+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.

-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.
-
-(cherry picked from commit 97c3608326d123f5462e3504409a3a069611c0fb)
