-# Back
-
-Backtraces for Odin, see examples below and in the examples folder.
-
-To change the size (amount of stackframes to print) in places where this can't be set directly, you can use the `-define:BACKTRACE_SIZE=16`.
-
-## Targets
-
-### Windows, MacoOS & Linux
-
-These targets use debug information that's added by compiling with `-debug` to provide traces and give rough information when compiled without it.
-
-Performance is not impacted at all during normal running, just when you ask for a trace or lines.
-
-Per platform notes below:
-
-#### Windows
-
-For Windows support, all credit goes to [DaseinPhaos/pdb](https://github.com/DaseinPhaos/pdb).
-
-Windows is not able to get *any* information when not compiled with `-debug`.
-
-NOTE: The pdb package allocates a lot of stuff and does not really provide a way of deleting the allocations, so, before calling into the package, this package sets it to use the `context.temporary_allocator`.
-
-#### MacOS
-
-Uses a private framework for symbolication, and thus will not get through Apple's review process.
-
-#### Linux
-
-On Linux, the `addr2line` command is invoked, which comes pre-installed (maybe in binutils).
-
-The `addr2line` command can be changed by setting the `-define:BACK_ADDR2LINE_PATH=your/atos` flag.
-
-The path to the running binary is also needed for this command, this is `os.args[0]` by default and to my knowledge is always correct.
-Nevertheless it can be changed with the `-define:BACK_PROGRAM=path/to/binary` flag.
-
-I am planning on rewriting this implementation to not require an external command like this by parsing the DWARF debug information manually.
-
-### Others
-
-Other targets use the instrumentation features of Odin to keep track of stack frames, this has a minimal impact on performance and size.
-
-Forcing the instrumentation based implementation on Windows, Linux and Darwin can be done with `-define:BACK_FORCE_FALLBACK=true`.
-
-NOTE: this implementation requires at least `-o:minimal` as it requires `#force_inline` procs to actually be inlined, this is not the case with `-o:none`.
-
-NOTE: the instrumentation features and WASM combination is a bit fragile and seems to only work on `-o:minimal` exclusively, this is almost certainly a codegen bug.
-
