-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] Disable jump threading of float equality
+
+Jump threading stores values as `u128` (`ScalarInt`) and does its
+comparisons for equality as integer comparisons.
+This works great for integers. Sadly, not everything is an integer.
+
+Floats famously have wonky equality semantcs, with `NaN!=NaN` and
+`0.0 == -0.0`. This does not match our beautiful integer bitpattern
+equality and therefore causes things to go horribly wrong.
+
+While jump threading could be extended to support floats by remembering
+that they're floats in the value state and handling them properly,
+it's signficantly easier to just disable it for now.
+

+Subject: [PATCH] Use an explicit x86-64 cpu in tests that are sensitive to it
+
+There are a few tests that depend on some target features **not** being
+enabled by default, and usually they are correct with the default x86-64
+target CPU. However, in downstream builds we have modified the default
+to fit our distros -- `x86-64-v2` in RHEL 9 and `x86-64-v3` in RHEL 10
+-- and the latter especially trips tests that expect not to have AVX.
+
+These cases are few enough that we can just set them back explicitly.
