-Subject: [PATCH] Allow using external builds of the compiler-rt profile lib
-
-This changes the bootstrap config `target.*.profiler` from a plain bool
-to also allow a string, which will be used as a path to the pre-built
-profiling runtime for that target. Then `profiler_builtins/build.rs`
-reads that in a `LLVM_PROFILER_RT_LIB` environment variable.

-Subject: [PATCH] bootstrap: config: fix version comparison bug
-
-Rust requires a previous version of Rust to build, such as the current version, or the
-previous version.  However, the version comparison logic did not take patch releases
-into consideration when doing the version comparison for the current branch, e.g.
-Rust 1.71.1 could not be built by Rust 1.71.0 because it is neither an exact version
-match, or the previous version.
-
-Adjust the version comparison logic to tolerate mismatches in the patch version.
-
-Signed-off-by: Ariadne Conill <ariadne@dereferenced.org>

+Subject: [PATCH] compiletest: set the dylib path when gathering target cfg
+
+If the compiler is built with `rpath = false`, then it won't find its
+own libraries unless the library search path is set. We already do that
+while running the actual compiletests, but #100260 added another rustc
+command for getting the target cfg.
+
+    Check compiletest suite=codegen mode=codegen (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu)
+    thread 'main' panicked at 'error: failed to get cfg info from "[...]/build/x86_64-unknown-linux-gnu/stage1/bin/rustc"
+    --- stdout
+
+    --- stderr
+    [...]/build/x86_64-unknown-linux-gnu/stage1/bin/rustc: error while loading shared libraries: librustc_driver-a2a76dc626cd02d2.so: cannot open shared object file: No such file or directory
+    ', src/tools/compiletest/src/common.rs:476:13
+
+Now the library path is set here as well, so it works without rpath.
