I've crawled around js/src/ and attempted to summarize the various APIs used for profiling-related tasks. Some of these are straight profilers, some are general debugging hooks.
vtune
- #ifdef MOZ_VTUNE
- jsdbgapi: start/stop/pause/resume API
- global functions for JS shell & mozJSComponentLoader (NOT xpcshell!)
shark
- #ifdef MOZ_SHARK
- jsdbgapi: start/stop/connect/disconnect API (2 unused; should be static?)
- global functions for JS shell & mozJSComponentLoader & xpcshell
- command-line option -k for JS shell & xpcshell
callgrind
- #ifdef MOZ_CALLGRIND
- jsdbgapi: start/stop/dump API
- global functions for JS shell & mozJSComponentLoader & xpcshell
dtrace
- #ifdef INCLUDE_MOZILLA_DTRACE
- start/stop API unnecessary
- jsdtracef: enter/exit/execute-enter/execute-exit/objectCreate/finalize probes
- probes in jsgc.cpp, jsinterp.cpp, jsobjinlines.h (obj create), NOT jstracer
jscall (bug 507012)
- #ifdef MOZ_TRACE_JSCALLS
- jsapi.h, jscntxt.h: get/set callback API
- piggybacks on dtrace probes but adds in jstracer probes
- start/stop done in nsJSEnvironment (bug 580055), may add a js/ variant
debughooks (jsdv1)
- unconditionally included
- jsdbgapi: get/set/clear
- specific hooks enumerated in JSDebugHooks in jsprvtd.h
- jsprvtd.h: interrupt/newScript/destroyScript/execute/call/throw hooks + some debugger,source code,error stuff
- hooks in jsinterp.cpp (almost everything here), jsscan.cpp (source code), jsscript.cpp (newScript,destroyScript), jstracer (callHook when synthesizing a frame)
- usage disables trace JIT
jsdv2
- sorry, I don't know where this is to look at it. I've only read the spec.
