问题 I want to use Shark on OS 10.5 to do some basic profiling of my iPhone game (Open GL ES + Objective C). How exactly can I do this?

问题 We are trying to run shark on our iphone application. However, in the analyzed samples it does not list any of our application function. All that is listed are the libraries and when we click on any of those, the assembly code is visible. Most of the sites mention about 'Generate Debug Symbols' option when building the app; I am not able to find this option either. Instead I have enabled the 'Generate Profiling Information' option. Can anyone please help as to how do I see my application

Why is “Run > Run with Performance Tool > Shark” always gray in Xcode? How to call that?

问题 There's this Shark entry in my run menu. But it's always inactive. What's wrong? New xcode with Snow Leopard. Installed all developer tools including CHUD from scratch. Shark itself runs but sees no devices, even though xcode does. it builds and runs on the device. no issues. 回答1: I see the same issue when working in iPhone Apps. For MAC Apps it is not greyed out on Snow Leopard for me at least. So... I suggest build and run your application, then find the Shark Application and launch it

问题 I am using Shark to profile my application on iphone. As per instruction in Shark user guide from http://developer.apple.com/iphone/library/documentation/DeveloperTools/Conceptual/SharkUserGuide/SelectingExecutiontoSampleorTrace/SelectingExecutiontoSampleorTrace.html#//apple_ref/doc/uid/TP40005233-CH13-SW19 I am able to generate profile for my application. But most of functions in my application appear as unknown under symbol header. This is because I am using release version of application.

What makes Apple's PowerPC memcpy so fast?

由 空扰寡人 提交于 2019-12-04 16:05:32
问题 I've written several copy functions in search of a good memory strategy on PowerPC. Using the Altivec or fp registers with cache hints (dcb*) doubles the performance over a simple byte copy loop for large data. Initially pleased with that, I threw in a regular memcpy to see how it compared... 10x faster than my best! I have no intention of rewriting memcpy, but I do hope to learn from it and accelerate several simple image filters that spend most of their time moving pixels to and from memory
