Hi,
I got this message from valgrind:
dis_cache_manage(ppc)(opc1|b21to25|b0)
disInstr(ppc): unhandled instruction: 0x7C2907EC
primary 31(0x1F), secondary 2028(0x7EC)
==714== valgrind: Unrecognised instruction at address 0x10d410e0.
==714== Your program just tried to execute an instruction that Valgrind
==714== did not recognise. There are two possible reasons for this.
==714== 1. Your program has a bug and erroneously jumped to a non-code
==714== location. If you are running Memcheck and you just saw a
==714== warning about a bad jump, it's probably your program's fault.
==714== 2. The instruction is legitimate but Valgrind doesn't handle it,
==714== i.e. it's Valgrind's fault. If you think this is the case or
==714== you are not sure, please let us know and we'll try to fix it.
==714== Either way, Valgrind will now raise a SIGILL signal which will
==714== probably kill your program.
==714==
==714== Process terminating with default action of signal 4 (SIGILL):
dumping core
==714== Illegal opcode at address 0x10D410E0
==714== at 0x10D410E0: dsputil_init_ppc (dsputil_ppc.c:222)
==714== by 0x10CF5053: dsputil_init (dsputil.c:4693)
==714== by 0x10CD306F: aac_decode_init (aac.c:472)
==714== by 0x10CCEAAB: avcodec_open (utils.c:484)
==714== by 0x10CB311F: av_find_stream_info (utils.c:1887)
This is FFMpeg code running on a PPC.
It seems like problem has been seen before:
http://www.mail-archive.com/gn...@gnu.org/msg01640.html
I am using valgrind/VEX from Trunk, and I believe that it is these
revisions:
Valgrind revision 11029
VEX revision 1959
Does anybody know if this instruction is valid? And how to add this to
VEX, if it is missing?
