From: Sunil Dora <sunilkumar.dora@windriver.com>
This patch trims the source directory at the string "rustc" before cc
hashes it into the object file names. After the shared source rework the
build no longer runs under rustc-*-src, so the sources that
compiler-builtins generates into OUT_DIR are not trimmed and the build
path ends up in their names.
Replaced by cc-hash-object-names-relative-to-source-roots.patch.

-rust: reproducibility issue fix with v1.84
-
-A few crates are using the updated version of the 'cc' crate and this is causing the generated object file names containing a unique hashmap id.
-By the following changes same hash values will be genarted even for diffrent build paths.
-
-Below are the links for detailed bug description & discusssion with upstream rust.

compiler-builtins compiles two sets of sources with cc: the
outline-atomics files it generates into OUT_DIR and the compiler-rt
intrinsics it reads from RUST_COMPILER_RT_ROOT. cc hashes the absolute
source directory into each object file name, so the names change with
the build location.
The added patch strips OUT_DIR or RUST_COMPILER_RT_ROOT before hashing,
falling back to CARGO_MANIFEST_DIR. It replaces
repro-issue-fix-with-cc-crate-hashmap.patch and covers both sets of
sources.

v2: Upstream-Status of the added patch is now Backport (cc-rs merged
the OUT_DIR half); its header wording updated to match. No code
change to the rust sources.

+Subject: [PATCH] cc: hash object names relative to the root the source came
+ from
+
+compiler-builtins builds two sets of objects with the cc crate: the
+outline-atomics sources (lse_*.S) it generates into OUT_DIR, and the
+compiler-rt C intrinsics it reads from RUST_COMPILER_RT_ROOT. cc hashes the
+absolute source directory into each object file name, so the names change
+with the build location and the shipped rlib is not reproducible.
+
+Strip OUT_DIR or RUST_COMPILER_RT_ROOT before hashing, falling back to
+CARGO_MANIFEST_DIR as upstream already did.
+
+The OUT_DIR part is generic and is merged upstream as rust-lang/cc-rs
+commit fe27e7b6262, in a slightly different shape: the upstream tree
+moved on from the cc 1.2.0 that rust vendors, so the change here keeps
+the form that fits these sources. RUST_COMPILER_RT_ROOT is set by
+rust's own build system, so that part stays local to this patch.
+
+Upstream-Status: Backport [https://github.com/rust-lang/cc-rs/commit/fe27e7b62629daddccf1bdc9e9a447a37de2cd06]

cargo hashes the "host:" line of "rustc -vV" into the metadata of build
scripts and proc-macros. Every target crate that depends on one picks it
up, so the same crate gets a different -C metadata and StableCrateId on
an x86_64 and an aarch64 build host. The added patch drops the host line
from that hash.

+Subject: [PATCH] rust: keep the build host triple out of cargo unit metadata
+
+cargo hashes the "host:" line of "rustc -vV" into the metadata of host
+units, that is build scripts and proc-macros. Every target crate that
+depends on one picks that up through its own metadata, so the same crate
+gets a different -C metadata and StableCrateId on an x86_64 and an aarch64
+build host. Drop the host from the hash. The same class of problem is
+reported upstream, framed as OS differences, in
+https://github.com/rust-lang/cargo/issues/8140.
+
+Patch by Alejandro Enedino Hernandez Samaniego, from his strict-version-hash
+v5 series for openembedded-core:

Backport of rust-lang/rust commit f9d9939 [1] by jprochazk and mejrs.
DocLinkResMap was an UnordMap, so its iteration order varied with the
build host and that order reached the encoded rmeta. An FxIndexMap keeps
it stable. The commit is in rust 1.99, so this only carries it until the
next rust upgrade.

+DocLinkResMap was an UnordMap, so its iteration order varied with the build
+host and that order ended up in the encoded rmeta. An FxIndexMap keeps the
+serialisation stable. Only the code change is carried here, not the

HygieneEncodeContext::encode walks a hash set while it writes the syntax
context and expansion records into the rmeta, so the byte order of the
records follows the iteration order of the set and differs between
builds on the arm workers. The added patch sorts both sets before they
are written.
Upstream tracks this as rust-lang/rust issue 129094 [1] and has fixed
it differently in pull request 161450 [2], merged after 1.99 branched.
That change is too big to backport to 1.98 safely, so carry this small
sort until a rust upgrade contains it.

v2: added Alejandro's Signed-off-by, dropped the link paragraph;
upstream references now footnote links (PR 161450 merged meanwhile,
noted why it is not backported here). No code change.

+Subject: [PATCH] rust: sort syntax contexts and expansions before encoding
+
+HygieneEncodeContext encodes the pending syntax contexts and expansions in
+hash-map order, so the encoded rmeta depends on the build host. Sort both
+before encoding. Upstream has fixed the same problem with a different
+approach in https://github.com/rust-lang/rust/pull/161450, merged after
+rust 1.99 branched, so this stays a local fix rather than a backport
+until a rust upgrade contains it.
