The repository has no big-endian ARM ELF at all. These are a matched pair built from one object file, differing only in whether the linker was given --be8, so a test can tell the two layouts apart. Freestanding, 996 bytes each; the source and the build line are in tests_src/armeb.

There is no big-endian ARM ELF in the repository — I scanned all 823 and found zero
ELFDATA2MSBEM_ARMfiles, so nothing can currently test that path.These are a matched pair, built from the same object file and differing only in whether the linker was given
--be8:tests/armeb/be8_loophase_flags 0x05800400andtests/armeb/be32_loophas0x05000400. Having both matters more than having either, because the interesting property is the one bit that separates them, and a test that cannot compare against the other layout cannot show it is reading that bit rather than something else about the file.Freestanding, 996 bytes each, no libc and no imports. The source and the exact clang and
ld.lldinvocations are intests_src/armeb, so they rebuild anywhere clang runs.armebas a directory name follows the existingmips/mipselandppc/ppc64elsplit.Consumed by angr/cle's BE8 detection.
