2016-10-22Auto merge of #37318 - nnethercote:html5ever-more, r=nrc,eddybbors-7/+12
Avoid some allocations in the macro parser These three commits reduce the number of heap allocations done when compiling rustc-benchmarks/html5ever-2016-08-25 by 20%, from 16.5M to 13.3M. This speeds up (debug) compilation of it with a stage1 compiler by about 7%.
2016-10-21Replace the `String` in `ParseResult::Failure` with `Token`.Nicholas Nethercote-7/+12
This lets us delay creation of failure messages until they are needed, which avoids ~1.6M allocations in html5ever.
2016-10-21Avoid an unnecessary clone in `generic_extensions`.Nicholas Nethercote-2/+2
This avoids ~800,000 allocations in html5ever.
2016-10-19Improve `$crate`.Jeffrey Seyfried-9/+3
2016-10-14Avoid many CrateConfig clones.Nicholas Nethercote-2/+2
This commit changes `ExtCtx::cfg()` so it returns a `CrateConfig` reference instead of a clone. As a result, it also changes all of the `cfg()` callsites to explicitly clone... except one, because the commit also changes `macro_parser::parse()` to take `&CrateConfig`. This is good, because that function can be hot, and `CrateConfig` is expensive to clone. This change almost halves the number of heap allocations done by rustc for `html5ever` in rustc-benchmarks suite, which makes compilation 1.20x faster.
2016-09-28Rollup merge of #36789 - jseyfried:non_inline_mod_in_block, r=nikomatsakisJonathan Turner-1/+1
Allow more non-inline modules in blocks Currently, non-inline modules without a `#[path]` attribute are not allowed in blocks. This PR allows non-inline modules that have an ancestor module with a `#[path]` attribute, provided there is not a nearer ancestor block. For example, ```rust fn main() { #[path = "..."] mod foo { mod bar; //< allowed by this PR fn f() { mod bar; //< still an error } } } ``` Fixes #36772. r? @nikomatsakis

2016-09-26Rollup merge of #36721 - TimNN:infinite-emptiness, r=nrcJonathan Turner-1/+38
