I don't think we need a new flag for it, I'd just change the output to have 6 instead of 3 digits precision. |
That's a valid point but I believe having choice is better for the human use as the output is easier to read. |
We have too many flags. If we do end up with a new flag, I'd prefer the name to be more explicit, and easier to find next to the old flag, so something like |

There was a problem hiding this comment.
To reduce the diff with upstream, is it possible to use !Clflags.timings_precision directly from Profile.time_display?
Not possible (cyclical dependency). |
no, it belongs in |

When using
-dtimingsflag to benchmark the compiler the values we get are seconds, rounded to the third decimal place.When adding that for thousands of files the rounding error quickly adds up and can produces strange atrifacts in the summary.
This PR adds a new flag
-dtimings-precision. With that the precision of the output can be changed. The default is3same as before.
