UnicronNLandClaude Opus 5.5
4f042f7225
Interpreter + JIT for ARM, Thumb-2, VFPv4 and NEON, ARM EABI syscall translation, signals, threads and self-modifying code. Runs static bionic programs on the Frame. Tests: A64 encoders vs llvm-mc, a differential instruction fuzzer and program tests against qemu-arm. Not shipped; the README lists the steps towards running 32-bit-only APKs.
