Five files for tri-pi cross-compilation and ARM64 Tor support:
- cmake/aarch64-toolchain.cmake: CMake toolchain file for aarch64-linux-gnu
- cmake/armhf-toolchain.cmake: same, for arm-linux-gnueabihf
- scripts/tri-pi-test.sh: QEMU-based test harness (user-mode + full-system)
for Pi 3B/3A+/4B/5. Runs the cross-compiled trianglesd under
qemu-aarch64-static so ARM binary correctness can be validated without
physical Pi hardware.
- src/tor/build-libtor-aarch64.sh: cross-compile libtor.a for aarch64
using the vendored configure flow from src/tor/configure.vendored.
These accompany the in-progress tri-pi bootstrap work (Hetzner Pi,
raspbian packaging).
Also staged (separately from the build scripts above):
- src/test/fuzz/transaction_deserialize_fuzz.cpp: libFuzzer harness for
CTransaction deserialization. Reads raw attacker-controlled bytes
into a CDataStream and calls Unserialize on a CTransaction, then
exercises hash determinism, round-trip serialize/parse, and
CheckTransaction bounds. Mirrors the Bitcoin Core deserialize-fuzz
pattern. Not yet wired into src/CMakeLists.txt — the BUILD_FUZZ=ON
gate currently only builds fuzz_script; a follow-up patch should add
the analogous stanza for this target.
