--- Comment #18 from David Malcolm <dmalcolm at gcc dot gnu.org> --- I wonder if it's worth injecting the equivalent of -fno-diagnostics-show-caret into the Fortran FE for when it's throwing away diagnostics, perhaps by turning gfc_buffer_error's bool flag into a tri-state: * unbuffered * buffered * discarderd With the bogus linemap removed, median of 3 runs: real 0m38.898s user 0m38.234s sys 0m0.505s and median of 3 runs with -fno-diagnostics-show-caret: real 0m38.400s user 0m37.729s sys 0m0.539s so adding -fno-diagnostics-show-caret makes it take only 98.7% of the wall time of the old.
