Has anyone had experience in profiling C programs on the Amiga? The ideal tool would be something like the Sun C profiler which provides a breakdown on each function, indicating who called what how often, how much time per call, etc. Since this is not available, the only option seems to be to insert calls to timers. The one function described in the Intuition manual returns seconds and microseconds, but this function is supposed to be inaccurate, (and it causes my system to guru). Does anyone know of any other tools or timer functions that would be of use? A Sun-style profiling tool is my candidate for the Next Great Thing after SDB (which I love). Jack Orenstein

Tom Rokicki wrote one for Manx C; it's on fish disk 48, and comes with Manx C too. It's available for FTP on swan.ulowell.edu - check out /amiga/dos/profile.1of1 for the source code. ..Bob -- Bob Page, U of Lowell CS Dept. page@swan.ulowell.edu ulowell!page

So you're already using Manx. I released a profiler for Manx 3.4 (I believe) that should still work with 3.6, or can be easily modified for 3.6. If a few people ask, I may improve the way it works. But grab it and look at it, let me know what you need. Oh, what fish disk is it on? One second . . . disk 48. And it is for 3.30e, but like I said, the changes should be minimal.

It's easy to use, gives a report of time spent in each routine, percentage of time in that routine and percentage of time in that routine and its children, along with some other stuff...a *must* for speeding up those C programs. > Oh, what fish disk is it on?

It is also distributed with Manx 3.6 (and was distributed with 3.4). -- "Now here's something you're really going to like!" -- Rocket J.

But >grab it and look at it, let me know what you need. It does in fact work with Aztec 3.6, I've been getting alot of mileage out of it since I first installed it on my hard drive. I have found that sometimes it gets confused by the presence of machine language routines, it uses the link instruction to hook in to a procedure it seems, but I often have no need of this in an assembler routine so I leave it out. This confuses the heck out of it. You can find p1 & p2 in one of the example directories on your Manx originals just waiting to be compiled. Well, it was on the 3.4 disks anyways, it might not be the 3.6 disks... -Rico

It's easy to use, gives These are the comments that keep the code coming (from me, anyway.) Folks, if you use someone's code, it's real nice to send them a short note just saying `thanks', whether it's PD or Shareware. It certainly helps me gauge which of my programs are in use and thus deserve further development. On Monday I plan to release V1.1 of the profiler; you want it. It now handles multiple hunks, recursion, and PAL systems (and gives more accurate times to boot.) I hope to have it both compiling under and profiling Lattice by then as well . . . -tom -- /-- Tomas Rokicki /// Box 2081 Stanford, CA 94309 / o Radical Eye Software /// (415) 326-5312 \ / | . . . or I \\\/// Gig 'em, Aggies!
