So, I did some more testing with the one processing in
paralel:
--- dmd:
4 secs, 977 ms
--- dmd with flags: -O -release -inline -noboundscheck:
4 secs, 635 ms
--- ldc:
6 secs, 271 ms
--- gdc:
10 secs, 439 ms
I also pushed the new bash scripts to the git repository.
Flag suggestions:
ldc2 -O3 -release -mcpu=native -singleobj
gdc -O3 -frelease -march=native
Tried it, here are the results:
--- ldc:
6 secs, 271 ms
--- ldc -O3 -release -mcpu=native -singleobj:
5 secs, 686 ms
--- gdc:
10 secs, 439 ms
--- gdc -O3 -frelease -march=native:
9 secs, 180 ms
That's very different to my results.
I see no important difference between ldc and dmd when using
std.math, but when using core.stdc.math ldc halves its time where
dmd only manages to get to ~80%
