Use Try syntax for Option in place of macros or match

2017-12-09T22:18:33+00:00

use field init shorthand EVERYWHERE

2017-08-15T22:29:17+00:00

Like #43008 (f668999), but _much more aggressive_.

Removed as many "```ignore" as possible.

2017-06-23T07:31:53+00:00

Replaced by adding extra imports, adding hidden code (`# ...`), modifying examples to be runnable (sorry Homura), specifying non-Rust code, and converting to should_panic, no_run, or compile_fail. Remaining "```ignore"s received an explanation why they are being ignored.

Bump version, upgrade bootstrap

2017-02-03T21:25:46+00:00

This commit updates the version number to 1.17.0 as we're not on that version of the nightly compiler, and at the same time this updates src/stage0.txt to bootstrap from freshly minted beta compiler and beta Cargo.

Implement emit_iu128 for json serialiser

2016-12-30T14:17:26+00:00

Causes ICEs otherwise while trying to dump AST

Such large. Very 128. Much bits.

2016-12-30T14:15:44+00:00

This commit introduces 128-bit integers. Stage 2 builds and produces a working compiler which understands and supports 128-bit integers throughout. The general strategy used is to have rustc_i128 module which provides aliases for iu128, equal to iu64 in stage9 and iu128 later. Since nowhere in rustc we rely on large numbers being supported, this strategy is good enough to get past the first bootstrap stages to end up with a fully working 128-bit capable compiler. In order for this strategy to work, number of locations had to be changed to use associated max_value/min_value instead of MAX/MIN constants as well as the min_value (or was it max_value?) had to be changed to use xor instead of shift so both 64-bit and 128-bit based consteval works (former not necessarily producing the right results in stage1). This commit includes manual merge conflict resolution changes from a rebase by @est31.

Changed most vec! invocations to use square braces

2016-10-31T22:51:40+00:00

Most of the Rust community agrees that the vec! macro is clearer when called using square brackets [] instead of regular brackets (). Most of these ocurrences are from before macros allowed using different types of brackets. There is one left unchanged in a pretty-print test, as the pretty printer still wants it to have regular brackets.

Avoid allocations in `Decoder::read_str`.

2016-10-09T23:36:35+00:00

`opaque::Decoder::read_str` is very hot within `rustc` due to its use in the reading of crate metadata, and it currently returns a `String`. This commit changes it to instead return a `Cow`, which avoids a heap allocation. This change reduces the number of calls to `malloc` by almost 10% in some benchmarks. This is a [breaking-change] to libserialize.

[breaking-change] std: change `encode_utf{8,16}()` to take a buffer and return a slice

2016-09-28T07:03:30+00:00

They panic if the buffer is too small.

Use question_mark feature in libserialize.
