Subject: [PATCH 04/14] Require static native libraries when linking static
executables
-gcc/ld will create a dynamically-linked executable without warning, even
-when passed `-static`, when asked to link to a `.so`. Avoid this
-confusing and unintended behavior by always using the static version of
-libraries when trying to link static executables.
+On ELF targets like Linux, gcc/ld will create a dynamically-linked
+executable without warning, even when passed `-static`, when asked to
+link to a `.so`. Avoid this confusing and unintended behavior by always
+using the static version of libraries when trying to link static
+executables.
Fixes #54243

+Subject: [PATCH 08/14] Correct minimum system LLVM version in tests
+
+Since commit 9452a8dfa3ba, the new debug info format is only generated
+for LLVM 8 and newer versions. However, the tests still assume that LLVM
+7 will use the new debug info format. Fix the tests (and a comment in
+the code) to match the actual version check.

+Subject: [PATCH] round result of (highest as f64).log(2.0)
+
+Even though (1024f64).log(2.0) has an exact, representable, value, with
+rustc 1.32 on i386 it comes out as +9.999999999999999985 with
+optimization enabled. And the rustc doesn't like having two defintions
+for U1024 etc.
