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 quest...

For any element in a C/C++ source file, I would like to be able to determine the corresponding memory location within its compiled executable. Compiling with debug, and using the resulting DWARF in...

#include <stdio.h> #define A "hello world\n" void main() { printf(A); } $ gcc -gdwarf-4 -g3 a.c \ && gdb -ex 'set confirm off' \ -ex 'break main' \ -ex 'run' \ -ex 'p A...

Looking for ways to see generated assembler of a specific function in my binary (an .so to be exact), just as I can see similar on Compiler Explorer, I found How to disassemble one single function ...

In backtraces produced by perf record --call-graph dwarf and printed by perf script, I am consistently getting wrong addresses for maybe 5% of call stacks, i.e. unwinding fails. One example is my_b...

I am using the Crashlytics in order to report the crash occurs in the iOS app. Here, I want to know how to find the path of these below dwarf folder and file in xcode: DWARF_DSYM_FOLDER_PATH DWAR...

XCode supports those 2 values for this Build Setting: Build Settings > Build Options > Debug Information Format. Could anybody explain the differences?

What's structure of a dsym file generated when build the app. I know it contain DWARF debug info, but what's a dsym file. I want to read the DWARF info in it. Is it just a Mach-O binary file that ...

In gdb how can I discover the value of a variable which displays as optimized out? Presumably the value is being stored in a register, how can I find out which one? Given this simple program (copie...

all, is there a tool to check DWARF version of file? Something like this: $ dwarf_tool binary_name 4

When writing assembly manually with GNU GAS, within a function, I want to set a label such that: GDB won't treat that label as the function name I can use b mylabel to break on the label A simi...

I'm using CMake on MacOS to generate Makefiles for my C++ project. When I build a target (say, test/AsyncTest), I get that target, plus a test/AsyncTest.dSYM/ directory that contains the following:...

I have a C program in file delay.c: void delay(int num) { volatile int i; for(i=0; i<num; i++); } Then I compile the program with gcc 4.6.3 on ARM emulator (armel, more specifically) with c...

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 th...

On OSX when you link a binary from multiple object files like this clang++ -g myfile.cpp -o myfile.o clang++ myfile.o -shared -o myfile.dylib it will generate a .debug_info section (etc.) in myf...

I'm programming in a mix of C, C++ and assembly and I'd like to get reliable backtraces from any part of the code. This mostly works fine for the C and C++ code since I can generate debugging info...

I would like an explanation for the values used with the .cfi_def_cfa_offset directives in assembly generated by GCC. I know vaguely that the .cfi directives are involved in call frames and stack u...

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...

I'm working with DWARF parser that looks for string data in the .debug_str section. In the ELF files I'm parsing, the string data is in the .strtab section. What's the difference between these two ...

GCC 4.8 supports DWARF4. I'm wondering what is the difference between DWARF4 and DWARF2 from user point of view. Lets look at it from GDB point of view. Is there any difference for users when you ...

I've read in a few places that ASLR is supposed to load the .data section at random addresses each time a program is run, which means the addresses of global variables should be different. However,...
