2020-06-19Rollup merge of #73054 - RalfJung:dont-panic, r=Mark-SimulacrumRalf Jung-7/+21
memory access sanity checks: abort instead of panic Suggested by @Mark-Simulacrum, this should help reduce the performance impact of these checks.
2020-06-18Rollup merge of #72279 - RalfJung:raw-ref-macros, r=nikomatsakisManish Goregaokar-0/+67
add raw_ref macros In https://github.com/rust-lang/rust/issues/64490, various people were in favor of exposing `&raw` as a macro first before making the actual syntax stable. So this PR (unstably) introduces those macros. I'll create the tracking issue if we're okay moving forward with this.

2020-06-09[AVR] Fix debug printing of function pointersDylan McKay-2/+12
This commit fixes debug printing of function pointers on AVR. AVR does not support `addrspacecast` instructions, and so this patch modifies libcore so that a `ptrtoint` IR instruction is used and the address space cast is avoided.

2020-05-18Add `len` and `slice_from_raw_parts` to `NonNull<[T]>`Simon Sapin-0/+59
This follows the precedent of the recently-added `<*const [T]>::len` (adding to its tracking issue https://github.com/rust-lang/rust/issues/71146) and `ptr::slice_from_raw_parts`.
2020-05-17make many ptr functions must_useSteve Klabnik-0/+12
https://djugei.github.io/bad-at-unsafe/ describes an error a user had when trying to use offset: > At first I just assumed that the .add() and .offset() methods on pointers would mutate the pointer. They do not. Instead they return a new pointer, which gets dropped silently if you don't use it. Unlike for example Result, which is must_use annotated.

2020-04-23doc-example: Refactor pointer name to avoid confusioncohenarthur-4/+2
Changed raw pointer name from ptr to raw_pointer to avoid confusion with the `use std::ptr` statement a few lines above. This way the crate name and pointer name are well differenciated.

2020-04-14ptr: add tracking issue for len() method on raw slicesMatthias Schiffer-4/+4
2020-04-14ptr: introduce len() method on raw slicesMatthias Schiffer-2/+50
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.
