When i run valgrind with i this error:
vex amd64->IR: unhandled instruction bytes: 0x62 0xF2 0xFD 0x48 0x59 0x44 0x24
0x1 0x49 0x89
vex amd64->IR: REX=0 REX.W=0 REX.R=0 REX.X=0 REX.B=0
vex amd64->IR: VEX=0 VEX.L=0 VEX.nVVVV=0x0 ESC=NONE
vex amd64->IR: PFX.66=0 PFX.F2=0 PFX.F3=0
==26057== valgrind: Unrecognised instruction at address 0x42f977.
the related code at 0x42f977 is:
...
42f972: 4c 01 f8 add %r15,%rax
42f975: ff d0 call *%rax
42f977: 62 f2 fd 48 59 44 24 vpbroadcastq 0x8(%rsp),%zmm0
42f97e: 01
42f97f: 49 89 44 24 38 mov %rax,0x38(%r12)
...
it is avx related code probably 512.. the version i encountered is 3.24.0
however i also build from git with head 19b70d65 (3.25.git). problem still
there.
i attached my configure log of
./configure --enable-inner --disable-ubsan --enable-lto --enable-tls
--prefix=/home/kazim/.local/valgrind
