Ok I ran the following, just to have a fresh start with the latest sources:
git clean -xdf
git switch emacs-29
git pull
./autogen.sh
export CFLAGS='-g3 -O1 -gdwarf-2 -foptimize-sibling-calls -fdump-tree-tailr'
./configure --with-native-compilation
make
I couldn't find anything searching for the phrases you mentioned,
however. I also don't really know what to look for... I've tried to
gather all of the .tailr1 and .tailr2 files, you can find them
attached. I hope this helps.
