The second commit in this PR will stop printing the macro definition site in backtraces, which cuts their length in half and increases readability (the definition site was only correct for local macros). The third commit will not print an invocation if the last one printed occurred at the same place (span). This will make backtraces caused by a self-recursive macro much shorter. (A possible alternative would be to capture the backtrace first, then limit it to a few frames at the start and end of the chain and print `...` inbetween. This would also work with multiple macros calling each other, which is not addressed by this PR - although the backtrace will still be halved) Example: ```rust macro_rules! m { ( 0 $($t:tt)* ) => ( m!($($t)*); ); () => ( fn main() {0} ); } m!(0 0 0 0 0 0 0 0 0 0 0 0 0 0 0); ``` On a semi-recent nightly, this yields: ``` test.rs:3:21: 3:22 error: mismatched types: expected `()`, found `_` (expected (), found integral variable) [E0308] test.rs:3 () => ( fn main() {0} ); ^ test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:2:23: 2:34 note: expansion site test.rs:1:1: 4:2 note: in expansion of m! test.rs:6:1: 6:35 note: expansion site test.rs:3:21: 3:22 help: run `rustc --explain E0308` to see a detailed explanation error: aborting due to previous error ``` After this patch: ``` test.rs:3:21: 3:22 error: mismatched types: expected `()`, found `_` (expected (), found integral variable) [E0308] test.rs:3 () => ( fn main() {0} ); ^ test.rs:2:23: 2:34 note: in this expansion of m! test.rs:6:1: 6:35 note: in this expansion of m! test.rs:3:21: 3:22 help: run `rustc --explain E0308` to see a detailed explanation error: aborting due to previous error ```

This patch transforms functions of the form ``` fn f<Generic: AsRef<Concrete>>(arg: Generic) { let arg: &Concrete = arg.as_ref(); // Code using arg } ``` to the next form: ``` #[inline] fn f<Generic: AsRef<Concrete>>(arg: Generic) { fn f_inner(arg: &Concrete) { // Code using arg } f_inner(arg.as_ref()); } ``` Therefore, most of the code is concrete and not duplicated during monomorphisation (unless inlined) and only the tiny bit of conversion code is duplicated. This method was mentioned by @aturon in the Conversion Traits RFC (https://github.com/rust-lang/rfcs/blame/master/text/0529-conversion-traits.md#L249) and similar techniques are not uncommon in C++ template libraries. This patch goes to the extremes and applies the transformation even to smaller functions<sup>1</sup> for purity of the experiment. *Some of them can be rolled back* if considered too ridiculous. <sup>1</sup> However who knows how small are these functions are after inlining and everything. The functions in question are mostly `fs`/`os` functions and not used especially often with variety of argument types, so the code size reduction is rather small (but consistent). Here are the sizes of stage2 artifacts before and after the patch: https://gist.github.com/petrochenkov/e76a6b280f382da13c5d https://gist.github.com/petrochenkov/6cc28727d5256dbdfed0 Note: All the `inner` functions are concrete and unavailable for cross-crate inlining, some of them may need `#[inline]` annotations in the future. r? @aturon

Overflows in integer pow() computations would be missed if they preceded a 0 bit of the exponent being processed. This made calls such as 2i32.pow(1024) not trigger an overflow. Fixes #28012

This allows to skip the codegen for all the unneeded landing pads, reducing code size across the board by about 2-5%, depending on the crate. Compile times seem to be pretty unaffected though :-/

Unwinding across an FFI boundary is undefined behaviour, so we can mark all external function as nounwind. The obvious exception are those functions that actually perform the unwinding.

In addition to instruction updates I - changed from wget to curl, because curl is a prerequisite of rust itself - removed `[...]` because they're missing from so many places it would just obscure the instructions if they were all put in r? @steveklabnik

There is already a corresponding impl for `std::io::Write`. This change will make the two traits more consistent.

This changes libfmt_macros `CharIndices` iterator into `Peekable` so it can be used without `.clone()`. Also changed some `loop match` and `match` to `while let` and `if let` respectively (mostly for readability).

This fixes the ICE, and makes it just a compiler error/warning. I'm not exactly sure that's whats wanted, so tell me if it isn't.

Technically a [breaking-change], but the broken code is useless, like `i32<Param=()>`. Fixes #24682
