Heyho,
when running valgrind on an application linking to libgcrypt, I get the
following error:
vex amd64->IR: unhandled instruction bytes: 0x48 0xF 0xC7 0xF0 0x72 0x4 0xFF

I have a x86_64 gentoo system with valgrind-3.11.0 and libgcrypt-1.7.3
installed.
The CFLAGS from my make.conf are:
CFLAGS="-O2 -pipe"
CFLAGS="${CFLAGS} -march=core-avx2 -mtune=core-avx2 -mcx16 -msahf -mmovbe -maes"
CFLAGS="${CFLAGS} -mpclmul -mpopcnt -mabm -mno-lwp -mfma -mno-fma4 -mno-xop"
CFLAGS="${CFLAGS} -mbmi -mbmi2 -mno-tbm -mavx -mavx2 -msse4.2 -msse4.1 -mlzcnt"
CFLAGS="${CFLAGS} -mrdrnd -mf16c -mfsgsbase --param l1-cache-size=32"
CFLAGS="${CFLAGS} --param l1-cache-line-size=64 --param l2-cache-size=4096"
Please keep me in the CC in your replies, since I am no list member.
