-Subject: [PATCH 08/23] Fix powerpc64 ELFv2 big-endian struct-passing ABI
-
-The requirements here are not "ELFv1" requirements, but big-endian
-requirements, as the extension or non-extension of the argument is
-necessary to put the argument in the correct half of the register.
-Parameter passing in the ELFv2 ABI needs these same transformations.
-Since this code makes no difference on little-endian machines, simplify
-it to use the same code path everywhere.

-Subject: [PATCH 13/23] Fix double_check tests on big-endian targets
-
-Since the enums get optimized down to 1 byte long, the bits
-set in the usize member don't align with the enums on big-endian
-machines. Avoid this issue by shrinking the integer member to the
-same size as the enums.

-Subject: [PATCH 15/23] test/linkage-visibility: Ensure symbols are visible to
- dlsym
-
-DynamicLibrary uses libc's dlsym() function internally to find symbols.
-Some implementations of dlsym(), like musl's, only look at dynamically-
-exported symbols, as found in shared libraries. To also export symbols
-from the main executable, pass --export-dynamic to the linker.
