Having it working is fairly essential for debugging. Inside src/utils/hsdis, After cloning binutils make; make demo; ./build/macosx-arm64/hsdis-demo Results in: Hello, world! ...And now for something completely different: Decoding from 0x1046e31a4 to 0x1046e3664...with decode_instructions_virtual hsdis: bad native mach=architecture not set in Makefile!; please port hsdis to this platform hsdis output options: I fixed it by changing the makefile to force the build flags: ARCH=aarch64 CFLAGS/aarch64 += -m64 Resulting in: Hello, world! ...And now for something completely different: Decoding from 0x10012719c to 0x10012765c...with decode_instructions_virtual Decoding for CPU 'aarch64' main: 0x10012719c sub sp, sp, #0x60 0x1001271a0 stp x29, x30, [sp, #80] ...etc Putting the library in the right place then made disassembly in java work for me. ------------- PR: https://git.openjdk.java.net/jdk/pull/2200
