You forgot to say which version of valgrind (run "valgrind --version")
and which version of hardware (on Linux: "cat /proc/cpuinfo").
Assembling that unhandled Thumb-mode instruction 0xEEBA 0x7BEF:
----- foo.S
.thumb_func
abc:
.short 0xEEBA, 0x7BEF
-----
$ gcc -c foo.S
$ gdb foo.o
(gdb) x/i 1
0x1 <abc+1>: vcvt.f64.s32 d7, d7, #1
(gdb) x/x 0
0x0 <abc>: 0x7befeeba
-----
So does your hardware have vector floating point to execute 'vcvt.f64.s32' ?
The software believes (or was told) that the hardware does. Is it true?
Check the configuration steps. Look for a file "config.h", and see if
its contents describe your setup accurately.
