So... There's that.
Changing the code generator to output a set of if statements that
implements a binary search did more-or-less nothing with the DMD
timings, but brought GDC's lead up to 49%. (i.e. the GDC-compiled
version executes in 51% of the time that the DMD-compiled version
does)
the LLVM optimizer is also very good (sometimes far better then the gcc
one) - what are your LDC timings?
