The tracker just compiles test-suite under `perf stat` using the cached cmake configs. If I pick out the file with the largest regression (mafft `constants.c` in `ReleaseThinLTO` config with 18% regression) I can reproduce this locally as follows: perf stat /home/nikic/llvm-project/build/bin/clang -DNDEBUG -O3 -fomit-frame-pointer -flto=thin -DNDEBUG -w -Werror=date-time -DLLVM -MD -MT MultiSource/Benchmarks/mafft/CMakeFiles/pairlocalalign.dir/constants.c.o -MF MultiSource/Benchmarks/mafft/CMakeFiles/pairlocalalign.dir/constants.c.o.d -o MultiSource/Benchmarks/mafft/CMakeFiles/pairlocalalign.dir/constants.c.o -c ../MultiSource/Benchmarks/mafft/constants.c This gives me 3.5M instructions before and 4.2M instructions after. Those particular numbers are for an assertion-enabled build (the numbers on the website are without assertions.)
