Re: [Valgrind-users] Is there a Valgrind that knows arm64/aarch64?

Hmm, I'll check that. Right now the latest apt-update & upgrade seems to have broken my USB connection to the camera. I wanted to check a subroutine I wrote for a program that works with libghoto. I'm using: Linux version 4.16.0-2-arm64 (deb...@li...) (gcc version 7.3.0 (Debian 7.3.0-19)) #1 SMP Debian 4.16.12-1 (2018-05-27) The Valgrind was a 3.13.0 that I'd built from the distribution tarball, then I discovered the same version had been added (Debian Unstable) to the standard debs. I wanted to see Valkyrie so I did a make uninstall and installed Valgrind and Valkyrie from the debs. >From before it broke: ==6541== Memcheck, a memory error detector ==6541== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==6541== Using Valgrind-3.13.0 and LibVEX; rerun with -h for copyright info ==6541== Command: ./cmpi2 ==6541== ARM64 front end: branch_etc disInstr(arm64): unhandled instruction 0xD5380000 disInstr(arm64): 1101'0101 0011'1000 0000'0000 0000'0000 ==6541== valgrind: Unrecognised instruction at address 0x4014e2c. ==6541== at 0x4014E2C: init_cpu_features (cpu-features.c:72) ==6541== by 0x4014E2C: dl_platform_init (dl-machine.h:208) ==6541== by 0x4014E2C: _dl_sysdep_start (dl-sysdep.c:231) ==6541== by 0x40018D3: _dl_start_final (rtld.c:414) ==6541== by 0x4001B57: _dl_start (rtld.c:523) ==6541== by 0x40011C7: ???

Your program has a bug and erroneously jumped to a non-code ==6541== location. If you are running Memcheck and you just saw a ==6541== warning about a bad jump, it's probably your program's fault. ==6541== 2. The instruction is legitimate but Valgrind doesn't handle it, ==6541== i.e. it's Valgrind's fault. If you think this is the case or ==6541== you are not sure, please let us know and we'll try to fix it. ==6541== Either way, Valgrind will now raise a SIGILL signal which will ==6541== probably kill your program. ==6541== ==6541== Process terminating with default action of signal 4 (SIGILL): dumping core ==6541== Illegal opcode at address 0x4014E2C ==6541== at 0x4014E2C: init_cpu_features (cpu-features.c:72) ==6541== by 0x4014E2C: dl_platform_init (dl-machine.h:208) ==6541== by 0x4014E2C: _dl_sysdep_start (dl-sysdep.c:231) ==6541== by 0x40018D3: _dl_start_final (rtld.c:414) ==6541== by 0x4001B57: _dl_start (rtld.c:523) ==6541== by 0x40011C7: ???

(in /lib/aarch64-linux-gnu/ld-2.27.so) Note: see also the FAQ in the source distribution. It contains workarounds to several common problems. In particular, if Valgrind aborted or crashed after identifying problems in your program, there's a good chance that fixing those problems will prevent Valgrind aborting or crashing, especially if it happened in m_mallocfree.c. If that doesn't help, please report this bug to: www.valgrind.org In the bug report, send all the above text, the valgrind version, and what OS and version you are using. Thanks.
