2020-07-03Rollup merge of #73670 - davidhewitt:format-args-capture, r=varkorManish Goregaokar-0/+47
Add `format_args_capture` feature This is the initial implementation PR for [RFC 2795](https://github.com/rust-lang/rfcs/pull/2795). Note that, as dicussed in the tracking issue (#67984), the feature gate has been called `format_args_capture`. Next up I guess I need to add documentation for this feature. I've not written any docs before for rustc / std so I would appreciate suggestions on where I should add docs.

Does not yet make its constness stable, though. Use of `Location::caller` in const contexts is still gated by `#![feature(const_caller_location)]`.

Fix handling of reserved registers for ARM inline asm `r6` is now disallowed as an operand since LLVM sometimes uses it as a base pointer. The check against using the frame pointer as an operand now takes the platform into account and will block either `r7` or `r11` as appropriate. Fixes #73450 cc @cbiffle

2020-06-19Rollup merge of #73347 - tmiasko:incompatible-sanitizers, r=nikicManish Goregaokar-2/+1
Diagnose use of incompatible sanitizers Emit an error when incompatible sanitizer are configured through command line options. Previously the last one configured prevailed and others were silently ignored. Additionally use a set to represent configured sanitizers, making it possible to enable multiple sanitizers at once. At least in principle, since currently all of them are considered to be incompatible with others.
2020-06-19Rollup merge of #73364 - joshtriplett:inline-asm, r=AmanieuManish Goregaokar-21/+36
asm: Allow multiple template string arguments; interpret them as newline-separated Allow the `asm!` macro to accept a series of template arguments, and interpret them as if they were concatenated with a '\n' between them. This allows writing an `asm!` where each line of assembly appears in a separate template string argument. This syntax makes it possible for rustfmt to reliably format and indent each line of assembly, without risking changes to the inside of a template string. It also avoids the complexity of having the user carefully format and indent a multi-line string (including where to put the surrounding quotes), and avoids the extra indentation and lines of a call to `concat!`. For example, rewriting the second example from the [blog post on the new inline assembly syntax](https://blog.rust-lang.org/inside-rust/2020/06/08/new-inline-asm.html) using multiple template strings: ```rust fn main() { let mut bits = [0u8; 64]; for value in 0..=1024u64 { let popcnt; unsafe { asm!( " popcnt {popcnt}, {v}", "2:", " blsi rax, {v}", " jz 1f", " xor {v}, rax", " tzcnt rax, rax", " stosb", " jmp 2b", "1:", v = inout(reg) value => _, popcnt = out(reg) popcnt, out("rax") _, // scratch inout("rdi") bits.as_mut_ptr() => _, ); } println!("bits of {}: {:?}", value, &bits[0..popcnt]); } } ``` Note that all the template strings must appear before all other arguments; you cannot, for instance, provide a series of template strings intermixed with the corresponding operands.

2020-06-11Rollup merge of #73230 - Amanieu:asm-unused2, r=petrochenkovDylan DPC-2/+4
Suggest including unused asm arguments in a comment to avoid error We require all arguments to an `asm!` to be used in the template string, just like format strings. However in some cases (e.g. `black_box`) it may be desirable to have `asm!` arguments that are not used in the template string. Currently this is a hard error rather than a lint since `#[allow]` does not work on macros (#63221), so this PR suggests using the unused arguments in an asm comment as a workaround. r? @petrochenkov

2020-06-08Rollup merge of #73001 - ilya-bobyr:master, r=dtolnayRalf Jung-0/+45
Free `default()` forwarding to `Default::default()` It feels a bit redundant to have to say `Default::default()` every time I need a new value of a type that has a `Default` instance. Especially so, compared to Haskell, where the same functionality is called `def`. Providing a free `default()` function that forwards to `Default::default()` seems to improve the situation. The trait is still there, so if someone wants to be explicit and to say `Default::default()` - it still works, but if imported as `std::default::default;`, then the free function reduces typing and visual noise.
