stack backtrace #105

Open Godones opened 1 year ago

Godones commented 1 year ago
  1. Update the stack backtrace method
  2. Turn off the -C force-frame-pointers flag, which may cause unnecessary overhead.
  3. The new method should be able to run normally on the alloc-enabled branch

A simple test looks like this:

[kernel] Panicked at src/mm/page_table.rs:178 translated_str: not implemented
---START BACKTRACE---
0x80010a64 (+638) backtrace

---END   BACKTRACE---
