Use lld directly for Fuchsia target
Fuchsia already uses lld as the default linker, so there's no reason
to always invoke it through Clang, instead we can simply invoke lld
directly and pass the set of flags that matches Clang.

This commit adds opt-in support to the compiler to link to `jemalloc` in
the compiler. 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.
Closes #36963
|
|
This commit removes all jemalloc related submodules, configuration, etc,
from the bootstrap, from the standard library, and from the compiler.
This will be followed up with a change to use jemalloc specifically as
part of rustc on blessed platforms.

bootstrap: clean up a few clippy findings
remove useless format!()s
remove redundant field names in a few struct initializations
pass slice instead of a vector to a function
use is_empty() instead of comparisons to .len()
No functional change intended.

Fallback to the release number as we can't get the
git commit sha as we're not in a git repository.
Fixes #55341

In addition to to updating Cargo's submodule and Cargo's dependencies,
this also updates Cargo's build to build OpenSSL statically into Cargo
as well as libcurl unconditionally. This removes OpenSSL build logic
from the bootstrap code, and otherwise requests that even on OSX we
build curl statically.

If the rust-enabled lldb was built, then use it when running the
debuginfo tests. Updating the lldb submodule was necessary as this
needed a way to differentiate the rust-enabled lldb, so I added a line
to the --version output.
This adds compiletest commands to differentiate between the
rust-enabled and non-rust-enabled lldb, as is already done for gdb. A
new "rust-lldb" header directive is also added, but not used in this
patch; I plan to use it in #54004.
This updates all the tests.

This patch adds a few improvements to how the build system finds
LLVM's FileCheck program.
* On Fedora, the system LLVM installs FileCheck in the "llvm"
subdirectory of the LLVM libdir. This patch teaches the build
system to look there.
* This adds a configure option to specify which llvm-config executable
to use. This is handy on systems that can parallel install multiple
versions of LLVM; for example I can now:
./configure --llvm-config=/bin/llvm-config-5.0-64
... to build against LLVM 5, rather than whatever the default
llvm-config might be.
* Finally, this adds a configure- and config.toml- option to set the
path to FileCheck. This is handy when building against an LLVM
where FileCheck was not installed. This happens on compatibility
installs of LLVM on Fedora.

Clean up dependency tracking in Rustbuild [2/2]
Make `clear_if_dirty` calls in `Builder::cargo` with stamp dependencies for the given Mode.

This commit updates the debuginfo that is encoded in all of our released
artifacts by default. Currently it has paths like `/checkout/src/...` but these
are a little inconsistent and have changed over time. This commit instead
attempts to actually define the file paths in our debuginfo to be consistent
between releases.
All debuginfo paths are now intended to be `/rustc/$sha` where `$sha` is the git
sha of the released compiler. Sub-paths are all paths into the git repo at that
`$sha`.

add llvm-readobj to llvm-tools-preview
Similar to readelf but supports more object formats (it seems). Particularly useful to inspect in detail sections (e.g. their flags) and symbols (e.g. their types).

This optionally adds lldb (and clang, which it needs) to the build.
Because rust uses LLVM 7, and because clang 7 is not yet released, a
recent git master version of clang is used.
The lldb that is used includes the Rust plugin.
lldb is only built when asked for, or when doing a nightly build on
macOS. Only macOS is done for now due to difficulties with the Python
dependency.

This allows clearing it out and building it separately from the
compiler. Since it's essentially a different and separate crate this
makes sense to do, each cargo invocation should generally happen in its
own directory.

Provide llvm-strip in llvm-tools component
Shipping this tool gives people reliable way to reduce the generated executable size.
I'm not sure if this strip tool is available from the llvm version current rust is built on. But let's take a look. @japaric

Haiku: several smaller fixes to build and run rust on Haiku
This PR combines three small patches that help Rust build and run on the Haiku platform. These patches do not intend to impact other platforms.

This commit updates the stage0 build of tools to use the libraries of the stage0
compiler instead of the compiled libraries by the stage0 compiler. This should
enable us to avoid any stage0 hacks (like missing SIMD).

This commit expands on a previous commit to build llvm-tools as a rustup
component. It causes the llvm-tools component to be built if the
extended step is active. It also adds llvm-tools to the build manifest
so rustup can find it.

ship LLVM tools with the toolchain
this PR adds llvm-{nm,objcopy,objdump,size} to the rustc sysroot (right next to LLD)
this slightly increases the size of the rustc component. I measured these numbers on x86_64 Linux:
- rustc-1.27.0-dev-x86_64-unknown-linux-gnu.tar.gz 180M -> 193M (+7%)
- rustc-1.27.0-dev-x86_64-unknown-linux-gnu.tar.xz 129M -> 137M (+6%)

Previously, we didn't send --features to our cargo metadata invocations,
and thus missed some dependencies that we enable through the --features
mechanism.

This enables `./x.py test --stage 0 src/libstd --no-doc` and ensures the

Bump the bootstrap compiler to 1.26.0 beta
