Redid how compiler-rt is built by using the Rust makefiles to build it
instead of compiler-rt's build system. Rust itself deviated from using
compiler-rt's build system and provided their own rules requiring the
source tree to be configured to use them.
We need the Rust snapshot (stage0) for the build environment not the
host environment. This is not affecting us currently because we are only
building native versions of this today but should improve the behavior
of #81 or if any Rust components are built for the target machine.
Since we no longer use shared source we can modify the source directory
as we build. This drops another patch we need to build and simplifies
the addition of Rust 1.12.1 in #97.
I'm honestly not sure what this patch does since everything appears to
build the same with and without it. I did a `tree` of the sysroots and
images and I don't see any file differences. Something like this used to
be necessary in Gentoo but I dropped it a few releases back.
The host system where things are being built really should control what
toolchain is used for stage0. This in theory should improve #23 but I'm
not sure how to specify a hash per host sys.
This drops the ability to supply your own rust through the PACKAGECONFIG
local-rust option. This isn't tested and we really need to better expand
support for build arches. At the same time this simplifies how the rust
stage0 snapshot is extracted and used by the build system.
Pin the versions of different Rust component packages to the same
version to ensure smooth upgrades. Not sure how to hook the compiler
together with the shared library. Likely rust-cross will need to provide
some kind of dependency to make this happen.
Avoid issues with non-native builds by splitting up the packages a
little closer to how they should be while still leaving the main package
containing everything Rust uses. This makes it possible to build
rust-llvm for the target, hopefully improving issue #81.
Future versions of LLVM require cmake to build so it will be easier to
prove that out on a known good build and to allow future versions to use
this as common code.
This whitespace in here causes rust to not be happy with the features
and throw warnings about a feature such as ' +sse3' being unsupported
when '+sse3' works just fine. Amazingly will cause rustc to abort when
you try to resolve the features to valid configs with the `--print` arg
to rustc.
The data layout changed for Rust 1.10. I noticed this because I got a
crash when using rust-native to build rust. The assertion that hit was
saying data layout mismatch and caused me to check the values in the
Rust sources.
Convert libstd-rs to not use the shared source setup and instead use
its own extracted directory. Include the version info in the bitbake
file so that in the future we can support multiple versions via a
PREFERRED_VERSIONS variable.

rustllvm ships some c++ code that we need to ensure is built with the
flags we want. Abuse an existing variable to make this happen.
This should fix our issues with the libstdc++ cxx11 abi (_GLIBCXX_USE_CXX11_ABI).
When rust's build system builds llvm itself, it uses these flags. Avoid
them interfering with other things by cleaning their usage out of the
platform cfg mk file.
The old cargo.bbclass had no users in meta-rust and had lots of
problems (not least of which was lots of duplicated lines with
cargo_util.bbclass). Delete the old cargo.bbclass and replace it
entirely wiht cargo_util
OE-Core rev aeb653861a0ec39ea7a014c0622980edcbf653fa (between jethro and
krogoth) removed -e from the default flags in EXTRA_OEMAKE. Without
this, the makefile will default to gcc for CC.
Instead of building a full compiler, we can use rust-native to
cross-compile. All we need is a cross-compiled standard library, which
libstd-rs builds, and a compiler spec file. rust-cross is now just used
to generate the json spec file for cross-compiling, which is naturally
much faster.
Rust does something fairly different than in 1.7. Instead of just
expecting the tarball to exist, it either expects an already extracted
and ready toolchain, or else it does everything itself.
To work with that, we'll always pass --use-local-rust to ./configure so
that bootstrap.py doesn't try to download anything. We'll either
download and setup a snapshot ourselves, or use the system rust, based
on PACKAGECONFIG[local-rust] as before
