There are three somewhat worrisome regressions in execution time: 1) sse_expandfft -- when I build this, the binaries have no differences before and after 2) sse_stepfft -- ditto 3) matmul_f64_4x4 -- this one is interesting The last one represents the only real regressions I expect to see with the new pass. There is a helpful indicator about what caused it: the compile time *improved* by 44%!!! This is because the benchmark was tickling the bad behavior of the old...
