...et 90% of the benefit of a fully concurrent design with almost zero work. But now it seems that this usage model is frowned upon. What is the recommended usage model?

...ne detailed just above that section. I now understand the difference, but I believe a reader who is approaching this for the first time could be misinterpreting the guide and they could assume the instrumentation approach also produces a sampling profile file in the ASCII format.

...endors would need to release the renamed tools, but this often happens anyway with cross-compilers. This pushes some burden on the vendor, but it is much less than maintaining a lot of private changes to the open-source code and tests. What does the community think? Discuss. :-) Cheers, Dario Domizioli SN Systems - Sony Computer Entertainment Group -------------- next part -------------- An HTML attachment was scrubbed...

...>From experimenting with the latest trunk I can see the latter is correct (well, at least the file I get is not ASCII text). Should we update the Clang user guide documentation? Or am I just getting confused? Are there two formats, one used for coverage and one used for PGO?

Can you tell us if you're continuing to use the same approach as described in one of the LLVM meetings, i.e. instrument at the clang AST level? Also, do you generate GCOV files, some yaml, or is this a separate format? And finally in the meeting you had given how you assign counters to the blocks, an algorithm to minimize the number of insertions. Is that algorithm a well-known one or a
