Here are statistic for inedges. We track mismatches after alignments RTL pass since it is last one, so it cummulates all the mismatches through the pipeline. Martin was objecting agains tracing all the passes independently. https://lnt.opensuse.org/db_default/v4/CPP/graph?highlight_run=42409&plot.0=353.964.7 ^ permalink raw reply [flat|nested] 4+ messages in thread

Still there are some more visible regressions that can be understood. I looked into range for first and did not see obvious candidate. 2022-05-04 g:d7de15fd93fc654e to 2022-05-06 g:37f57a3f4e48fe1a 2022-07-02 g:ed974488991256c5 to 2022-07-06 g:d1f3a3fffeb40e64 2022-09-28 g:5d7be27bf7ef63c7 to 2022-09-30 g:43faf3e5445b5717 ^ permalink raw reply [flat|nested] 4+ messages in thread
