I'm trying to use the `-profile` flag for DMD and, without any documentation, I can't really understand the resulting log files:

* They contain only mangled names. Is there a way to get demangled, human-readable symbols?

* Can someone tell me what the numbers means?

Is there a page somewhere on dlang.org that explains how to use the profiler?

Thanks,


Philippe

pipe it though ddemangle tool. I though it was shipped with compiler.

Ticks spent in this function. One column specifies inclusive time (the whole call-tree of that function) another one exclusive - time spent exactly in this function not its children.

Maybe it is :-) I never used it, though.
Will it automatically demangle all mangled symbols it finds? Can I use
it on other outputs with mangled symbols?

OK. I get it.

There it is! I knew I saw some page on profiling long ago. Must have been before the switch to dlang.org. Thanks a lot.

Please file a bug on this.  The docs should be on dlang.org.

What Plattform are you profiling on?

Linux  32bits. Does it change something? I'm not using any OS-specific part of Phobos, AFAICT.

Doesn't really change something. But if you would have been profiling on Windows I could have recommended some profilers / tools.
