What's Wrong?

#22683
When compiling for the ARM version with use_unwind=off, but get_stack_trace still defaults to using libunwind for stack trace printing.

std::string get_stack_trace(int start_pointers_index, std::string dwarf_location_info_mode) {
#ifdef ENABLE_STACKTRACE
if (dwarf_location_info_mode.empty()) {
dwarf_location_info_mode = config::dwarf_location_info_mode;
}
auto tool = config::get_stack_trace_tool;
if (tool == "glog") {
return get_stack_trace_by_glog();
} else if (tool == "boost") {
return get_stack_trace_by_boost();
} else if (tool == "glibc") {
return get_stack_trace_by_glibc();
} else if (tool == "libunwind") {
#if defined(APPLE) // TODO
return get_stack_trace_by_glog();
#endif
return get_stack_trace_by_libunwind(start_pointers_index, dwarf_location_info_mode);
} else {
return "no stack";
}
#endif
return "no enable stack";
}

What You Expected?

USE_UNWIND is effective in StackTrace::tryCapture().
For ARM, although get_stack_trace_by_libunwind is called, the standard backtrace function from execinfo.h is actually used instead of unw_backtrace, regardless of whether USE_UNWIND is ON or OFF.
