           Summary: Fine-grained JSC JIT code profiling at the function
                    level
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: yuqiang.xian at intel.com
                CC: barraclough at apple.com, fpizlo at apple.com


This tends to add fine-grained JIT code profiling support with which we can get more detailed information at the function level. A symbol table is created in CodeProfile to manipulate the symbols (consisting of function names (if available) and line numbers), and the samples on different JIT functions are reported separately.

Patch forthcoming.
