> curious how D's reference compiler (DMD) compares to the LLVM/GCC front-ends On my machine (an old i7-8700), dmd performs rather poorly. 3.5 seconds. dmd -O leibniz.d Measure-Command { ./leibniz.exe } | select -expand TotalMilliseconds 3535.823 Comparatively ldc runs in 943 milliseconds: ldmd2 -O leibniz.d Measure-Command { ./leibniz.exe } | select -expand Totalmilliseconds 943.21 I'm sure there is compiler switch magic that I don't know about that could improve them.
