1usage: valgrind [options] prog-and-args 2 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 18 --child-silent-after-fork=no|yes omit child output between fork & exec? [no] 19 --vgdb=no|yes|full activate gdbserver? [yes] 20 full is slower but provides precise watchpoint/step 21 --vgdb-error=<number> invoke gdbserver after <number> errors [999999999] 22 to get started quickly, use --vgdb-error=0 23 and follow the on-screen directions 24 --vgdb-stop-at=event1,event2,... invoke gdbserver for given events [none] 25 where event is one of startup exit valgrindabexit all none 26 --track-fds=no|yes track open file descriptors? [no] 27 --time-stamp=no|yes add timestamps to log messages? [no] 28 --log-fd=<number> log messages to file descriptor [2=stderr] 29 --log-file=<file> log messages to <file> 30 --log-socket=ipaddr:port log messages to socket ipaddr:port 31 32 user options for Valgrind tools that report errors: 33 --xml=yes emit error output in XML (some tools only) 34 --xml-fd=<number> XML output to file descriptor 35 --xml-file=<file> XML output to <file> 36 --xml-socket=ipaddr:port XML output to socket ipaddr:port 37 --xml-user-comment=STR copy STR verbatim into XML output 38 --demangle=no|yes automatically demangle C++ names? [yes] 39 --num-callers=<number> show <number> callers in stack traces [12] 40 --error-limit=no|yes stop showing new errors if too many? [yes] 41 --error-exitcode=<number> exit code to return if errors found [0=disable] 42 --show-below-main=no|yes continue stack traces below main() [no] 43 --suppressions=<filename> suppress errors described in <filename> 44 --gen-suppressions=no|yes|all print suppressions for errors? [no] 45 --db-attach=no|yes start debugger when errors detected? [no] 46 --db-command=<command> command to start debugger [... -nw %f %p] 47 --input-fd=<number> file descriptor for input [0=stdin] 48 --dsymutil=no|yes run dsymutil on Mac OS X when helpful? [no] 49 --max-stackframe=<number> assume stack switch for SP changes larger 50 than <number> bytes [2000000] 51 --main-stacksize=<number> set size of main thread's stack (in bytes) 52 [min(max(current 'ulimit' value,1MB),16MB)] 53 54 user options for Valgrind tools that replace malloc: 55 --alignment=<number> set minimum alignment of heap allocations [not used by this tool] 56 --redzone-size=<number> set minimum size of redzones added before/after 57 heap blocks (in bytes). [not used by this tool] 58 59 uncommon user options for all Valgrind tools: 60 --fullpath-after= (with nothing after the '=') 61 show full source paths in call stacks 62 --fullpath-after=string like --fullpath-after=, but only show the 63 part of the path after 'string'. Allows removal 64 of path prefixes. Use this flag multiple times 65 to specify a set of prefixes to remove. 66 --extra-debuginfo-path=path absolute path to search for additional 67 debug symbols, in addition to existing default 68 well known search paths. 69 --debuginfo-server=ipaddr:port also query this server 70 (valgrind-di-server) for debug symbols 71 --allow-mismatched-debuginfo=no|yes [no] 72 for the above two flags only, accept debuginfo 73 objects that don't "match" the main object 74 --smc-check=none|stack|all|all-non-file [stack] 75 checks for self-modifying code: none, only for 76 code found in stacks, for all code, or for all 77 code except that from file-backed mappings 78 --read-var-info=yes|no read debug info on stack and global variables 79 and use it to print better error messages in 80 tools that make use of it (Memcheck, Helgrind, 81 DRD) [no] 82 --vgdb-poll=<number> gdbserver poll max every <number> basic blocks [5000] 83 --vgdb-shadow-registers=no|yes let gdb see the shadow registers [no] 84 --vgdb-prefix=<prefix> prefix for vgdb FIFOs [/tmp/vgdb-pipe] 85 --run-libc-freeres=no|yes free up glibc memory at exit on Linux? [yes] 86 --sim-hints=hint1,hint2,... known hints: 87 lax-ioctls, enable-outer, fuse-compatible [none] 88 --fair-sched=no|yes|try schedule threads fairly on multicore systems [no] 89 --kernel-variant=variant1,variant2,... known variants: bproc [none] 90 handle non-standard kernel variants 91 --merge-recursive-frames=<number> merge frames between identical 92 program counters in max <number> frames) [0] 93 --num-transtab-sectors=<number> size of translated code cache [16] 94 more sectors may increase performance, but use more memory. 95 --aspace-minaddr=0xPP avoid mapping memory below 0xPP [guessed] 96 --show-emwarns=no|yes show warnings about emulation limits? [no] 97 --require-text-symbol=:sonamepattern:symbolpattern abort run if the 98 stated shared object doesn't have the stated 99 text symbol. Patterns can contain ? and *. 100 --soname-synonyms=syn1=pattern1,syn2=pattern2,... synonym soname 101 specify patterns for function wrapping or replacement. 102 To use a non-libc malloc library that is 103 in the main exe: --soname-synonyms=somalloc=NONE 104 in libxyzzy.so: --soname-synonyms=somalloc=libxyzzy.so 105 --sigill-diagnostics=yes|no warn about illegal instructions? [yes] 106 --unw-stack-scan-thresh=<number> Enable stack-scan unwind if fewer 107 than <number> good frames found [0, meaning "disabled"] 108 NOTE: stack scanning is only available on arm-linux. 109 --unw-stack-scan-frames=<number> Max number of frames that can be 110 recovered by stack scanning [5] 111 112 user options for Nulgrind: 113 (none) 114 115 Extra options read from ~/.valgrindrc, $VALGRIND_OPTS, ./.valgrindrc 116 117 Nulgrind is Copyright (C) 2002-2013, and GNU GPL'd, by Nicholas Nethercote. 118 Valgrind is Copyright (C) 2000-2013, and GNU GPL'd, by Julian Seward et al. 119 LibVEX is Copyright (C) 2004-2013, and GNU GPL'd, by OpenWorks LLP et al. 120 121 Bug reports, feedback, admiration, abuse, etc, to: www.valgrind.org. 122 123
