Re: Optimize my code =)

Stanislav Blinov:

LDC yields roughly the same times.

This is surprising.

To me as well. I haven't yet tried to dig deep though.

I have compiled your code with (a single module, 32 bit Windows):

dmd -wi -vcolumns -O -release -inline -noboundscheck matrix3.d
ldmd2 -wi -O -release -inline -noboundscheck matrix3.d

DMD:

multiplicationTest ...
        Time required: 4 secs, 665 ms, 452 ╬╝s, and 2 hnsecs

LDC2:

multiplicationTest ...
        Time required: 2 secs, 522 ms, and 747 ╬╝s
