I also compared my "brand new" Pharo VM compiled with clang (LLVM 5 or
whatever it is called, latest in Xcode 5) on Mac with the downloaded Mac
binary from Eliot (2776) which I presume is... GCC 4.2?
Either way, the results using the bench image was more or less that they
are within a few % of each other. The largest diff was Eliot's being
around 10% faster on ... DeltaBlue I think?
But the point is - clang is obviously working!
Thanks Clément for that bench image, so nice with just an image
PS. I guess one could play the CC flags game indefinitely to find the
best combo for clang, haven't tried.
PPS. Also tried using GCC 4.8.1 and 4.9, but then the compiled VM throws
"Bus error: 10" at me. Note that it compiles using the switches for
clang then... (Esteban and Igor - we need a nice way of switching
compiler in CMakeVMMaker!)
