similar to: [LLVMdev] Fwd: Re: Adding an attribute to clang

Hi, I'd like to track not just at the function level, but also at the code block level. For example, for a if-else statement, I want to know when the if-branch or else-branch is enter/exit. Is there a clang option similar to -finstrument-functions for code blocks? Alternatively, I could manually insert the code to the IR .ll file. I see the generated .ll use the following function when

Thanks Vedant, and my apologies for the delay getting back to you - work got "busy". I wasn't aware of the '-fprofile-generate' option, so thanks for point this out. I have tried running it and I can see the instrumentation hooks that it generates - I assume that there is a library I have to implement to support this, can you let me know where the source for this library

There is some misunderstanding about the intention of this flag. The purpose of the flag is not to turn on profile instrumentation (which already has -fprofile-instr-generate or -fprofile-generate for it), but to select which instrumentors to use for PGO (IR or FE). I prefer fewer flags too, but sharing flags for completely different purpose does not seem like the right thing to do. David On

I would love to see this kind of order profiling support. Using dtrace to generate function orders is actually really problematic because dtrace made tradeoffs in implementation allowing it to ignore probe execution if the performance impact is too great on the system. This can result in dtrace being non-deterministic which is not ideal for generating optimization data. Additionally if order

Hi all, Annoying issue.. my ThinkPad T61 has an iwl4965 wireless card. When I have the wireless switch on, I experience a lot of issues.. system keeps freezing..unfreezing..freezing..etc. Sometimes, a soft lockup is logged to /var/log/messages. psmouse.c also sometimes throws an error saying the mouse lost synchronization. Obviously, this is causing the system to freeze for a sec and

When either '-pg' or '-finstrument-functions' is used, the compiler inserts the appropriate profiling hooks. This happens prior to inlining, so the hooks remain in place. Normally this is fine, but with C++ and the heavy use of inline functions and templates, there can be a vast number of trivial functions that are normally optimised away; but with the instrumentation hooks

This happens prior to inlining, so the hooks remain in place. Have you tried compiling with -fprofile-generate? It enables IR-based profiling instrumentation, which

Hi , Recently upgraded from 2.0.6 to 2.2.2 Samba runs on an E4000 using Solaris 7 ver 11/99 32 bit When installing VB apps on client boxes under NT 4 service pack 6A the installation stalls for 60 secs after 34% & then completes. For users who have Windows 2000 installed there is no problem. Also under the previous Samba version there were no problems installing for either NT or 2000

Hello people on rails, I am developing a web interface for a database that has hierarchical data. I want the user to be able to browse the tree (~1300 nodes) and activate/deactivate and showing/hiding groups of nodes (like selecting one node selects all the children and the leafs). So I have a tree of objects (ActiveRecord acts_as_tree). Because I need the tree to be persistent and I
