April 02, 2012Compiling with gdc vs. gdmd
Hello all, First, congratulations to the GDC team -- I'm playing with D for the first time in quite a while thanks to the up-to-date gdc 4.6 packages in the upcoming Ubuntu LTS release. It's great to see that D 2.0 now has this kind of mainstream distro support. Anyway, a question about the gdc versus gdmd interfaces to the compiler. I've noticed that compiling with the options gdmd -O -release -inline produces a much faster executable (about twice as fast) as the typical gcc-style options I would use, gdc -O2 [or -O3] Can anyone advise on appropriate gdc options to pick up the same speed level? Thanks and best wishes, -- Joe

Basically -frelease is missing. Use -vdmd with gdmd to see the command.
