2017-08-27Prepare the 1.20.0 stable releaseAlex Crichton-1/+1
This prepares the tree for the 1.20.0 stable release. The `cargo` submodule is already updated to the tip of rust-1.20.0 so this just updates the channel we're built in.

2017-08-23std: Mark allocation functions as nounwindAlex Crichton-0/+66
This commit flags all allocation-related functions in liballoc as "this can't unwind" which should largely resolve the size-related issues found on #42808. The documentation on the trait was updated with such a restriction (they can't panic) as well as some other words about the relative instability about implementing a bullet-proof allocator. Closes #42808
2017-08-23fix other cases of registering obligations in a snapshotAriel Ben-Yehuda-9/+7
No test cases for these ones, but they would all ICE if they ever run with a non-empty set of obligations.
2017-08-23register fn-ptr coercion obligations out of a snapshotAriel Ben-Yehuda-2/+20
Fixes #43923.
2017-08-23ast_validation: forbid "nonstandard" literal patternsAriel Ben-Yehuda-6/+44
Since #42886, macros can create "nonstandard" PatKind::Lit patterns, that contain path expressions instead of the usual literal expr. These can cause trouble, including ICEs. We *could* map these nonstandard patterns to PatKind::Path patterns during HIR lowering, but that would be much effort for little gain, and I think is too risky for beta. So let's just forbid them during AST validation. Fixes #43250.
2017-08-23std: Respect formatting flags for str-like OsStrAlex Crichton-6/+29
Historically many `Display` and `Debug` implementations for `OsStr`-like abstractions have gone through `String::from_utf8_lossy`, but this was updated in #42613 to use an internal `Utf8Lossy` abstraction instead. This had the unfortunate side effect of causing a regression (#43765) in code which relied on these `fmt` trait implementations respecting the various formatting flags specified. This commit opportunistically adds back interpretation of formatting trait flags in the "common case" where where `OsStr`-like "thing" is all valid utf-8 and can delegate to the formatting implementation for `str`. This doesn't entirely solve the regression as non-utf8 paths will format differently than they did before still (in that they will not respect formatting flags), but this should solve the regression for all "real world" use cases of paths and such. The door's also still open for handling these flags in the future! Closes #43765
2017-08-23make `for_all_relevant_impls` O(1) againAriel Ben-Yehuda-138/+77
A change in #41911 had made `for_all_relevant_impls` do a linear scan over all impls, instead of using an HashMap. Use an HashMap again to avoid quadratic blowup when there is a large number of structs with impls. I think this fixes #43141 completely, but I want better measurements in order to be sure. As a perf patch, please don't roll this up.

2017-08-13syntax: avoid loading the same source-file multiple timesAriel Ben-Yehuda-3/+7
We already had a cache for file contents, but we read the source-file before testing the cache, causing obvious slowness, so this just avoids loading the source-file when the cache already has the contents.

2017-07-17Auto merge of #42711 - Firstyear:san-on-dylib, r=alexcrichtonbors-23/+205
Add support for dylibs with Address Sanitizer Many applications use address sanitizer to assert correct behaviour of their programs. When using Rust with C, it's much more important to assert correct programs with tools like asan/lsan due to the unsafe nature of the access across an ffi boundary. However, previously only rust bin types could use asan. This posed a challenge for existing C applications that link or dlopen .so when the C application is compiled with asan. This PR enables asan to be linked to the dylib and cdylib crate type. We alter the test to check the proc-macro crate does not work with -Z sanitizer=address. Finally, we add a test that compiles a shared object in rust, then another rust program links it and demonstrates a crash through the call to the library. This PR is nearly complete, but I do require advice on the change to fix the -lasan that currently exists in the dylib test. This is required because the link statement is not being added correctly to the rustc build when -Z sanitizer=address is added (and I'm not 100% sure why) Thanks,

2017-07-17Move resolve diagnostic instability to compile-failOliver Schneider-37/+70
The produced paths aren't stable between builds, since reporting paths inside resolve, before resolve is finished might produce paths resolved to type aliases instead of the concrete type. Compile-fail tests can match just parts of messages, so they don't "suffer" from this issue. This is just a workaround, the instability should be fixed in the future.

2017-07-17Auto merge of #43055 - est31:stabilize_float_bits_conv, r=sfacklerbors-9/+4
Stabilize float_bits_conv for Rust 1.21 Stabilizes the `float_bits_conv` lib feature for the 1.20 release of Rust. I've initially implemented the feature in #39271 and later made PR #43025 to output quiet NaNs even on platforms with different encodings, which seems to have been the only unresolved issue of the API. Due to PR #43025 being only applied to master this stabilisation can't happen for Rust 1.19 through the usual "stabilisation on beta" system that is being done for library APIs. r? @BurntSushi closes #40470.
