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.
