Simplify `vec!` macro by replacing 2 following branches: - `($($x:expr),*) => (...)` - `($($x:expr,)*) => (...)` with one: - `($($x:expr),* $(,)?) => (...)`
Fix regression introduced in commit #3ae2d21
This appears to have never been used ever since its introduction in 61c7569 -- the plugin discussed on the PR introducing that commit, 34811, never materialized. It's also simple to readd in the current scheme, but given that macro expansion is already quite complicated, additional useless state seems good to remove while we're not using it.
Add lang items for methods on raw slices.
It is already possible to extract the pointer part of a raw slice by a simple cast, but retrieving the length is not possible without relying on the representation of the raw slice when it is not valid to convert the raw slice into a slice reference (i.e. the pointer is null or unaligned). Introduce a len() method on raw slices to add this missing feature.

…=oli-obk tighten CTFE safety net for accesses to globals Previously, we only rejected reading from all statics. Now we also reject reading from any mutable global. Mutable globals are the true culprit here as their run-time value might be different from their compile-time values. Statics are just the approximation we use for that so far. Also refactor the code a bit to make it clearer what is being checked and allowed. r? @oli-obk
…etrochenkov simplify `vec!` macro Simplify `vec!` macro by replacing 2 following branches: - `($($x:expr),*) => (...)` - `($($x:expr,)*) => (...)` with one: - `($($x:expr),* $(,)?) => (...)` This is a minor change, however, this will make the documentation cleaner
fix target & runtool args order - `TargetTripple::to_string` converts "path triples" to `<target>-<hash>`, but in this case we need the path. Afaict there is no method to get the real triple other than manually matching - the order of the runtools arguments is inconsistent with the way tests usually pass arguments ie using `runner` key in `.cargo/config`
…SimonSapin ptr: introduce len() method on raw slices It is already possible to extract the pointer part of a raw slice by a simple cast, but retrieving the length is not possible without relying on the representation of the raw slice when it is not valid to convert the raw slice into a slice reference (i.e. the pointer is null or unaligned). ~Introduce a new function ptr::slice_len() to add this missing feature.~ Introduce a len() method on raw slices to add this missing feature.
…petrochenkov Remove unused single_step flag This appears to have never been used ever since its introduction in 61c7569 -- the plugin discussed on the PR introducing that commit, 34811, never materialized. It's also simple to re-add in the current scheme, but given that macro expansion is already quite complicated, additional useless state seems good to remove while we're not using it.
