When activated the compiler will depend on `jemalloc-sys`, instruct jemalloc to unprefix its symbols, and then link to it. The feature is activated by default on Linux/OSX compilers for x86_64/i686 platforms, and it's not enabled anywhere else for now. We may be able to opt-in other platforms in the future! Also note that the opt-in only happens on CI, it's otherwise unconditionally turned off by default.

This removes OpenSSL build logic from the bootstrap code, and otherwise requests that even on OSX we build curl statically. 2018-09-28T13:55:18+00:00 Christian Poveda christianpoveda@protonmail.com 2018-09-28T07:07:44+00:00 urn:sha1:0724ed68bb0c6c5be89753f1da13ea27dfe2301d 2018-05-09T21:45:34+00:00 Alex Crichton alex@alexcrichton.com 2018-04-24T15:34:14+00:00 urn:sha1:7e5b9ac41e36b29d5208f4e5455aade07d4d107d Currently on CI we predominately compile LLVM with the default system compiler which means gcc on Linux, some version of Clang on OSX, MSVC on Windows, and gcc on MinGW. This commit switches Linux, OSX, and Windows to all use Clang 6.0.0 to build LLVM (aka the C/C++ compiler as part of the bootstrap). This looks to generate faster code according to #49879 which translates to a faster rustc (as LLVM internally is faster) The major changes here were to the containers that build Linux releases, basically adding a new step that uses the previous gcc 4.8 compiler to compile the next Clang 6.0.0 compiler. Otherwise the OSX and Windows scripts have been updated to download precompiled versions of Clang 6 and configure the build to use them. Note that `cc` was updated here to fix using `clang-cl` with `cc-rs` on MSVC, as well as an update to `sccache` on Windows which was needed to correctly work with `clang-cl`. Finally the MinGW compiler is entirely left out here intentionally as it's currently thought that Clang can't generate C++ code for MinGW and we need to use gcc, but this should be verified eventually. 2018-03-21T21:28:11+00:00 kennytm kennytm@gmail.com 2018-03-21T20:07:29+00:00 urn:sha1:56a19a9eec0ae2cd1b1914cfe9854e1c1028f329 2018-03-21T21:28:04+00:00 kennytm kennytm@gmail.com 2018-03-21T18:29:01+00:00 urn:sha1:78bcbb0f96e3c65742fe3f6c5fb4c68f28dcf99c The former seems much more stable, in case the cache becomes invalidated. 2018-03-04T04:21:35+00:00 Alex Crichton alex@alexcrichton.com 2017-08-27T01:30:12+00:00 urn:sha1:d69b24805b5071e5ec9e62d2777a761723644144 This commit imports the LLD project from LLVM to serve as the default linker for the `wasm32-unknown-unknown` target. The `binaryen` submoule is consequently removed along with "binaryen linker" support in rustc. Moving to LLD brings with it a number of benefits for wasm code: * LLD is itself an actual linker, so there's no need to compile all wasm code with LTO any more. As a result builds should be *much* speedier as LTO is no longer forcibly enabled for all builds of the wasm target. * LLD is quickly becoming an "official solution" for linking wasm code together. This, I believe at least, is intended to be the main supported linker for native code and wasm moving forward. Picking up support early on should help ensure that we can help LLD identify bugs and otherwise prove that it works great for all our use cases! * Improvements to the wasm toolchain are currently primarily focused around LLVM and LLD (from what I can tell at least), so it's in general much better to be on this bandwagon for bugfixes and new features. * Historical "hacks" like `wasm-gc` will soon no longer be necessary, LLD will [natively implement][gc] `--gc-sections` (better than `wasm-gc`!) which means a postprocessor is no longer needed to show off Rust's "small wasm binary size". LLD is added in a pretty standard way to rustc right now. A new rustbuild target was defined for building LLD, and this is executed when a compiler's sysroot is being assembled. LLD is compiled against the LLVM that we've got in tree, which means we're currently on the `release_60` branch, but this may get upgraded in the near future! LLD is placed into rustc's sysroot in a `bin` directory. This is similar to where `gcc.exe` can be found on Windows. This directory is automatically added to `PATH` whenever rustc executes the linker, allowing us to define a `WasmLd` linker which implements the interface that `wasm-ld`, LLD's frontend, expects. Like Emscripten the LLD target is currently only enabled for Tier 1 platforms, notably OSX/Windows/Linux, and will need to be installed manually for compiling to wasm on other platforms. LLD is by default turned off in rustbuild, and requires a `config.toml` option to be enabled to turn it on. Finally the unstable `#![wasm_import_memory]` attribute was also removed as LLD has a native option for controlling this.

As such, there is no need to separately configure them. x.py will ignore the configuration when they are passed on the command line anyway. 2018-02-09T18:12:32+00:00 Alex Crichton alex@alexcrichton.com 2018-02-09T18:12:32+00:00 urn:sha1:9c05babe25bd25db423c7f83c31de000ee4d4db7 Right now the `--build` option was accidentally omitted, so we're bootstraping from `x86_64` to `i686`. In addition to being slower (more compiles) that's not actually bootstrapping!
