[Chapter 6.5] -Zmiri-tag-raw-pointers does not exist anymore #298

Open el-sambal opened 4 months ago

In chapter 6.5 of the book, it says

In fact, this messiness is why there is an extra-experimental extra-strict mode of miri: -Zmiri-tag-raw-pointers.

To enable it, we need to pass it via a MIRIFLAGS environment variable like this:

MIRIFLAGS="-Zmiri-tag-raw-pointers" cargo +nightly-2022-01-21 miri test Or like this on Windows, where you need to just set the variable globally:

$env:MIRIFLAGS="-Zmiri-tag-raw-pointers" cargo +nightly-2022-01-21 miri test

Today I tried running MIRIFLAGS="-Zmiri-tag-raw-pointers" cargo +nightly miri test but Miri says error: unknown unstable option: miri-tag-raw-pointers

According to https://www.ralfj.de/blog/2022/07/02/miri.html, the option miri-tag-raw-pointers does not exist anymore and is currently on-by-default. Maybe this information could be included in the book.

Thanks for having made/making such a useful educational resource!
