-## Debugging (host code)
-
-Ignoring SIGSEGV when debugging in host:
-
-- **gdb**: `handle all nostop pass`.
-- **lldb**: `pro hand -p true -s false -n false SIGSEGV`.
-
-## Debugging (guest code)
-
-### gdb
-
-Run `./build/bin/eden-cli -c <path to your config file (see logs where you run eden normally to see where it is)> -d -g <path to game>`
-
-Then hook up an aarch64-gdb (use `yay aarch64-gdb` or `sudo pkg in arch64-gdb` to install)
-Then type `target remote localhost:1234` and type `c` (for continue) - and then if it crashes just do a `bt` (backtrace) and `layout asm`.
-
-### gdb cheatsheet
-
-- `mo <cmd>`: Monitor commands, `get info`, `get fastmem` and `get mappings` are available. Type `mo help` for more info.
-- `detach`: Detach from remote (i.e restarting the emulator).
-- `c`: Continue
-- `p <expr>`: Print variable, `p/x <expr>` for hexadecimal.
-- `r`: Run
-- `bt`: Print backtrace
-- `info threads`: Print all active threads
-- `thread <number>`: Switch to the given thread (see `info threads`)
-- `layout asm`: Display in assembly mode (TUI)
-- `si`: Step assembly instruction
-- `s` or `step`: Step over LINE OF CODE (not assembly)
-- `display <expr>`: Display variable each step.
-- `n`: Next (skips over call frame of a function)
-- `frame <number>`: Switches to the given frame (from `bt`)
-- `br <expr>`: Set breakpoint at `<expr>`.
-- `delete`: Deletes all breakpoints.
-- `catch throw`: Breakpoint at throw. Can also use `br __cxa_throw`
-- `br _mesa_error`: Break on mesa errors (set environment variable `MESA_DEBUG=1` beforehand), see [MESA_DEBUG](https://mesa-docs.readthedocs.io/en/latest/debugging.html).
-
-Expressions can be `variable_names` or `1234` (numbers) or `*var` (dereference of a pointer) or `*(1 + var)` (computed expression).

-For more information type `info gdb` and read [the man page](https://man7.org/linux/man-pages/man1/gdb.1.html).

 # Bisecting older commits
 
 Since going into the past can be tricky (especially due to the dependencies from the project being lost thru time). This should "restore" the URLs for the respective submodules.
