2015-09-20Rollup merge of #28526 - Manishearth:expand-clone, r=eddybManish Goregaokar-24/+25
This reduces some clones of `Vec`s. These are not deep copies since the token tree is made using `Rc`s, so this won't be a major improvement. r? @eddyb

This could be a [breaking-change] if your lint or syntax extension (is that even possible?) uses HIR attributes or literals.
2015-09-15Auto merge of #28351 - jonas-schievink:macro-bt, r=nrcbors-22/+37
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 ```

2015-09-14Auto merge of #28358 - dotdash:nounwind, r=alexcrichtonbors-0/+4
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 :-/

2015-09-13Auto merge of #28286 - matklad:remove-dead-code, r=eddybbors-38/+31
There is a dead code in libsyntax/parser/parse.rs, when parsing structs. Two functions are involved: * [parse_item_struct](https://github.com/rust-lang/rust/blob/cd9c9f048f6aa0be091cd9835771ba0712bead4e/src/libsyntax/parse/parser.rs#L4691) * [parse_tuple_struct_body](https://github.com/rust-lang/rust/blob/cd9c9f048f6aa0be091cd9835771ba0712bead4e/src/libsyntax/parse/parser.rs#L4769) The problem is that both functions handle the case with unit structs. But because `parse_tuple_struct_body` is called from `parse_item_struct`, it never faces this case. This PR removes unit struct case from `parse_tuple_struct_body` function. I tested with `make -j8 check-statge1`.

2015-09-10Don't print the macro definition site in backtracesJonas Schievink-6/+2
This halves the backtrace length. The definition site wasn't very useful anyways, since it may be invalid (for compiler expansions) or located in another crate. Since the macro name is still printed, grepping for it is still an easy way of finding the definition.

2015-09-07libsyntax: remove dead code from parser.rsAleksey Kladov-35/+24
Both `parse_tuple_struct_body` and `parse_item_struct` handled the case of unit like struct. The redundancy is removed, `parse_tuple_struct_body` now handles only real tuple structs.

2015-09-04Auto merge of #28034 - alexcrichton:new-lines, r=aturonbors-1/+1
This commit is an implementation of [RFC 1212][rfc] which tweaks the behavior of the `str::lines` and `BufRead::lines` iterators. Both iterators now account for `\r\n` sequences in addition to `\n`, allowing for less surprising behavior across platforms (especially in the `BufRead` case). Splitting *only* on the `\n` character can still be achieved with `split('\n')` in both cases. The `str::lines_any` function is also now deprecated as `str::lines` is a drop-in replacement for it. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1212-line-endings.md Closes #28032
