+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.
+

+
+Instead of not generating the function at all on big endian (which
+makes the CHECK lines fail), instead use to_le() on big endian,
+so that we essentially perform a bswap for both endiannesses.

+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.

-Subject: [PATCH] bootstrap: only show PGO warnings when verbose
-
-Building rustc with `--rust-profile-use` is currently dumping a lot of
-warnings of "no profile data available for function" from `rustc_smir`
-and `stable_mir`. These simply aren't exercised by the current profile-
-gathering steps, but that's to be expected for new or experimental
-functionality. I think for most people, these warnings will be just
-noise, so it makes sense to only have them in verbose builds.
