Which flags does --trace incorporate? Or in otherwords, where is the printfs coming from: I don't see trace as an option on the d8 help list, but it does work:
I see the function name "test" being printed out: (e.g.) 1: ~+51(this=0x24e1a20144b9 <JS Global Object>) { and the output of the function and its type as well: <String[2]: aa> My goal in with this is to determine the number of times a function for a given set of arguments is called, and so if I can see where these traces are being printed, I can maintain my own data structure in the same location. program: function test( obj ) { return obj.prop + obj.prop; } var a = { prop: 'a' }, i = 0; while ( i++ < 10000 ) { test( a ); } output: 1: ~+27(this=0x24e1a2005009 <JS Global Object>) { 2: ~ExtendStringPrototype+23(this=0x3d090ae04121 <undefined>) { 2: } -> 0x3d090ae04121 <undefined> 1: } -> 0x3d090ae04121 <undefined> 1: ~+27(this=0x24e1a2005009 <JS Global Object>) { 2: ~ExtendStringForTemplates+23(this=0x3d090ae04121 <undefined>) { 2: } -> 0x3d090ae04121 <undefined> 1: } -> 0x3d090ae04121 <undefined> 1: ~+27(this=0x24e1a20144b9 <JS Global Object>) { 2: ~ExtendStringPrototype+23(this=0x3d090ae04121 <undefined>) { 2: } -> 0x3d090ae04121 <undefined> 1: } -> 0x3d090ae04121 <undefined> 1: ~+27(this=0x24e1a20144b9 <JS Global Object>) { 2: ~ExtendStringForTemplates+23(this=0x3d090ae04121 <undefined>) { 2: } -> 0x3d090ae04121 <undefined> 1: } -> 0x3d090ae04121 <undefined> 1: ~+51(this=0x24e1a20144b9 <JS Global Object>) { 2: ~test+47(this=0x24e1a20144b9 <JS Global Object>, 0x24e1a2022469 <an Object with map 0x3c6abe514231>) { 2: } -> 0x24e1a20225b1 <String[2]: aa> 2: ~test+47(this=0x24e1a20144b9 <JS Global Object>, 0x24e1a2022469 <an Object with map 0x3c6abe On Wednesday, March 4, 2015 at 2:47:37 PM UTC-5, Jakob Kummerow wrote: > > Try --trace. > > On Wed, Mar 4, 2015 at 8:12 PM, Malek Musleh <malek....@gmail.com > <javascript:>> wrote: > >> Hi, >> >> >> I want to be able trace / record a programs call to its functions (name + >> argument values) either as a separate analysis pass or in addition to an >> existing one (which ever is easier).
