This is a script that makes it easier to visualize the output from make.
It filters out most of the output, leaving only (mostly) messages about
files being compiled, installed and linked. It is not 100% accurate in
the matching, but I feel it does a good enoug

This patch modifies afdo_set_bb_count to propagate profile information
to outline copies of functions if they are not inlined. This information

Hi,
As discusses earlier, get_original_name is used to match profile binary names to
the symbol names in the IR during auto-profile pass.
I think it could be good to add a link to the mai
