--- Comment #9 from David Malcolm <dmalcolm at gcc dot gnu.org> --- (In reply to Richard Biener from comment #1) > Does not enabling sanitizer improve things? Removing the sanitizer options speeds up the non-analyzer part of the build, reducing the overall wallclock time of cc1 from about 36s to 21s; the -fanalyzer part of that remains steady at about 16s. Without -fanalyzer, cc1 wallclock is: with sanitizer: ~18s without sanitizer: ~5s
