Note to benchmark users: please use ldc compiler with -inline -O -boundscheck=off (or whatever is correct for LDC) options for best results
AFAIK you shouldn't use the -inline flag with LDC, as it tells LDC to run the inline LLVM pass. LDC's inlining is enabled with -enable-inlining and is enabled at -O2 and higher. I believe these are similar except LDC's -enable-inlining has better cost analysis configured for the pass(?)
-inline should probably be renamed because this is confusing due to dmd's usage of it.
But yes, a simple blurb on which compiler flags to use for optimization would probably help as there seems to be some confusion about this due to differing compiler flags. I imagine Iain, Kai, Nadlinger, etc would know which ones to use.
