2014-07-03Simplify PatIdent to contain an Ident rather than a PathJohn Clements-34/+12
Rationale: for what appear to be historical reasons only, the PatIdent contains a Path rather than an Ident. This means that there are many places in the code where an ident is artificially promoted to a path, and---much more problematically--- a bunch of elements from a path are simply thrown away, which seems like an invitation to some really nasty bugs. This commit replaces the Path in a PatIdent with a SpannedIdent, which just contains an ident and a span.
2014-06-29Implement RFC#28: Add PartialOrd::partial_cmpSteven Fackler-5/+99
I ended up altering the semantics of Json's PartialOrd implementation. It used to be the case that Null < Null, but I can't think of any reason for an ordering other than the default one so I just switched it over to using the derived implementation. This also fixes broken `PartialOrd` implementations for `Vec` and `TreeMap`. RFC: 0028-partial-cmp
2014-06-28auto merge of #15233 : jbclements/rust/match-var-hygiene-etc, r=cmrbors-98/+137
This PR includes two big things and a bunch of little ones. 1) It enables hygiene for variables bound by 'match' expressions. 2) It fixes a bug discovered indirectly (#15221), wherein fold traversal failed to visit nonterminal nodes. 3) It fixes a small bug in the macro tutorial. It also adds tests for the first two, and makes a bunch of small comment improvements and cleanup.

2014-06-25auto merge of #15160 : alexcrichton/rust/remove-f128, r=brsonbors-1/+0
The f128 type has very little support in the compiler and the feature is basically unusable today. Supporting half-baked features in the compiler can be detrimental to the long-term development of the compiler, and hence this feature is being removed.

2014-06-18Revert bytes!() docstring change, and fix a typo.Simon Sapin-1/+1
2014-06-18Deprecate the bytes!() macro.Simon Sapin-0/+8
Replace its usage with byte string literals, except in `bytes!()` tests. Also add a new snapshot, to be able to use the new b"foo" syntax. The src/etc/2014-06-rewrite-bytes-macros.py script automatically rewrites `bytes!()` invocations into byte string literals. Pass it filenames as arguments to generate a diff that you can inspect, or `--apply` followed by filenames to apply the changes in place. Diffs can be piped into `tip` or `pygmentize -l diff` for coloring.
2014-06-18auto merge of #14880 : SimonSapin/rust/byte-literals, r=alexcrichtonbors-0/+7
See #14646 (tracking issue) and rust-lang/rfcs#69. This does not close the tracking issue, as the `bytes!()` macro still needs to be removed. It will be later, after a snapshot is made with the changes in this PR, so that the new syntax can be used when bootstrapping the compiler.

2014-06-17librustc: Make addresses of immutable statics insignificant unlessPatrick Walton-9/+1
`#[inline(never)]` is used. Closes #8958. This can break some code that relied on the addresses of statics being distinct; add `#[inline(never)]` to the affected statics. [breaking-change]

2014-06-14rustc: Obsolete the `@` syntax entirelyAlex Crichton-6/+11
This removes all remnants of `@` pointers from rustc. Additionally, this removes the `GC` structure from the prelude as it seems odd exporting an experimental type in the prelude by default. Closes #14193 [breaking-change]

the leading quote part of the identifier for the purposes of hygiene. This adopts @jbclements' solution to #14539. I'm not sure if this is a breaking change or not. Closes #12512. [breaking-change]
