* classes: Update classes to match new bitbake class scope functionalityRichard Purdie2022-08-121-177/+0
| | | | | | | | | Move classes to classes-global or classes-recipe as appropriate to take advantage of new bitbake functionality to check class scope/usage. (From OE-Core rev: f5c128008365e141082c129417eb72d2751e8045) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* classes: Add SPDX license identifiersRichard Purdie2022-08-121-0/+2
| | | | | | | | | | | | As stated in our top level license files, the license is MIT unless otherwise stated. Add SPDX identifers accordingly. Replace older license statementa with the standardised syntax. Also drop "All Rights Reserved" expression as it isn't used now, doesn't mean anything and is confusing.

* rust-common: Simplify libc handlingRichard Purdie2022-08-081-37/+8
| | | | | | | | | | The current libc handling code is simply wrong in many cases. Simplify it to a check of the triplet for musl handling which is much simpler and less error prone when handling things like nativesdk targets.

* rust: Introduce RUST_BUILD_ARCHAndrew Jeffery2022-03-021-0/+4
| | | | | | | | | | | | | RUST_BUILD_ARCH contains the arch_to_rust_arch()-translated value of BUILD_ARCH. This is necessary to acquire the correct snapshot artifacts under Linux where `uname -m` reports "ppc64le" rather than "powerpc64le".

* rust: Introduce arch_to_rust_arch()Andrew Jeffery2022-03-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On modern Power systems `uname -m` yields 'ppc64le' while the toolchain knows the architecture as 'powerpc64le'. Provide a mapping from one to the other to integrate with the existing architecture configuration flags. arch_to_rust_arch() only exists to map the OE *_ARCH variables before any further processing, unlike arch_to_rust_target_arch() which is specific to the internal triple handling of rust. On Linux ppc64le systems the changes give the following config: ``` $ cat ./tmp/work/ppc64le-linux/rust-native/1.58.0-r0/targets/ppc64le-linux.json { "llvm-target": "powerpc64le-unknown-linux-gnu", "data-layout": "e-m:e-i64:64-n32:64-v256:256:256-v512:512:512", "max-atomic-width": 64, "target-pointer-width": "64", "target-c-int-width": "64", "target-endian": "little", "arch": "powerpc64", "os": "linux", "env": "gnu", "vendor": "unknown", "target-family": "unix", "linker": "gcc", "cpu": "generic", "dynamic-linking": true, "executables": true, "linker-is-gnu": true, "linker-flavor": "gcc", "has-rpath": true, "has-elf-tls": true, "position-independent-executables": true, "panic-strategy": "unwind" } ``` Change-Id: Ief0c01189185d7d4da31d307270bec4e1de674ca (From OE-Core rev: 9ab61e3cfef0157393cb870d606c2f362e190889) Signed-off-by: Andrew Jeffery <andrew@aj.id.au> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* rust-common.bbclass: rewrite toolchain wrappers in (native) pythonAlexander Kanavin2021-10-141-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | librsvg on centos 7 and friends exhibits the same libtinfo leakage problem, this time coming from the compiler and not the linker. Simply covering the compiler by the existing C wrapper-of-wrapper does not work, as rust-native builds put Important Stuff into LD_LIBRARY_PATH and unsetting it breaks things badly. Rather than try to figure out which combination of wrappers and LD_LIBRARY_PATH settings works for which situation, or provide some kind of sh-native, let's simply use python3-native for the wrappers, which should insulate builds from the the host shell. rust-native already depends on python3-native, so this does not lengthen the builds. This also reverts: rust-common: Hack around LD_LIBRARY_PATH issues on centos7 (commit 63b1fd2226b5f146d6c853cc57417704df378438). I'd also like to say boo to Red Hat (or GNU?) for breaking ABI compatibility for stat() in glibc 2.33, we ended up sorting this mess because of it.

* rust-common: Hack around LD_LIBRARY_PATH issues on centos7Richard Purdie2021-09-021-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building cargo-native on centos7 with buildtools tarball installed, we see failures: /bin/sh: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by /home/pokybuild/yocto-worker/reproducible-centos/build/build-st/tmp/work/x86_64-linux/cargo-native/1.54.0-r0/recipe-sysroot-native/usr/lib/libtinfo.so.5) We also see this for libstd-rs once cargo-native is fixed. The reason for this is that the wrapper script cargo-native/1.54.0-r0/wrapper/target-rust-ccld has /bin/sh as it's interpreter and cargo calls this with LD_LIBRARY_PATH set to include the recipe-sysroot-native. The host /bin/sh links to libtinfo from the host but it finds the version in the sysroot which needs a newer libc. This results in the above error since the loader is an older libc and the two are incompatible. Our ccld wrapper calls gcc/ld which don't need the LD_LIBRARY_PATH variable set. We can't patch this out the source since we're using a prebuilt binary to generate a new cargo binary so this is impossible to bootstrap. Instead, put a binary wrapper into place which removes LD_LIBRARY_PATH from the environment before calling the original wrapper (left in shell as it is simpler to maintain).

* rust-cross*: Fix OVERRRIDE references in task signature computationRichard Purdie2021-08-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The oeqa selftest test: sstatetests.SStateTests.test_sstate_sametune_samesigs which checks if the sstate checksums of two identical machines (using the same tune) are the same, apart from changes within the machine specific stamps directory, fails on the assertion: self.assertCountEqual(files1, files2) due to the signature of various 32 bit package builds such as: x86_64-linux/lib32-rust-cross-i686 x86_64-linux/rust-cross-i686 x86-pokymllib32-linux/lib32-libstd-rs x86-pokymllib32-linux/lib32-rust differing. Jumping down the rabbit hole past all the bitbake-diffsig outputs that differ due to dependent hashes, you come to a diff of: -Variable MACHINEOVERRIDES value is ${@bb.utils.contains('TUNE_FEATURES', 'mx32', 'x86-x32:', '', d)}${@bb.utils.contains('TUNE_FEATURES', 'm32', 'x86:', '', d)}qemuall:${MACHINE} +Variable MACHINEOVERRIDES value is ${@bb.utils.contains('TUNE_FEATURES', 'mx32', 'x86-x32:', '', d)}${@bb.utils.contains('TUNE_FEATURES', 'm32', 'x86:', '', d)}qemuall:${MACHINE}:qemux86 in stamps/x86_64-linux/rust-cross-i686/1.54.0-r0.do_rust_gen_target.<sig> This is because there are two rust functions referencing OVERRIDES related variables (target_is_armv7 and llvm_features_from_tune).
