We have open-sourced AutoFDO profile toolchain in:
https://github.com/google/autofdo
For GCC developers, the most important tool is create_gcov, which
converts sampling based profile to GCC-readable profile. Please refer
to the readme file
(https://raw.githubusercontent.com/google/autofdo/master/README) for
more details.
To use the profile, one need to checkout
https://gcc.gnu.org/svn/gcc/branches/google/gcc-4_8. We are working on
porting AutoFDO to trunk
(http://gcc.gnu.org/ml/gcc-patches/2014-05/msg00438.html).
We have limited doc inside the open-sourced package, and we are
planning to add more content to the wiki page
(https://github.com/google/autofdo/wiki). Feel free to send me emails
or discuss on github if you have any questions.
Cheers,
Dehao
