Bug ID: 381514
Summary: unhandled instruction 0xD53BE002
Product: valgrind
Version: 3.12.0
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: memcheck
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
I have an aarch64 Linux application that has the following instruction in its
code:
7d48c: d53be002 mrs x2, cntfrq_el0
That causes valgrind to abort execution with
ARM64 front end: branch_etc
disInstr(arm64): unhandled instruction 0xD53BE002
disInstr(arm64): 1101'0101 0011'1011 1110'0000 0000'0010
==2561== valgrind: Unrecognised instruction at address 0x48eb48c.
==2561== at 0x48EB48C: xlnkGetGlobalCounter (in
/media/card/libfilter2d_optflow.so)
==2561== Your program just tried to execute an instruction that Valgrind
==2561== did not recognise. There are two possible reasons for this.
==2561== 1. Your program has a bug and erroneously jumped to a non-code
==2561== location. If you are running Memcheck and you just saw a
==2561== warning about a bad jump, it's probably your program's fault.
==2561== 2. The instruction is legitimate but Valgrind doesn't handle it,
==2561== i.e. it's Valgrind's fault. If you think this is the case or
==2561== you are not sure, please let us know and we'll try to fix it.
==2561== Either way, Valgrind will now raise a SIGILL signal which will
==2561== probably kill your program.
==2561==
==2561== Process terminating with default action of signal 4 (SIGILL)
==2561== Illegal opcode at address 0x48EB48C
==2561== at 0x48EB48C: xlnkGetGlobalCounter (in
/media/card/libfilter2d_optflow.so)
