Yes: wtf/NumberOfCores.cpp. I wanted to avoid linking against other WebKit stuff because I wanted something stand-alone that I could give to non-WebKit developers to measure outside the WebKit context. > > PerformanceTests/MallocBench/MallocBench/facebook.cpp:49 > > + Interpreter interpreter("facebook.ops"); > > Is there a way to record these binary files for arbitrary workloads? Sadly, in a fit of silliness, I seem to have lost the FastMalloc patch that does recordings. For any malloc, though, it's pretty easy to produce a recording: Duplicate the "Op" struct, put each allocation+size+slot in a hash table, and dump each malloc/free Op to a binary file as you go. > > PerformanceTests/MallocBench/MallocBench/realloc.cpp:34 > > +void benchmark_realloc(bool isParallel) > > +{ > > +} > > Is this supposed to do anything yet? No -- I haven't filled it out yet, and the script doesn't run it :(. 996813 10 ggaren 2014-04-02 13:20:24 -0700 > Along with style fixes where appropriate.

Might be a good followup bug. I know I've wished for that before when writing new performance analysis tools. Yeah. I spent about 10 minutes trying to do this when I started the project, and then I reached the limits of my Ruby. We should try again: <https://bugs.webkit.org/show_bug.cgi?id=131122>. 996841 13 ggaren 2014-04-02 14:01:54 -0700 > Looks like the main thing that needs fixing is order of system header includes. I'll fix that. Actually, I think it's complaining about mbmalloc.h following other things. mbmalloc.h needs to be last because it undefs the malloc APIs to catch errors in benchmarks. Another complaint is "benchmark_" -- I think that's a special case because it's a global convention for mapping strings to function names. Another complaint is "^{" -- but that's correct for blocks. Another complaint is long_options.
