Hopefully these fix reproducibility issue when built from different hosts. Unfortunately these go in a bit of a different way than my next version, so I will wait for the result before sending to avoid confusion, but I'm fine with these if they work, lets just add my sign off to the actual patches based off of mine instead of the "Patch from Alejandro + OE link". Thanks Alejandro. Your series did the hard part here, finding where the host details get into the rust builds in the first place. Mine builds on that map. On the contrib branch run the arm reproducible builders came back with the rust family gone from the failing list, so it looks good so far. The real confirmation will be the autobuilder runs on master-next once the series gets picked up there. On the sign-off: your Signed-off-by is already inside the two carried patch files, but you are right that it is not in the commit messages, so git log only shows mine. In v2 I will add your Signed-off-by to those two commit messages and drop the "Patch from + link" wording, together with whatever else the review brings up.

This series fixes that. rust: drop the cc object-name reproducibility patch rust: hash cc object names relative to their source roots The patch we carried trimmed the build path by matching the string "rustc", and the shared-source rework broke that for one of the two sets of sources cc compiles. The replacement strips the roots the sources actually come from.

The RUST_COMPILER_RT_ROOT part is specific to rust's own build system, so it is not part of that pull request. rust: keep the build host triple out of cargo unit metadata From Alejandro Enedino Hernandez Samaniego's strict-version-hash series, carried with his sign-off: https://lists.openembedded.org/g/openembedded-core/topic/120939810<https://urldefense.com/v3/__https://lists.openembedded.org/g/openembedded-core/topic/120939810__;!!AjveYdw8EvQ!bAZjXNFQVd7FZGNUYCD78uEwFODIFOwfzeAgrtyk8STWe6WGkL_Vzz465VBcVThqLu12-qJFkYBIO_U1bW7uALNnJw$> cargo mixes the "host:" line of "rustc -vV" into build script and proc-macro metadata, and target crates inherit it.

It is in rust 1.99, so this drops out at the next rust upgrade. rust: sort hygiene data before it is encoded Also from Alejandro's series. Upstream is fixing the same problem with a different approach in https://github.com/rust-lang/rust/pull/161450<https://urldefense.com/v3/__https://github.com/rust-lang/rust/pull/161450__;!!AjveYdw8EvQ!bAZjXNFQVd7FZGNUYCD78uEwFODIFOwfzeAgrtyk8STWe6WGkL_Vzz465VBcVThqLu12-qJFkYBIO_U1bW5_rpjPaQ$>, which is still open. Alejandro's StableCrateId patch is not included: the value it pins is already host-independent in our builds, and it broke three rust test suite cases when the autobuilder tested it. Tested on the autobuilder: the x86 reproducible builder green with zero differing packages, the rust test suite green, and on both arm builders rust, rust-dbg, rust-rustdoc and libstd-rs-dev gone from the failing list.
