rustc: Don't export builtins/panic/alloc syms

2017-01-27T07:47:39+00:00

This hides symbols from various unstable and implementation-detail crates of the standard library. Although typically transitive exported `pub extern` functions are exported from cdylibs, these crates aren't necessary as they're all implementation details. Closes #34493

Auto merge of #38679 - alexcrichton:always-deny-warnings, r=nrc

2017-01-08T08:22:06+00:00

Remove not(stage0) from deny(warnings) Historically this was done to accommodate bugs in lints, but there hasn't been a bug in a lint since this feature was added which the warnings affected. Let's completely purge warnings from all our stages by denying warnings in all stages. This will also assist in tracking down `stage0` code to be removed whenever we're updating the bootstrap compiler.

Build a dummy alloc_jemalloc crate on platforms that don't support it

2016-09-30T21:03:00+00:00

This is a hack to support building targets that don't support jemalloc alongside hosts that do. The jemalloc build is controlled by a feature of the std crate, and if that feature changes between targets, it invalidates the fingerprint of std's build script (this is a cargo bug); so we must ensure that the feature set used by std is the same across all targets, which means we have to build the alloc_jemalloc crate for targets like emscripten, even if we don't use it.

Add s390x support

2016-09-09T21:28:19+00:00

This adds support for building the Rust compiler and standard library for s390x-linux, allowing a full cross-bootstrap sequence to complete. This includes: - Makefile/configure changes to allow native s390x builds - Full Rust compiler support for the s390x C ABI (only the non-vector ABI is supported at this point) - Port of the standard library to s390x - Update the liblibc submodule to a version including s390x support - Testsuite fixes to allow clean "make check" on s390x Caveats: - Resets base cpu to "z10" to bring support in sync with the default behaviour of other compilers on the platforms. (Usually, upstream supports all older processors; a distribution build may then chose to require a more recent base version.) (Also, using zEC12 causes failures in the valgrind tests since valgrind doesn't fully support this CPU yet.) - z13 vector ABI is not yet supported. To ensure compatible code generation, the -vector feature is passed to LLVM. Note that this means that even when compiling for z13, no vector instructions will be used. In the future, support for the vector ABI should be added (this will require common code support for different ABIs that need different data_layout strings on the same platform). - Two test cases are (temporarily) ignored on s390x to allow passing the test suite. The underlying issues still need to be fixed: * debuginfo/simd.rs fails because of incorrect debug information. This seems to be a LLVM bug (also seen with C code). * run-pass/union/union-basic.rs simply seems to be incorrect for all big-endian platforms. Signed-off-by: Ulrich Weigand

Fix alloc_jemalloc on windows gnu targets

2016-05-01T12:16:06+00:00

jemalloc prefixes the symbols by default on Windows so we need to account for that to avoid link errors such as: `undefined reference to `mallocx'` when using alloc_jemalloc.

Prefix jemalloc on DragonFly to prevent segfaults.
