-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.
-
-(cherry picked from commit eca0a7e72346ba123ace318a0f9c28c57d990aeb)

-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.
