Hello all,
in line with the "deinventing the wheel" movement, I'd like to remove the
TimeValue class from LLDB. I've done some research on a flight this week,
and as far as I can tell all functionality can be easily replaced with
appropriate usage of std::chrono::duration and time_point.
The only parts that are missing are the ability to convert to/from legacy C
types (struct timevalue, struct timespec), which can be replaced by utility
functions.
Also, I've found one use case particularly cumbersome to write in the c++
way: writing out a duration as a fractional number of units (e.g.
milliseconds). So, I'd propose adding the following utility function as
well (unless someone knows a cleaner way to write this):
template<typename DurOut, typename DurIn>
double float_duration(DurIn dur) {
return std::chrono::duration_cast<std::chrono::duration<double,
DurOut::period>>(dur).count();
}
Then, you can write float_duration<milliseconds>(dur) to get the duration
as a fractional number of milliseconds (used in printing time deltas in a
human readable fashion).
Any thoughts or objections?
