3  tool-selection option, with default in [ ]:
4    --tool=<name>             use the Valgrind tool named <name> [memcheck]
5
6  basic user options for all Valgrind tools, with defaults in [ ]:
7    -h --help                 show this message
8    --help-debug              show this message, plus debugging options
9    --version                 show version
10    -q --quiet                run silently; only print error msgs
11    -v --verbose              be more verbose -- show misc extra info
12    --trace-children=no|yes   Valgrind-ise child processes (follow execve)? [no]
13    --trace-children-skip=patt1,patt2,...    specifies a list of executables
14                              that --trace-children=yes should not trace into
15    --trace-children-skip-by-arg=patt1,patt2,...   same as --trace-children-skip=
16                              but check the argv[] entries for children, rather
17                              than the exe name, to make a follow/no-follow decision

54    --redzone-size=<number>   set minimum size of redzones added before/after
55                              heap blocks (in bytes). [not used by this tool]

82    --require-text-symbol=:sonamepattern:symbolpattern    abort run if the
83                              stated shared object doesn't have the stated
84                              text symbol.  Patterns can contain ? and *.
85    --soname-synonyms=syn1=pattern1,syn2=pattern2,... synonym soname
86              specify patterns for function wrapping or replacement.
87              To use a non-libc malloc library that is
88                  in the main exe:  --soname-synonyms=somalloc=NONE
