Hi,
I'm running valgrind-3.2.3 and I get the following error:
vex amd64->IR: unhandled instruction bytes: 0x66 0xF 0xF7 0xC1
==1314== valgrind: Unrecognised instruction at address 0x569AC45.
and it then instructs me to let you guys know. Outside of valgrind my
program seems to run fine.
My c++ code was compiled with both gcc 4.1.2 and icc in debug mode (-O0
-g3) and they both give the same result. uname -a says: Linux hex
2.6.18.8-0.3-default #1 SMP Tue
Apr 17 08:42:35 UTC 2007 x86_64 x86_64 x86_64 GNU/Linux and my cpus
are: Dual-Core AMD Opteron(tm) Processor 8222 SE
My code makes heavy use of SSE/SSE2 instructions and my guess is that
one of those SSE instructions isn't supported by valgrind.
Unfortunately, I don't know how to find out which instruction that is.
Let me know if you need any more info.

> vex amd64->IR: unhandled instruction bytes: 0x66 0xF 0xF7 0xC1 Yuk. That's maskmovdqu, which is pretty horrible. =46rom a quick scan of the sources, it is at least supported in 32-bit mode but not yet in 64-bit mode. I suggest you file a bug report at=20 http://valgrind.org/support/bug_reports.html, or possibly reopen bug #137714 (see http://bugs.kde.org/show_bug.cgi?id=3D137714) J > =3D=3D1314=3D=3D valgrind: Unrecognised instruction at address 0x569AC45. > > and it then instructs me to let you guys know.
