Removing/deprecating -fvia-c

Hi all, We are planning to remove the -fvia-c way of compiling code (unregisterised compilers will continue to compile via C only, but registerised compilers will only use the native code generator). We'll probably deprecate -fvia-c in the 6.14 branch, and remove it in 6.16. Simon Marlow has recently fixed FP performance for modern x86 chips in the native code generator in the HEAD. That was the last reason we know of to prefer via-C to the native code generators. But before we start the removal process, does anyone know of any other problems with the native code generators that need to be fixed first? Thanks Ian
