I used dmd compiler from site: https://dlang.org

In makefile I change DC to dmd

ifeq ($(DC),)
DC = dmd
endif

1) dmd produces slow executables (about half speed for Amoeba). It is better to use ldc2 or gdc.

2) From the command line, there is no need to edit the makefile to change the compiler, just do

Code: Select all

DC=dmd make
to build amoeba with dmd or

Code: Select all

DC=ldc2 make pgo
to build amoeba with ldc2 and profile guided optimization.

3)I do have an old mac mini (a core 2 duo from 2009) somewhere, I will try to build a faster executable with ldc2. Unfortunately, It does not support popcount instruction, so I cannot test the fastest version.
