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.

2020-04-23doc-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.

- As explained in the comment inside mod_inv, it is valid to work mod `usize::max_value()` right until the end.

- When calculating the inverse, it's enough to work `mod a/g` instead of `mod a`.

2020-01-28Auto merge of #68234 - CAD97:slice-from-raw-parts, r=KodrAusbors-6/+5
Stabilize ptr::slice_from_raw_parts[_mut] Closes #36925, the tracking issue. Initial impl: #60667 r? @rust-lang/libs In addition to stabilizing, I've adjusted the example of `ptr::slice_from_raw_parts` to use `slice_from_raw_parts` instead of `slice_from_raw_parts_mut`, which was unnecessary for the example as written.

2019-12-22Rollup merge of #67480 - rossmacarthur:fix-41260-avoid-issue-0-part-2, r=CentrilMazdak Farrokhzad-1/+1
Require issue = "none" over issue = "0" in unstable attributes These changes make the use of `issue = "none"` required in unstable attributes throughout the compiler. Notes: - #66299 is now in beta so `issue = "none"` is accepted. - The `tidy` tool now fails on `issue = "0"`. - Tests that used `issue = "0"` were changed to use `issue = "none"`, except for _one_ that asserts `issue = "0"` can still be used. - The compiler still allows `issue = "0"` because some submodules require it, this could be disallowed once these are updated.

Make ptr::slice_from_raw_parts a const fn available under a feature flag A first step in the direction of https://github.com/rust-lang/rust/issues/67456 . This makes `ptr::slice_from_raw_parts` and `ptr::slice_from_raw_parts_mut` available as a const fn under a feature flag.

Have tidy ensure that we document all `unsafe` blocks in libcore cc @rust-lang/libs I documented a few and added ignore flags on the other files. We can incrementally document the files, but won't regress any files this way.
