+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] Improve generating Custom entry function
-
-This commit is aimed at making compiler generated entry functions
-(Basically just C `main` right now) more generic so other targets can do
-similar things for custom entry. This was initially implemented as part
-of https://github.com/rust-lang/rust/pull/100316.
-
-Currently, this moves the entry function name and Call convention to the
-target spec.

-
-On wasm, the age-old C trick of having a main function which can either have
-no arguments or argc+argv doesn't work, because wasm requires caller and
-callee signatures to match. WASI's current strategy is to have compilers
-mangle main's name to indicate which signature they're using. Rust uses the
-no-argument form, which should be mangled as `__main_void`.
-
-This is needed on wasm32-wasi as of #105395.

+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.

-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.
