-Subject: [PATCH 02/10] mk: for stage0, use RUSTFLAGS to override target libs
- dir
-
-Setting HLIB specially for stage0 (and even more specially for windows)
-also affects the location we place TLIB. To keep the TLIBs we build in
-the place requested by configure, use '-L' and '--sysroot' to point
-stage0-rustc at the appropriate location.

-Subject: [PATCH 07/10] Allow overriding crate_hash with -C crate_hash
-
-The current crate hash is not stable from run-to-run.  This causes
-problems with bitbake; it needs a guarantee that every build with the
-same input will generate compatible output, otherwise sstate won't work.
-Using -C crate_hash, we can do that by using the bitbake input hash to
-determine the crate hash; the bitbake input hash will be stable, but
-still different for different rust recipes.
-
-Upstream-Status: not-appropriate
-
-Upstream wants to fix it's actual object generation here. See
-https://github.com/rust-lang/rust/issues/34902 (and others) for details.

Author	SHA1	Message	Date
Derek Straka	94280a636c	Merge pull request #171 from cardoe/pyro-1.20.0 (pyro) upgrade to 1.20.0	2017-10-10 12:06:43 -04:00
Derek Straka	4c764c3447	Always allow the clean-up to succeed Signed-off-by: Derek Straka <derek@asterius.io> (cherry picked from commit `34941a25e9`)	2017-10-10 08:48:31 -05:00
Johan Anderholm	980f6e2baf	rust: Don't specify allocator for >= 1.20.0 System allocator is the default in rust. (cherry picked from commit `37813c4dff`)	2017-10-03 21:51:03 -05:00
Johan Anderholm	633c18c655	libstd: correct path to COPYRIGHT (cherry picked from commit `2fd83daa46`)	2017-10-03 21:50:50 -05:00
Doug Goldstein	13e81c1961	bump to Rust 1.20.0 and Cargo 0.21 (cherry picked from commit `3bf7088579`)	2017-10-03 21:50:43 -05:00
Johan Anderholm	ee3fec561a	Switch to rustbuild Switch the build process to using Rust's new build system called rustbuild. At the same time stop using jemalloc on all platforms and switch to the system allocator since that was simplier to do. (cherry picked from commit `a4fe235317`)	2017-10-03 21:50:30 -05:00
Doug Goldstein	a086ab5c3d	cargo: convert to versioned include file We'll need the prior version of cargo to boot strap ourselves going forward so include the version info so we can support multiple versions in the tree. (cherry picked from commit `1ff41650d5`)	2017-10-03 21:50:21 -05:00
Doug Goldstein	f822a1e21f	update container to the pyro supported version (cherry picked from commit `1b8883be12`)	2017-10-03 21:49:56 -05:00
Doug Goldstein	c7d40b7e36	cargo{_common}.bbclass: abstract out parts for rustbuild rustbuild is a cargo based way to build Rust but all of our helper bits in cargo.bbclass would create a chicken/egg issue with dependencies since we pull down pre-built binaries and use those for boot strapping. (cherry picked from commit `e31d252eb0`)	2017-10-03 21:49:48 -05:00
Doug Goldstein	e4c106a186	cargo.bbclass: include CXXFLAGS for builds If g++ is invoked when building native bits with cargo we need to include CXXFLAGS. Signed-off-by: Doug Goldstein <cardoe@cardoe.com> (cherry picked from commit `0cccf8b25c`)	2017-10-03 21:49:39 -05:00
Doug Goldstein	f881c0897c	rustfmt: bump to 0.8.0 and use cargo-bitbake Switch to using cargo-bitbake to generate the recipe and bump versions at the same time. (cherry picked from commit `758f8459ec`)	2017-10-03 21:49:21 -05:00
Doug Goldstein	243bc13191	cargo: convert recipe to cargo-bitbake Generate the Cargo recipe with cargo-bitbake instead of having a handcrafted recipe. This should make future version bumps easier. Three known issues: - license checksum of the Apache license is a generateme value due to the license file having a difference name then what's in Cargo.toml. - branch= value was wrong for tags. Pointed to HEAD instead of the branch that the underlying tag commit came from. - Use https protocol when the repo is publicly accessible. (cherry picked from commit `398fecb48c`)	2017-10-03 21:49:11 -05:00
Doug Goldstein	5b7699b4f0	cargo.bbclass: improve debug note showing paths There was a bbnote that showed the path to the rustc and cargo binaries being used but this was not necessarily correct since it didn't use the exact variables used. (cherry picked from commit `c55fb403f8`)	2017-10-03 21:48:59 -05:00
Doug Goldstein	49c512c885	rust: drop custom target finding patch We shouldn't need to patch rustc to find the target but instead pass the full path to the target spec. This should solve #138. (cherry picked from commit `06a138a4a4`)	2017-10-03 21:48:45 -05:00
Johan Anderholm	b4527016df	cargo: build cargo using cargo and not make Instead of using the configure script paired with make, use Cargo to build Cargo. This moves us closer to being compatible with rustbuild. (cherry picked from commit `3e0f03d12a`)	2017-10-03 21:48:33 -05:00
Johan Anderholm	e04de10cfa	rust-common: provide C++ wrappers For similar reasons to the C and linker wrappers, using rustbuild requires a C++ wrapper to ensure that the right flags that Yocto needs are passed to the underlying compiler. (cherry picked from commit `e814ede9d9`)	2017-10-03 21:48:23 -05:00
Doug Goldstein	f6d973c5ca	compiler-rt: drop unused bits Since `a3fe7c75bf` this file has been unused and should have been deleted with that commit.	2017-06-21 11:51:15 -05:00

Doug Goldstein	a3fe7c75bf	drop Rust 1.12.1 and Cargo 0.13 In keeping with our supported versions release schedule at https://github.com/meta-rust/meta-rust/wiki this removes 1.12.1 from pyro.	2017-06-18 11:14:04 -05:00
