Bug ID: 361405
Summary: disInstr(ppc): unhandled instruction: 0xFF81010C
Product: valgrind
Version: 3.11.0
Platform: Debian unstable
OS: other
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: ma...@debian.org
Seems like valgrind is missing support for PowerPC:
dis_fp_scr(ppc)(instr,mtfsfi)
disInstr(ppc): unhandled instruction: 0xFF81010C
primary 63(0x3F), secondary 268(0x10C)

==29681== Your program just tried to execute an instruction that Valgrind
==29681== did not recognise. There are two possible reasons for this.
==29681== 1. Your program has a bug and erroneously jumped to a non-code
==29681== location. If you are running Memcheck and you just saw a
==29681== warning about a bad jump, it's probably your program's fault.
==29681== 2. The instruction is legitimate but Valgrind doesn't handle it,
==29681== i.e. it's Valgrind's fault. If you think this is the case or
==29681== you are not sure, please let us know and we'll try to fix it.
==29681== Either way, Valgrind will now raise a SIGILL signal which will
==29681== probably kill your program.
