How to get the instruction address in ELF from backtrace? #1068
Description
When I use this function to retrieve the backtrace, I only obtain the instrumented addresses.
void print_bt() {
void* frames[10];
int num_frames = backtrace_aarch64(frames, 10);
for (int i = 0; i < num_frames; i++) {
gchar *symbol_name = gum_symbol_name_from_address(frames[i]);
printf(" #%d: 0x%p, %s\n", i, frames[i], symbol_name);
}
}
like this:
#0: 0x0xfffff6fa9e48, print_bt
#2: 0x0xfffff6feaf90, gum_stalker_invoke_callout
#3: 0x0xfffff31653dc, (null)
#4: 0x0xfffff6fad13c, on_main
#5: 0x0xfffff6d5610c, (null)
#6: 0x0xfffff6fad1e0, on_libc_start_main
#7: 0x0xfffff6d5600c, (null)
How can I translate 0x0xfffff31653dc to the origin address in ELF ? maybe a API to access the GumExecFrame ?
