Message:

Add the ability to trace JavaScriptCore garabge collections using dtrace.

Reviewed by Sam Weinig.

  • JavaScriptCore.xcodeproj/project.pbxproj: Generate the dtrace probe header

file when building on a new enough version of Mac OS X.

  • JavaScriptCorePrefix.h: Add our standard Mac OS X version detection macros.
  • kjs/Tracing.d: Declare three dtrace probes.
  • kjs/Tracing.h: Include the generated dtrace macros if dtrace is available,

otherwise provide versions that do nothing.

  • kjs/collector.cpp:

(KJS::Heap::collect): Fire dtrace probes when starting a collection, after the
mark phase has completed, and when the collection is complete.

  • wtf/Platform.h: Define HAVE_DTRACE when building on a new enough version of Mac OS X.
