gcc -gdwarf-2 (Apples GCC). However, neither objdump -g nor objdump -h does show me any debug information. Also libbfd does not find any debug information. (I asked on the binutils-mailinglist about it here.) I am able however to extract the debugging information via dsymutil (into a dSYM). libbfd is also able to read those debug info then. 回答1: On Mac OS X there was a decision to have the linker ( ld ) not
