If you would like my makefiles, I can post them on my website.

I use MSVS 2008 for my builds.

I would like a copy. I assumed you were using Intel C++.
There are 6 files in the archive:
----------------------
Make files for 32bit PGO
pgi.xp
pgo.xp
----------------------
Make files for 64bit PGO
pgi64.xp
pgo64.xp
----------------------
Profile suite to gain your profile to merge into final exe.
profile.txt
profile.cmd
----------------------
I simply run in a MSVS command prompt:

nmake -f pgi(64).xp

Once finished the first stage, I run the profiler:
profile.cmd

This take about 3-4 minutes to complete.

Then of course pgo(64).xp. This produces the final exe.

I have found that using the arch:blend is much better than using arch:EM64T or arch:AMD64 (64 bit build) when profiling. Don't ask me why, but it seems to do a much better job.

If you can find any better options, please let me know.

Peter
Thanks, I will do some experimentation with it.
I will probably also try to generalize it for use against any generic project rather than just crafty.
