-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)

-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.
+
