Errr, did you read the output? "valgrind --help-debug /bin/date"

Vex options for all Valgrind tools:
--vex-iropt-verbosity=<0..9> [0]
--vex-iropt-level=<0..2> [2]
--vex-iropt-register-updates=unwindregs-at-mem-access
|allregs-at-mem-access
|allregs-at-each-insn
[unwindregs-at-mem-access]
--vex-iropt-unroll-thresh=<0..400> [120]
--vex-guest-max-insns=<1..100> [50]
--vex-guest-chase-thresh=<0..99> [10]
--vex-guest-chase-cond=no|yes [no]
--trace-flags and --profile-flags values (omit the middle space):
1000 0000 show conversion into IR <<<<< RIGHT HERE (etc.)
0100 0000 show after initial opt
0010 0000 show after instrumentation
0001 0000 show after second opt
0000 1000 show after tree building
0000 0100 show selecting insns
0000 0010 show after reg-alloc
0000 0001 show final assembly
(Nb: you need --trace-notbelow and/or --trace-notabove with --trace-flags
for full details)
debugging options for Valgrind tools that report errors
--dump-error=<number> show translation for basic block associated
with <number>'th error context [0=show none]
