It's riscv_rtx_costs.
(I don't usually read ChangeLog entries that closely, just happened to
stumble on it when poking around.)
Using contrib/git-commit-mklog.py can help here to make sure you
always get the correct format for the changelog and it does a decent
job of figuring out function names too.
You can also use contrib/gcc-git-customization.sh to install it such
that you can use it when doing git commits.
After invoking that inside the GCC git; you can just do "git
gcc-commit-mklog ...." Where .... would be what you normally put for
"git commit" (but as if in the toplevel directory).
Thanks, that's awesome.
